201232139 VI. INSTRUCTIONS: [Technical Fields of the Invention] The present application is related to the following patents: U.S. Patent Nos. 6,473,072 and 6,738,050; U.S. Patent Nos. 7, 〇 3, 854, 7, 312, 784 and 7, 705, 824; U.S. Patent No. 7,1,1, 164; and U.S. Patent Nos. 6,473,072 and 6,738,050, the disclosures of which are incorporated herein by reference. The present invention is primarily directed to such optoelectronic displays using solid state electro-optic media, wherein the term is defined in the following description. [Prior Art] The technical background of the naming principles and current status of electro-optical displays is discussed in detail in U.S. Patent No. 7,012,600, and the reader is referred to the contents of the case for further information. Based on this, a brief summary of the naming principle and the status quo is given below. In this context, the term "electro-optic" as used in the art of illuminating technology is used to mean that there is a difference between the at least one light characteristic and the second display. A material of the state that, by applying an electric field to the material, changes the material from its first display state to its second display state. Although the human eye has always been aware of the light characteristics of the color, there may be another optical characteristic such as light transmission, reflectivity, luminescence or a false change in the reflectance of the electromagnetic wavelength outside the visible range of the display intended for machine reading. Color 201232139 (pseudo-color) 使用 The terms "bistable" and "bistabiHty" are used in this document to mean having a phase in at least one optical property.夕夕筮—B„ 邳呉 邳呉 一 一 一 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示 显示Display state, after the address pulse has been terminated, the strong standby 4 main connection, instrument. The state will last for at least several periods, such as at least four periods, this is a change of f Gu ~ I and nothing The minimum period of the required address pulse. The material may have 'and often has a space for filling liquid or gas internally'. Some electro-optic materials are solid, meaning that the material has a solid external surface. See 'This type of display using solid-state electro-optic materials can be used as a "solid-state optoelectronic display". Therefore, the term "solid-state optical display" includes a rotating two-color member display, an encapsulated electric ice display, a micro-cell 7L (miCrocells) electrophoretic display, and a capsule liquid crystal display. There are several types of optoelectronic displays known, for example: (a) Grain-to-two-color component displays (see, for example, U.S. Patent Nos. 5,808,783, 5,777,782, 5,760,761, 6,054,071, 6,055,09 1 '6, 〇97,53 1,6, 128,124,6,1 37,467 and 6,147,791); (b) Electrophoretic display (see, for example, the natural nature of Oregan (〇, Regan, b) et al. 1991, 3 53 ' 7 37 ; Wood (Wood, D.)

"Electric wet-based video speed electronic paper", natural, 425, 3 83-3 85 (September 25, 2003) and U.S. Patent Publication No. 2005/0151709); (d) Particle-based electrophoretic displays in which a plurality of charged particles move through a fluid under the action of an electric field ( US Patent No. 5,930,026 '5,96 1,804 ' 6,017,584 ' 6,067,1 85 ' 6,1 1 8,426 ' 6,1 20,588 ' 6,1 20,839 ' 6,124,85 1 ' 6,130,773 and 6,1 30,774; US Patent Application Publication No. 2002/0060321, 2002/0090980, 2003/0011560 '2003/0102858, 2003/0151702, 2003/0222315, 2004/0014265, 2004/0075634, 2004/0094422 , 2004/0105036, 2005/0062714 and 2005/0270261; and International Application Publication Nos.

There are several different types of electrophoretic media variants. Electrophoretic media can use liquids or gases. For gases, see, for example, Kitarnura et al., "Electronic toner movement for electronic paper displays," IDW Japan, 2001, paper HCS1-1 , and Yamaguehi et al., "Use of a toner display with friction-charged insulating particles", IDW Japan, 2〇 (H, Paper AMD4-4; US Patent Publication No. 2005/00018 10; European Patent Application -5- 201232139 1,462,847 ' 1,482,354 ' 1,484,635 ' 1,500,97 1 ' 1,501,194 ' 1,536,27 1 ' 1,542,067 , 1,577,702 , 1,577,703 and 1,598,694 ; and international applications W02004/090626, W02004/079442 and W02004/001498. The equivalent medium encapsulated into capsules 'contains a plurality of capsules, each of which includes an internal phase' which contains electrophoretic migrating particles suspended in a liquid suspension medium and a capsule wall surrounding the inner phase. Mounted in a polymeric binder to form an adhesive layer disposed between the two electrodes, as described in the MIT and E Ink patents and applications above. Alternatively, a continuous phase can be substituted The discrete microcapsules surround the wall in the encapsulated electrophoretic medium, thus producing a so-called polymer-dispersed electrophoretic display, wherein the electrophoretic medium comprises a plurality of discrete droplets of electrophoretic fluid and a continuous phase of the polymeric material, see for example US patent Case No. 6,866,760. For the purposes of this application 'This polymer-dispersed electrophoretic medium is considered a subclass of encapsulated electrophoretic medium. Another variation is the so-called "microcell electrophoretic display" in which charged particles and streams The system is indwelled in a plurality of cavities formed in a carrier medium. The carrier medium has been a polymer film, for example, see U.S. Patent Nos. 6,672,921 and 6,788,449. The encapsulated electrophoretic display has never been compromised by conventional electrophoretic devices. Clustering and precipitation failure modes, and provide the advantages of further steps, such as printing or coating the display on a variety of flexible and rigid substrates. ("Printing") is used to cover all forms of printing.

