EMBODIMENT OF THE INVENTION Hereinafter, preferred embodiment of this invention is described with reference to an accompanying drawing.

The present invention provides a portable display device having an effect of viewing at least one screen by interconnecting at least two flat panel displays. As the flat panel display panel, LCD, OLED, FED, PDP, electronic paper, etc. may be used. In addition, when the flat panel has a form, embodiments of the present invention may be applied.

1 to 7 are views illustrating an input device mounted on a frame of a cover type.

In the present invention, a cover frame 24 is provided, and a joint part 8 is formed in the cover frame. 1 is a cover frame 24 having a shape in which one side is opened in a square shape, and the opened part is a joint part 8.

The reason why the joint 8 is present is that the two input devices 200 and 400 have a structure adjacent to each other. In addition, the input device includes a signal transmission line 250c and a connection part 250d. Naturally, the method of coupling the signal transmission line and the connection portion to the input device follows the conventional method.

A groove 24g is provided in the cover frame where the transmission line and the connecting portion are located.

In addition, the input device 200 is mounted on the support part 24c provided in the cover frame 24, and the shape in which the input device 200 is mounted on the cover frame 24 is illustrated in FIG. 2. When the input device 200 is mounted on the cover frame 24, the input device 200 is mounted lower than the height of the surface of the cover frame 24. However, it should not be too different, so the difference should be within 2mm.

In addition, it is provided with a cutout 24b in case the shaft is positioned.

In addition, the cover side wall 24d can be attached to the open part (connection joint part) of the cover frame 24, the state immediately before attachment is FIG. 3, and the state after attachment is FIG. The cover sidewall 24d protects the side of the input device. At this time, the height of the cover side wall 24d may be the same as the height of the cover frame 24, but may be low. In the low case, the difference should not exceed 2mm.

In addition, the thickness of the cover side wall 24d is preferably not more than 2 mm. That is, it may be 0.1mm or 1.5mm but it is better not to exceed 2mm. This is because it is not preferable that the cover side wall 24d is too thick to use two input devices as one input device.

In this case, the two input devices are adjacent to each other within 3 mm or 4 mm. This means that the distance between the input devices 200 and 400 can be up to 3 to 4 mm even if the cover side wall 24d is as thin as 0.3 mm.

5 and 6 are views of the embodiment showing a state in which the cover side wall 24d is integrally formed with the cover frame 24. FIG. When the input device 200 is mounted on the cover frame 24, the input device 200 is mounted lower than the height of the surface of the cover frame 24. That is, the height of the surface of the cover frame 24 is higher than the height of the surface of the input device 200.

In addition, as shown in FIG. 5, the height of the cover sidewall 24d may be the same as the height of the surface of the cover frame 24, and as shown in FIG. 6, the height of the cover sidewall may be lower than the height of the surface of the cover frame 24. . In addition, it may be structurally stable that the height of the side wall of the cover is equal to the height of the input device.

 When the input device 200 is mounted on the cover frame 24 as shown in FIG. 7, the input seam 200 may be mounted in the downward direction of the cover frame 24.

Of course, in some cases, the input device may not be provided in the portable terminal. In this case, the protection plate is mounted at the position where the input device is provided.

8 to 10 are diagrams showing the form in which the input device is mounted on the frame.

As shown in FIG. 8, the frame support part 20c is provided in the frame 20b, and the input device 200 is mounted in the frame support part 20c. Similarly, one side of the rectangular frame 20b has an open shape, and the open portion becomes the joint portion 8. The two input devices 200 and 400 are adjacent to each other through the joint 8.

In addition, mask printing 16d is formed on the input device 200 mounted to the frame 20b. The mask printing 16d has an effect of making the input device opaque, and the mask printing 16 may be formed on a protective plate provided on the input device.

In addition, the mask printing 16d may be black or other opaque colors to make the transparent input device 200 visually prevent the mask printing 16d from forming a pattern, and the mask printing. In 16d, a hole that serves as an outlet for a camera, a speaker, or the like may be located.

9 is a view showing a state in which the input device 200 is mounted to the frame 20b, and FIG. 10 is a view showing a state in which a frame sidewall 24d is provided at the joint 8 of the frame 24. At this time, the thickness of the frame side wall 24d is the same as that of the cover side wall described in the previous embodiment.