The device can be tractable. Furthermore, since the display medium can be printed by using a female L (using various methods), the display itself can be inexpensive. Although the electrophoretic medium is often opaque (for example, due to the fact that in many electrophoretic media, the particles are substantially resistant The visible light is transmitted through the display and operates in a reflective mode. A multi-electrophoretic display can operate in a so-called "gate mode" in which one display state is substantially opaque and one is light transmissive. For example, see the above-mentioned U.S. patent. Case numbers 6, 13〇, 774 and ΜΑ·; and US patents 5,872,552, 6,144, 36i, mu., 6,225,97i and 6,1,84,856. Similar to electrophoretic displays, they rely on double electrophoresis of electric field intensity changes. It can be operated in a similar mode; see U.S. Patent No. 4, 4 1 8, 3 4 6. Other types of electro-optical media are also in the present invention. U.S. Patent No. 7" is well-known: there are two electro-optical displays (including capsule electrophoresis). The assembly method of the display). Basically, this patent description says that the moonfield @"front panel laminate" ("fr〇nt ρΐ_

Uminate 'WpL")) 'sequence includes a light transmissive conductive layer, a solid electro-optical medium (four) in electrical contact with the conductive layer, an adhesive layer, and a release sheet (4) (10) sheet. The light transmissive conductive layer is carried on the light transmissive substrate. , 201232139 is preferably 'flexible' means that the substrate can be manually wrapped around a (for example) 10 inch (254 mm) diameter drum without permanent deformation. The term "light transmission" is used in this patent. It is intended that the layer thus designated transmits sufficient light to allow the observer to see through the layer to observe changes in the display state of the electro-optic medium. It is typically observed through the conductive layer and adjacent substrates (if present); In the case where an electro-optic medium exhibits a change in reflectance of an invisible wavelength, the term 'of course, light transmission' should be interpreted to mean the transmission of the associated invisible wavelength. The substrate is a polymeric film and typically has a thickness in the range of from about 1 to about 25 nul (25 to 63 4 μm), preferably from about 2 to about 1 〇 π ήΐ (5 1 to 254 μηΊ). The conductive layer is conveniently a thin metal or a metal oxide layer such as aluminum or ITO, or may be a conductive polymer. Commercially available are polyethylene or terpene coated polyethylene terephthalate (PET) films, such as "Aluminized Mylar" from E. I_ du Pont de Nemours & Company, Wilmington DE ("Myiar" , is a registered trademark), and such commercial materials can be used in the front panel laminate with good results. The assembly of the photoelectric display using such front panel laminate can be achieved by laminating the release sheet from the front panel and making the adhesive layer Under the effective conditions, the bottom plate is contacted, so that the adhesive layer is adhered to the bottom plate to complete, so that the adhesive layer, the electro-optic medium layer and the conductive layer are placed on the bottom plate. The front panel is laminated to produce a 'roller-to-roller coating technique' And then the cutting board uses the required y^, Λι low-size fragments, so the process is fully produced. "Li _ (see above patent and application) provides photoelectric display with touch screen Not good. Many display applications benefit from touch sensitivity. In many cases, 'a touch of sensitivity in a limited number of fixed areas can be used: Make 201232139 user interface elements., Transform The user can replace the method, such as drawing, scribing or complex, and can provide the production of electronic 纟 2 = benefit from the full touch screen. The touch sensing capability is not only imitating the possibility that the paper is not good. The electronic paper-like display measures the readability and writability of the finger or stylus in the sheet. The ability to check the information frequently to complete the selection of the M display screen enables the display to use the position print. The selection of early items or the capture of handwriting as a "digital sign. Although the touch sensor is always regarded as ^2, it is not a display function, and the touch sensing is set at the same time (in the factory, the staff is not part of it). Because it must be combined with the monitor to touch the screen technology; above or below the surface of the watch. Unfortunately, most of the main ^ is suitable for portable products using electrophoretic display. Bubei, smart day screen The type of force demand is low enough to meet the touch interface of such a display. Hui Hui needs to stack multiple layers on the top of the display medium and / or "under-display is reflective, subject to each additional layer and between the electro-optical layer and the user eight 'Interface' to reduce light efficiency. Many types of touches also add too much thickness to the stack of displays, and multiple additional processing steps are required to form a complete display panel. The inductive touch screen can be placed behind the bottom layer (that is, on the opposite side of the bottom plate for the user and the electro-optical medium), and thus does not affect the light effect. The minimum thickness is added, but it is expensive and requires a special stylus. The surface capacitive touch screen is used for the front of the photoelectric display. This type of touch screen has always been layered or placed on the front of the finished display. As shown in Figure 1A of the accompanying drawings, a typical form of such a touch screen has a substrate 1 'p-polyphenylene terephthalate (pET) having a thickness ranging from about 50 to 201232139 of about 25 〇μΐη. form. The light transmitting and conducting layer 2 is formed on the surface of the substrate}. Layer 2 may be formed from oxidized steel kick (ITO) or any other light transmissive conductor such as PED〇T, nanocarbon f or other inorganic conductor. If the impedance of layer 2 is not too low, the actual touch screen effect is better, and the preferred range is about 丨 to 5

A low-profile resistive material 3 (which has always been a silver-printed silver ink) is formed and patterned in contact with the conductive layer 2. As discussed below, the various materials of material 3 are used in several functions.

Crystal-cut ring ~ touch sensor at the edge of the special -10- 201232139 SUMMARY OF THE INVENTION In one aspect, the present invention provides several methods for integrating a capacitive touch sensor into a front panel laminate to produce a ready-made single film for assembly into a display. The bistable nature of electro-optic media potentially allows for multiplex processing of various electrode structures in a display between a drive display and a sensed user input. Electrophoresis and other bistable electro-optic media ratios may be more stringent in liquid crystal displays. Touch screen integration. This is not possible in liquid crystal displays, because it is necessary to continuously drive such displays. There is no opportunity to use any sensor structure for touch sensing. Another aspect of the present invention provides A display having a proximity sensing device that detects when the user approaches the display, or more specifically near the screen. The second aspect of the invention relates to incorporating a resistive touch sensor into the optoelectronic device In a display, the fourth aspect of the invention relates to the integration of a display and a main input device in an optoelectronic display. More specifically, in one aspect, the invention Provided for an optoelectronic display, comprising: a light transmissive conductive layer having a plurality of conductive members having a higher conductivity than the conductive layer at the periphery; a layer of the electro-optic material; and a bottom plate having a plurality of pixel electrodes, the photoelectric display further Including a means for controlling the potential of the plurality of conductive members, such that a plurality of conductive members and a light-transmitting conductive layer can be used as a touch screen. In one aspect, the present invention provides an article (front layer) comprising, in order: a light-transmitting conductive layer having a plurality of conductive members having a conductivity higher than that of the lead portion; a layer of solid electro-optic material layer; a layer of adhesive layer In another aspect, the present invention provides an optoelectronic display comprising: a sequential light transmissive conductive layer having a plurality of conductive members with a conductivity at a peripheral portion thereof; a conductive layer light transmissive electrically insulating layer; a light transmissive conductive layer; a solid electro-optic material layer; and a bottom plate with a plurality of pixel electrodes, the history of which is used to control a plurality of conductive The means is such that a plurality of conductive members and light are transmitted through the screen of the I potential. Adding this as a touch in another aspect t layer), in order to include: The present invention provides an article (a front panel light-transmitting conductive layer, a plurality of conductive members having a conductive coefficient in the periphery of the kangaroo; Conductive layer light transmissive electrically insulating layer; light transmissive conductive layer; -12- 201232139 solid electro-optic material layer; and laminated adhesive layer; and release sheet. In another aspect, the present invention provides an optoelectronic display comprising: a light transmissive conductive layer a solid-state electro-optic material layer; a bottom plate having a plurality of pixel electrodes; and first and second conductive layers spaced apart from each other but facing outwardly, the first and second conductive layers forming a touch screen.