Naturally, in the case of a display device which does not need to be provided with the input device 200, a protective plate made of glass or plastic is placed at the position of the input device 200.

11 and 12 are views of an embodiment in which the input seam is mounted in the panel housing.

FIG. 11 is a view illustrating an example in which a cover frame 24 having an input device 200 is mounted on a panel housing 20 on which a display 2 is mounted, and FIG. 12 illustrates a panel housing on which a display 2 is mounted. 20 is a diagram of an embodiment in which the frame 20b provided with the input device 200 is mounted thereon.

On the other hand, when covering the edge on the display 2, it covers the portion except for the seam (8). Therefore, the cover frame 24 has a shape in which one side is opened in a rectangular shape. That is, the cover frame 24 covers the edges of the three sides of the display 2 except for the joint portion. On the other hand, the cover portion 24 is provided with a cutout 24f so that the shaft can be positioned.

The joint part of the cover frame 24 is positioned at the joint part 8 of the display 2, and the joint part 8 of the input device 200 is also located here.

Similarly, when the mask printing 16d of the input device 200 blocks the edge of the upper portion of the display 2, the edges of the three sides except for the seam are blocked.

Naturally, the seam of the frame 20b is mounted on the seam 8 of the display 2, and the seam of the input device 200 is also mounted.

In addition, in the present invention, when the cover frame 24 or the frame 20b is mounted to the panel housing 20, it is natural that the cover frame 24 or the frame 20b is mounted with grooves, protrusions, or screws. Since the method is based on the method, it is not shown in the present invention.

13 to 17 illustrate an embodiment in which an input device is coupled to an upper end of a panel housing.

FIG. 13 illustrates a case in which the display 2 is mounted on the sidewalls of the panel housings 20 and 40, and the input devices 200 and 400 are mounted thereon. In addition, the protection plate 14 is attached to the side surfaces of the joints of the display 2 and the input device 200 and the 400.

The protective plate 14 may be thin in the form of a film, but may be within 0.01 mm, but may maintain a thickness from 0.2 to 0.3 mm. Naturally, the protection plate 14 needs to have a certain color.

In addition, the distance between the display 2 and the input device 200 may be within 0.1 mm to 2 mm.

And with the shield in between, the distance between the input devices is 0.02 mm and the distance between the displays is 0.02 mm.

14 and 15 are diagrams of an embodiment in which a cover sidewall 24d is provided on the side of the input device 200 or 400. The cover side wall 24d is formed integrally formed or attached to the cover frame 24 or the frame 20b as in the embodiment of FIGS. 3 to 6 and 10.

FIG. 14 illustrates a case in which the cover sidewall 24d blocks both the sidewall of the display 2 and the sidewalls of the input device 200 and 400, and only the sidewall of the input device 200. That is, it is natural that the cover sidewall 24d may be formed to be somewhat long to block the side of the display 2.

14 and 15 illustrate an embodiment in which the cover side wall 24d is connected to the cover 24 or the frame 20b, but extends from the side walls of the panel housing 20 and 40 to display 2 or input. Of course, it can block the side of the device 200.

In addition, the thickness of the cover side wall 24 may be the same as the side wall of the panel housing, but may be small. Therefore, if it is small, it can exceed 0.2mm, and if it is the same, it will not exceed 1.5mm which is the thickness of the panel housing normally. Of course, it does not have to be thinner than the panel housing thickness.

In this case, when the two panel housings 20 and 40 are unfolded, it means that the distance between the two displays 2 and 4 should be within a maximum of 3 mm. In addition, the maximum distance between the displays 2 and 4 is 3 mm even if the thickness of the cover side wall 24 or the panel housing side wall becomes thin (for example, thinly formed to 0.3 mm). Means that the distance between them can be 3mm.

16 and 17 illustrate a case where the distance between two displays 2 and 4 is greater than the distance between two input devices 200 and 400.

FIG. 17 illustrates a case in which the thickness of the side wall portion 20a of the panel housing 20 which blocks the side of the display 2 is thinner than that of the other part of the panel housing. In addition, the input devices 200 and 400 are provided on the upper ends of the displays 2 and 4, and the protection plate 14 is provided on the side of the input device. At this time, the thickness of the protective plate 14 is formed thinner than the side wall portion (20a).