In another aspect, the present invention provides an optoelectronic display comprising: a D light transmissive conductive layer; a solid electro-optic material layer; and a bottom plate with a plurality of pixel electrodes, the periphery of the bottom plate extending beyond the solid electro-optic material layer, and the periphery of the bottom plate The part is provided with a plurality of means for generating a plurality of means and a plurality of means for detecting, and a plurality of light-spots and a plurality of light-spot detecting means are configured as a touch screen [embodiment] as shown above, in a jiazhan 丄々^ In view of the above, the present invention provides a single film for integrating a capacitive touch sensor into a front panel laminate for assembly into a display. For example, the most straightforward 21 to be used for the integration is the conductive layer of the touch screen and the structure shown in Figure 2, which is used as the touch silver, sequentially changing to each other, and sequentially generating the hand toward the epitaxial radiation. Figure 2 is a diagram showing both the single conductive layer top electrodes. Method, the production method is the base of the display device -13- 201232139 The front substrate 22 of both the front surface of the substrate faces the viewer 24. - and several materials 23 (similar to the ones shown in Figures 1 and 1 are similar to those provided on the bottom plate 27) are placed in the swimming layer 25 (although not shown in Table 26: = layer (such as microcapsule charging) Between the pixel electrode 26 and the pixel electrode 26, there is usually a 'layer of adhesion layer in the electro-optic layer 25, and a second layer of adhesion layer on the electro-optic layer 25. The bottom plate can be a straight dry, ... and Rigid or reversible. If connected at the edge of 28 conductive adhesives, complete the connection to the conductive layer; 23, although it should be noted that it is not necessary to connect to the conventional technology. The device illustrated in the above requires a separate connection, such as the above reference s 1 Α & 1 , diagram, one connected to the front electrode and four connected to the touch sensor. As described in the above-mentioned U.S. Patent No. 6,982,1 78, The display exemplified in Fig. 2 can be produced by a J-only modification process to construct an electrophoretic display using a front panel laminate. As described above, the FpL process of the prior art includes a (commercially available) IT/PET film. Coating on the surface of the ITO with an electrophoretic medium. Separately, the adhesive is laminated. Coated on the release sheet' and the formed sub-assembly is layered on the electrophoretic medium, and the laminating adhesive is contacted with the electrophoretic medium to form the finished FPL. The release of the release sheet and the accumulation of the retention layer are completed to the substrate with the pixel electrode. Display. To produce the display illustrated in Figure 2, a similar process can be used 'before printing the electrophoretic medium on top, the low-sheet resistive material 23 is printed on the ITO surface of the ITO/PET film. The invention extends to this The front panel of the repaired portion is laminated. Alternatively, the reverse front panel laminate as described in U.S. Patent Application Publication No.-14-201232139, 2007/0109219, and/or U.S. Patent No. 7,561,3,24, The double release film can produce the display shown in Fig. 2. The appropriate multiple of the double release film is substantially covered... The electro-optic layer between the adhesive layers is at least one of the surface of the adhesive layer away from the electro-optic layer, and is preferably Both are covered by a release sheet. Using such a dual release film to produce a display as shown in Figure 2, first modify the ΙΤΰ/ΡΕΤ (or similar) film to a low-sheet resistive material 23 disposed thereon. Next, one of the two release sheets is peeled off from the double release film, and the exposed surface of the laminated adhesive layer is laminated (currently under heat and pressure) at a low sheet impedance The material 23 and the conductive layer 21 thus form a reverse front panel laminate. The remaining release sheet is then peeled off from the sub-assembly thus produced, and the surface of the k-exposed laminated adhesive layer is laminated (currently under heat and pressure) on the bottom plate. The pixel electrode 26 on the 27 is used to produce the final display. This first layer can also form the connection 28. Although the order just described is generally the most convenient for large production, if desired, the order of the two layers can be reversed. The use of a dual release film reduces the difficulty of coating the electrophoretic medium on a heterogeneous surface, and/or inconvenience, because it is easy to coat the electrophoretic medium on the heterogeneous surface by laminating the adhesive layer thereon, Low film = material ^ 3 printed on the surface of the coffee machine to form a heterogeneous electrode 2 wide: wide? The release film 'reverse front panel lamination process provides an alternative way to complete the electrical connection between the front and bottom plates 27, and to connect the four electrical connections. If a low resistivity is formed around the active display edge, the portion of the pixel electrode screen 10 is unobstructed. The conductive channel can alternatively form a touch sensor in the substrate as the layer 10. 2, J: The touch screen display of the present invention is similar to the image, but includes a color filter array 29. This color filter array -15-201232139 is formed on the front substrate 2A and then covered with a bright conductive layer 22. In the display as shown in Fig. 2, only the additional step is required in the display process to print the low-profile resistive material 23 on the conductive layer 22. The display shown in Fig. 3 can be produced using a double release film, reverse 刖 panel build process, which is similar to that described with reference to Fig. 2. FIG. 3 also exemplifies an alternative method of electrically connecting the low-profile resistive material 23 and the conductive layer 22. Instead of the edge connection shown in Figure 2, the third figure shows the use of a flexible circuit tail 3 that is bonded or adhered to the touch pad 6 of the touch screen (see Figure =1B). Regardless of the backplane (although it can be terminated on the backplane itself and thus connected to the controller), the flexibility: the tail 30 is connected to the touch screen controller. The tail of the circuit is therefore required to connect the electrodes to the backplane before the display, thus potentially simplifying the structure of the display. The display + crying device shown in Figures 2 and 3 adds touch screen functionality and the additional cost of light is visible. The active area of the display: = = : or thickness has no effect. However, the size of the surrounding area between the earth and the earth is two. In both displays, the sensing phase is sensed and displayed (ph: during the display driving, the general driver circuit is versatile and can be driven by the touch screen component.

It is about 0V ’ to make it DC balance. This can be used as a masterpiece.. D.

The rounding of the controller, the grounding of the reference controller, or the signal m 0 of the considerable core between the controller and the panel electrode by AC. The other method is to allow the pixel electrode to float during the sensing phase (ie , no driving voltage is applied). In an active matrix display, this is achieved by keeping the rails of one of the gate drivers conductive during the sensing phase, thereby keeping the transistors non-conducting and allowing the pixels to float individually, limiting the electric field to which the electro-optic layer is exposed. Alternatively, the source line of the array can be driven (or the drive line of the display directly driving the viewer) to make the sensing wavelength of the electrode driver fully conductive 'but the implementation of this method is difficult. If the display of the electrical interference between the drive and the touch sensing is considered too large, or if the simultaneous or overlapping display drive and touch sensing are to allow quick response, such as in the drawing operation or fast update Explicit rapid text input during typing can be integrated using its form of touch sensor as an optoelectronic display. Figure 4 illustrates such a form of integration in which the touch silver component is disposed on the opposite side of the substrate from the front of the electro-optic layer, thereby separating the sheet conductor 22 of the control screen from the germanium electrode of the rice display. This allows the touch to be measured by this number and can be completed and the gate is difficult to show its touch. -17- 201232139: Curtain == Conductor can be used as a material for higher electrode resistance before the display, making touch The sheet conductor of the control screen can be formed of an inexpensive, highly light transmissive material such as an extremely thin film or an electropolymer. As discussed above, the light transmission of the film is not significantly reduced. Before the electro-optic medium is applied, in some cases, the roller used in the preparation of the front panel laminate is inexpensively coated with the conductive polymer at ιΤ0/ΡΕΤ骐Painted on a surface that is not ιτ〇. After the panel is laminated in this way, the panel is laminated to the desired size of the display, and the layer required for the touch screen can be applied: Figure 4 illustrates the connection to the touch screen via the tail of the flexible circuit 3〇 'It is connected to both the touch screen and the front electrode, thus eliminating the need for individual connections from the front electrode to the backplane. Alternatively, a multi-layer screen printing technique with vias can be used to provide a connection between the touch screen and the backplane. Fig. 4 also illustrates a protective sheet 31' which is conventionally laminated on the top of the front substrate using a bright adhesive (not shown). The protective sheet 31 is designed to impart the desired mechanical properties to the display for its intended use, and can The UV barrier is combined with a diffuse reflective hardcoat to provide an attractive and durable surface on the display. In the display of Fig. 4, the protective sheet also serves as a capsule and protects the touch screen layer. The display shown in Fig. 4 can be produced using a modified front panel laminate or a modified dual release film/reverse FPL process which is similar to the foregoing for the display of the second aspect. In order to produce the display of Fig. 2, a substrate for producing a front panel laminate or a substrate having a double release film laminated thereon may be modified to provide a front conductive layer 22 and a low sheet resistive material 23 thereon. The slab 3 1 can also be attached to the substrate at this time, but it has been more convenient to attach it at a later stage of the process -18 - 201232139 t. The alternative structure of the structure shown in Figure 4 uses a multi-layer conductive coating having a dielectric layer on the front side; 1 in the electrocoat can be used to guide the viewing surface closer to the display: partial touch Controlled silver | 'The electrode is closer to the conductive layer of the electro-optic medium. Even the two or eight of these electrical layers will block the value of $ ’ and at least isolate the display drive and the two electrical signals to some extent. Finally, FIG. 5 illustrates the modification of the display of FIG. 4, the layer 23 of the control screen is disposed on the inner surface of the protective sheet 31, and the front electrode is advantageously connected to the bottom plate via the edge connector 28. The connection of the control screen passes through the flexible tail 3〇. The fifth display can be produced by merely modifying the protective sheet used in the display, and thus can provide a relatively easy path for the intended design of an optoelectronic display having a touch sensor. As already mentioned, the second aspect of the present invention relates to a display having a proximity device that detects when a user approaches the display or more closely approaches the vicinity of its screen. When the small to medium display makes the electric valley touch sensor, the user needs to approach the display screen to determine the proximity sensor and provide the common mode signal to filter the signals of the four corner sensors, such as Reference! B describes the touch screen of the 'four corners of the sensor forming part. While battery-operated displays use bistable electro-optic media, for pool life, it is desirable to turn off the power to the majority of the display when the user does not interact with the display to write the display. Therefore, one of the multilayer conductive layers of 21 is used as a display for the display of the electric layer control, in which the display is connected to the display of the notice, and the change is sensed: Moreover, there is a useful input if the method of extending the power and not re-detecting the user is -19-201232139. As indicated above in the discussion of the display shown in Figures 1A and 1B, the proximity sensing electrode is a standard feature of a large half-surface capacitive touch screen. This second aspect of the invention relates to a method for providing near-sensing as a partial optoelectronic display backplane or utilizing backplane characteristics to provide such throughput, and for use in a portable display system using a bistable electro-optic medium The method of sensing. The use of backplane features to provide near-sensing with a touch screen disposed on the front panel of the display can result in a smaller boundary size of the touch screen, and potentially lower build costs. (The term "fr 〇nt plane" is used herein in the conventional sense of the art to refer to all of the display layers between the electro-optic layer and the electro-optic layer and the viewing surface. Many optoelectronic displays include boundary or peripheral electrodes, direct drive electrodes disposed adjacent the active area of the display and typically have a width of 1 to 3 mm. This boundary electrode uses a single pixel that determines that the full edge of the display is in the same light state. Without such boundary pixels, the address lines extending across the perimeter of the display can capacitively switch the electro-optic material above them, creating a transfer vision. The boundary electrode also provides some tolerance for setting the display screen relative to the bezel of the housing. In a display using a bistable electro-optic medium, the boundary electrode can be used both by time division multiplexing to propose an electro-optical medium overlying the peripheral portion and as a proximity sensing device. A switch, analog or field effect transistor can be used to isolate the two functions from each other or to design the associated circuitry so that they do not interfere with each other. Alternatively, the dedicated electrode for the proximity sensor can be set on .20-201232139 on the base plate. Although such a dedicated ^ P ^ ^ ^ electrode may be increased, since there are multiple patterned conductive layers on the commercial substrate, the photo inactive region around the bottom plate containing such a dedicated electrode is not It will be expensive. The aforementioned proposal assumes that the touch silver 篡仫 德 + + β ί ·. 4 The figure is built. The screen is built on the front panel of the display. Right only S Sin is sensing and non-secure and non-touch screen performance. The front electrode of the display can be used to drive the display. The IB H1 β , -, and the sensing proximity are time division multiplexed. Brother 1 及 diagram and above related ^ , , At . ^ Month describes the method of proximity sensing and touch screen sex.