FIG. 17 is a view of an embodiment in which a stepped sidewall 24d is provided, of course, a stepped sidewall 24d is not formed in the lid 24 or the frame 20b and extends in the sidewall of the panel housing 20. Of course it can be formed.

In FIG. 17, only portions that block the sides of the input devices 200 and 400 are formed in the cover 24 or the frame 20b, and portions that block the sides of the display 2 and 4 are panel housings 20 and 40. Of course, it can be formed extending to the side wall.

That is, the portion blocking the input device 200 or 400 or the side surface of the display may be the protection plate 14, the cover side wall 24d, or may be on an extension line of the side walls of the panel housing 20 and 40. . In addition, such a structure is not important, but the distance between the input devices 200 and 400 and the distance between the displays 2 and 4 is important. Therefore, the present invention is limited to the number for the thickness.

18 and 19 are views illustrating a panel housing in which a cover or a frame is mounted.

FIG. 18 illustrates a case in which two covers 24 are mounted and two input devices 200 and 400 are also mounted. FIG. 19 is a view showing an embodiment in which two frames 20b and 40b are mounted.

Displays 2 and 4 are mounted adjacent to each other in the two panel housings 20 and 40, and input devices 200 and 400 are mounted adjacent to each other on the display.

In addition, the panel housings 200 and 400 may be folded and unfolded by the shaft 6.

20 to 22 are enlarged views illustrating a joint portion of a touch panel and a display.

20 is an example of a resistive input device, in which two substrates (transparent plastics) coated with transparent electrodes are bonded to each other.

In the joint portion 8, the distance M between the bus 250n and the partition wall is within 1 mm, and the thickness L of the partition wall 250f is also within 0.01 mm to 1 mm. Naturally, the distance M may be 0 mm, of course.

In this case, the barrier rib is mainly used as a bonding means used to couple the transparent electrodes to each other or to couple other plates in the input device. The bus 250n is a signal transmission electrode line reading the resistance value.

Therefore, in the seam 8, the distance between the electrode line 250n and the boundary 250g of the input device 200 is less than 2 mm. Alternatively, the distance from the boundary of the active area 250a to the boundary 250g of the input device 200 is within 2 mm. Here, the active area is an area where the conductor is coated to sense the pressure on the surface of the input device, and thus also means an area for inputting information.

Of course, the boundary 250g of the seam 8 and the boundary of the partition 250f do not need to coincide completely, and it is natural that the partition 250f may be provided within a range of 0.5 mm from the boundary 250g. . In this case, the maximum value between the electrode line 250n and the boundary line 250g is 2.5 mm, and the maximum value from the boundary of the active area 250a to the boundary line 250g is also 2.5 mm. At this time, it is obvious that the maximum value can be maintained even if the size of the partition is small.

In addition, in the present invention, the input device is not necessarily limited to the capacitive type and the resistive film type, and is composed of a flat plate made of plastic or glass, and means all common methods of inputting information through a plane. In all conventional input devices, the seam is designed so that the active area can be located within a certain value from the boundary line.

21 is a structure in which no electrode line or the like is provided between the boundary 223a of the active area 223 and the input device boundary 250g in the capacitive manner. The distance from the active area boundary 223a to the input device boundary 250g is within 3 mm.

FIG. 22 is a view illustrating a display at a seam. In the present invention, two screens are connected to each other to minimize a seam, and thus a display for reducing a seam should also be designed.

When there is a pixel 2n closest to the seam 8 as shown in the figure, the distance J between the adjacent pixel 2n and the partition wall 2f is within 1 mm, and there is no problem even if the J value is zero.

In addition, the thickness K of the partition 2f is also within 0.8 mm and at least 0.01 mm. Therefore, the distance from the pixel 2n closest to the seam to the edge boundary 2g of the display 2 and 4 is within 2 mm. Of course, even if the partition 2f is thinner (e.g., 0.1mm), the distance between the adjacent pixel and the display edge boundary 2g can be 2mm.