In addition to the sensing used in the non-bistable display, the use of proximity, recognition, and characterization is used in the bistable display. It is desirable that the image on the display is static and ϋ

When the At, ,,..., and 匕 devices are in operation, the battery-powered portable bistable display shows that the 奘 + + 丁 装置 device shuts down the power of the Dafeng internal system (ie, enters the deep sleep mode). Autumn, '..., to the obvious latent time associated with wake-up from deep sleep mode, special county. In particular, you need to turn on the display controller and offset charging S to use any of the above technologies, set to use for detection The person approaches and initiates a wake-up procedure that the user is expected to quickly interact with the device. Another use may be to restore the long-term image on the screen when the user is approaching, and thus is somewhat faded. Such a sensor may also use the input device as the device, for example, the prompt may say "tap on the screen to accept", or in the e-book reading, tapping the screen may advance the page" The device is designed to provide a common connection to the common front electrode (IV) I- 21 - 201232139 as a basic differential proximity device, such that, for example, tapping on the silver side on the other side back one page. The third point is about the resistive touch. In the conventional resistive touch-sensitive layer continuous conductive film; the mechanical film is maintained between the conductive films. Place a film on the directional support and the other ("top"). With the electrode, the electro-voltage gradient is applied along the edge. When the pressure is applied to bring the top and bottom film into contact, the film edge of the two layers is laminated. The electrode detects the contact position in the top film. Especially for the relative position, the accuracy of the sensing can be improved. Two kinds of sensors can be used for the control circuit between the touch force and the influence layer. One side of the sensing screen can be advanced by one page and tapped. As already mentioned, the control sensor of the present invention is incorporated into the detector of the photoelectric display. The interval between the two separated by the air gap is called by the machine disposed therebetween. The "base film" is provided on the deformable substrate when the film is applied to the underlying film, and when the film is actually deformed across the film film, a circuit is formed between the layers. By setting the voltage on the top, it is possible to determine the more detailed configuration of the panel of the X and y-dimensional panels. In some cases, the extent to which the contact area may be measured is set. Resistive touch screens have several key advantages over competing technologies, including low cost, robustness and sensitivity to any kind of mechanical touch (some other touch sensors are only for special stylus or human hand) ^ Respond). However, one of the main drawbacks is the brightness and contrast of the display, because in reflective displays, the presence of a resistive touch sensor requires that the light reflected from the electro-optic medium pass through the two additional layers twice. Other disadvantages are the thickness and weight added by the resistive touch system, where the rigid bracket must be rigid enough to not deflect when applying pressure to the front membrane. This is especially important in liquid helium displays because their light characteristics are significantly affected by pressure. -22- 201232139 It has been found in optoelectronic displays that the rigid stent of the prior art > can be thin and possibly flexible. The stiffness required for the operation of the device is due to the thin polymeric film properties provided by the substrate. The photoelectric display of the present invention of the resistive touch sensor of the exemplary f* is shown in the schematic cross section of Fig. 6 with the accompanying drawings: ::=(: order from the bottom plate to the viewing surface) The rigid substrate 40, the thin matrix substrate 42, the solid-state electro-optic medium (the swimming medium), the screen 44 & not the capsule α-sharp electrode 46, the transparent substrate 48, the transparent, t 50 'the air as the resistance-boat Between: 52, the underlying film of the detector, from ... 4 Yong 52, transparent conductive layer 56, the top drawer of the detector, ~ resistive touch ri R, and optical transparent flexible substrate or protective layer 58 to prevent Thunder resistance _v's k increased by 5, harm.

Avoid the provision of transparent reeds on both sides of a single piece. 6, 982, 178 front (4) The front side of the front panel shown in Figures 6 and 7 shows two layers of the substrate on the opposite side for transmitting the conductive layer before the release sheet. In order to produce the 7th sense of control In the other figure, the conductive damage of the electro-optic layer is controlled by a 48B transparent conductive plate, and the substrate display -23 - 201232139 photoelectric display can be provided with light The two separate substrates of the transmissive conductive layer are adhesively bonded together to produce a modified front substrate ^ Screen printing or other processes 玎 optically pattern the second light transmission to provide the characteristics required for the final character of the resistive touch sensor.

The phone number, text message, and other information are entered by touching the screen area that is depicted by a portion of the image and interpreted by the software. Such a "soft" or "virtual" keyboard often has a clear advantage over the traditional keypad, in which the imprint and/or its position on the virtual button can be easily changed by the software, depending on, for example, the local language (different font set), User visuals (large font text) or applications used (eg, text input fonts, dialed digits, and special characters and set of glyphs for specific programs, such as audio or video programming conventions) This allows the device to switch the functions of various buttons for the purpose of the dedicated sound §fl or the pictogram of the video device. In addition, 'in the conventional mobile phone and similar portable electronic devices, the display and the keypad each occupy about half of the available surface area of the device, and the removal of the dedicated keypad and the preference of the virtual keyboard enable the person to roughly double the display size. There is no need to increase the overall size of the device. However, many users complain that the virtual keyboard lacks tactile feedback. When doing another job, such as driving, if the user tries to dial the phone number, the flat surface of the display does not provide information about the button position, or any indication of any tactile or audible feedback to indicate when the button has been pressed. This makes it more difficult to quickly and accurately dial a phone number on a featureless touch screen, and suffers similar difficulties in other types of input sequences. It is almost impossible to touch the type on the virtual keyboard without tactile feedback. U.S. Patent Application Publication No. US 2003/0058223 describes a deformable display disposed on a group of membrane switch "popples". The mechanical pressure on the surface of the display is transmitted through the display to activate the switch on the lower -25 - 201232139 side, which exhibits a non-linear force profile when the switch is deformed ("click", "cliek,"). However, the specific embodiment only illustrates A keypad equipped with a segment display, the segment display can display a limited set of button labels by direct driving of the electrodes. The present invention provides an optoelectronic display comprising an active matrix overlying a group of column switches (buttons) A display that operates the switch by actual deformation of the display under pressure. The active matrix display not only displays the imprint of the button, but also displays all other data that needs to be displayed by the executing application, and therefore, is used as an optoelectronic display. Main screen. Figure 8 is an expanded view of one embodiment of such a screen. As seen in the figure, the display includes a backing substrate 80 having a plurality of columns of pressure sensing switches 82. Overlying the backing substrate A flexible film 84 having an elevated region 86 aligned with switch 82. The selected display layer then includes a column Button 88, which assists in confirming that pressure on any area of the display is transmitted to the closest switch 86. The inert TFT array 90, front panel 92 (including the adhesive layer, the electro-optic layer, and the electrode layer) overlying the button 88 , none of which is shown in Fig. 8 and (optional) protective sheet 94. Fig. 9 shows the appearance of the display shown in Fig. 8 in which the action is performed. Around the side edge of the display and the top The U-shaped area of the edge extension is given to the number of 0. 9. The central part of the display indicates the list of the phone numbers that have been memorized. ^ .· The part below the item is indicated by the phone number of the list. The other functions are shown. The display itself will include a linear array of pixels, the basin is known as a thin gland mine B 1 , and the day-to-day (TFT) is connected to the data bus line, which is gate -26 - 201232139 Controlled by busbars. The TFT array should be constructed on a material under pressure to activate the underlying keys, for example, ρΕΤ, polyfluorene PEN or a thin metal substrate such as stainless steel foil. Prior art TFT arrays have always been square or rectangular , The pattern has a display that allows for the display of potentials with as few bus bars as possible, and: 'is desirable for design reasons to create inclusion or formation cuts, rounded edges or other non-rectangular designs. The invention extends to the fact that the pixel array is non-rectangular and/or packaged. The first diagram illustrates a non-rectangular display in which, when the display width is decreased upward (as exemplified), the length of the data line 1 〇〇 sequentially lower the bus bar 102 is sequentially decreased to coincide with the decreasing of the 11th and 12th. The figure shows two displays with perforations 11 在. In Fig. 11, the source line 112 surrounds the hole 110 to be a non-adjacent portion of the column, and the gate line is not suitable for the hole ιι. Individual gate lines are provided on the left and right sides. Similarly, in the side, the gate line 丨丨4 is wound around the hole 1 10 to start the same column, and the source line is provided above and below the hole 1 1 0 where the source line is separated by the hole. In some displays of the present invention, the user interface can be only roughly input (e.g., yes/no). In this case, it is in the mode of operation of the providing device, wherein the activation of the pre-defined area button produces the same result. Moreover, the overview on the display is mapped to the actual boundary of the button set for the same result. The first example shows a display of this type in which the large "Yes" and "No" strokes and 1 32 respectively extend beyond four of the following pixels 丨34.

The resistive touch screen is also reported by A. It consists of two conductive films of erroneous variable resistance materials. When the pressure is applied to the variable conductive material to make the variable conductive material change, its impedance changes, by the protective belly $T leaf The position and magnitude of this impedance detected by the variable track device will indicate the location and intensity of the touch applied to the system: and 'the appearance of the electro-optic medium used is not significantly affected (eg, encapsulated and polymer-dispersed) When the manual pressure in the electrophoretic medium is affected, the touch screen can be set to electricity. After the light layer (that is, the viewing surface from the display is on the opposite side of the electro-optic layer). An example of such a touch screen display is shown in Fig. 14. In this display, the substrate 40, the bottom plate 42 The electro-optic layer 44, the front electrode consumption and the front substrate 48 are basically the same as those of the display shown in Figures 6 and 7. The components are the same. However, the display shown in Fig. 14 further includes a resistance ^ touch sensing Above the conductor 150', the upper conductor forms a row pattern; 2 4-28-201232139 by the resistive material 1 5

It is desirable that the radiation used is outside the visible range to ensure that no visible radiation fringes are present on the viewing surface. The implementation of this optical touch screen technology in optoelectronic displays has been quite cumbersome and expensive. As illustrated in Figure 15, the implementation of prior art optical touch screen technology has historically included the provision of optically deflected screens. Iigh_deflecting bezel) 1 60, electro-optical module 162 (which includes the electro-optic layer itself, the front substrate, the moon 1J and the bottom plate) and the display of the individual rectangular circuit board 164. The circuit board 164 extends outward The electro-optic module 1 6 2 exposes the peripheral portion of the circuit board 164, and the infrared illuminating diodes (LED's) 166 are disposed along the two edges of the peripheral portion, and the other two edges of the peripheral portion are provided with a pair 29- 201232139 LED's 166 emits a radiation-sensitive photodiode 168. The light-biased screen 160 has a light-biased surface (not shown) that travels from the panel of the board 164 that is emitted from the LED, s I" The radiation is deflected by the screen 16 ,, so that the parallel viewing path is closer to the viewing surface of the electro-optical module 162 (such as the upper surface illustrated in the second drawing), and then the shadowing screen is biased downward to the photodiode 168. Any object that blocks the radiation across the viewing surface will cause the IR radiation to fail to reach at least two of the photodiode 68, thereby enabling the position of the object to be detected in one dimension. Figure 16 shows the IR light touch of the present invention. The screen display has the same light deflection mask as shown in Fig. 15. However, the display of Fig. 16 does not require a separate circuit board; instead, the bottom plate of the electro-optical module 162 is larger than The corresponding module in Figure 15. More Specifically, although not shown in FIG. 16, the bottom plate of the electro-optic module is larger than the electro-optical layer itself, so that the peripheral portion of the bottom plate is exposed, and the peripheral portion of the bottom plate has a functional mode corresponding to the whole of FIG. The same LED, s and photodiode ι68. The LED's 166 and photodiode 168 in Figure 16 can be directly mounted on the electro-optic module and adhered to the smashing or other using the z-axis conductive adhesive. Backplane. Deposition techniques using conventional TFT montage layers that have been used to form other connections on the backplane, for example, they are used to connect the backplane column and row drivers to the active matrix backplane column and row electrodes, The electrical connections of the LED's and the photodiode are deposited on the substrate. The photodiode can be constructed to have a single-wire serial interface by which one diode transmits its data to the next, and the next adds its own data to the receiver of the former photodiode. In this way, the number of connections to the Light -30-201232139 polar body array can be minimized.