Here, the partition wall 2f refers to a boundary between the inside and the outside of the two substrates forming the display panel. That is, a sealant of an adhesive material component can be used as a partition. The substrate may be etched into a partition wall to be used as a partition wall. In this case, when the display substrate is made of glass, the glass material may be a partition wall, and when the substrate is made of metal, the metal material may be the partition wall.

On the other hand, the displays 2 and 4 are usually mounted on the chassis 16, which is made of metal such as aluminum or alloy. In addition, a display module (Module) is configured by attaching a display and a display driver or a backlight component (when the display is an LCD) to the chassis.

In this case, the chassis does not necessarily need to be made of a metal material, but may be in the form of an appliance made of plastic resin. It is also possible to mix metal and plastic appliances. That is, in the present invention, the chassis collectively refers to the structure on which the display component is mounted.

In addition, the thickness of the chassis 16 in the joint part 8 shall be 0.01 mm or more and 1 mm or less. However, the maximum thickness of the most efficient chassis 16 does not exceed 0.5 mm. Therefore, the distance from the seam 8 to the boundary between the nearest pixel 2n and the chassis 16 is within a maximum of 2.5 mm.

Of course, the boundary between the display boundary line 2g and the partition wall 2f does not need to be completely coincident with the seam 8, and it is natural that the partition wall 2f may be provided within a range of 0.5 mm from the boundary line 2g. Do. In this case, the distance from the closest pixel 2n to the boundary of the chassis 16 in the seam 8 is at most 3.0 mm.

That is, in the present invention, the non-display area of the seam is the sum of the J value, the K value, and the thickness of the chassis, and the value is 3.0 mm at maximum, and the value is maximum when the two displays are interconnected. Of course, this value is of course excluded from the thickness of the protective plate or sidewall.

In this case, the chassis 16 is not necessarily provided in the case of the side surfaces of the joints 2 and 4. Instead of the chassis 16 may be a simple protective film.

In addition, it is obvious that the design structure of FIG. 22 may be applied to all display devices having the form of a flat panel display device. In other words. When the flat panel display is applied, the distance from the pixel of the seam to the display boundary may be applied to an embodiment of the present invention.

23 to 27 show a drive block diagram of the display device of the present invention.

Fig. 23 is an overall block diagram, in which the central processing unit 105 is control means for controlling the overall operation of the portable display device of the present invention. The ROM 121 controls an execution program of the display device, the RAM 122 stores data generated when the program is executed, and the EPI ROM 123 stores data needed by the user and data necessary for processing the program. Keep it.

The R / F unit 124 is a radio frequency, tunes to an RF channel, amplifies an input voice signal, and converts an RF signal received from an antenna into an intermediate frequency signal. The input unit 100 includes various input devices, numeric keys, menu keys, and selection keys.

There are display driving circuits (2a) (4a) for driving the display by the output of the central processing unit 105, and the first and second displays (2) (4) for displaying information on the screen according to the output signal of the driving circuit. There is.

In addition, the gravity sensor 235 is provided to determine whether the two displays 2 and 4 are positioned vertically or horizontally. That is, the central processing unit 105 determines whether the two displays 2 and 4 are positioned vertically or horizontally by the input signal of the gravity sensor 235. The determination of the top, bottom, left and right drives the gravity sensor and determines the output of the gravity sensor by a predetermined program method.

And, since it is a judgment as to whether the screen is positioned up or down or left and right, the gravity sensor makes a judgment about a 90-degree rotational movement. This can be done using a conventional gravity sensor.

The CPU also controls the first and second input devices 250-1 and 250-2 through the first and second input device drivers 1401-1 and 140-2. That is, since two input devices 250-1 and 250-2 are present, two input device drivers 140-1 and 140-2 are also present to control corresponding input devices.

The input devices 250-1 and 250-2 shown in the block diagram of FIG. 23 are the same as the input devices 200 and 400 shown in another view of the present invention.

24 to 27 show partial detailed block diagrams.

In the present invention, two displays 2 and 4 are provided, and two input devices 250-1 and 250-2 are also provided, and an input device is provided on the top of the display.

Therefore, the present invention is provided with a control unit for controlling the two display (2) (4), and also controls the signals output from the two input devices (250-1) (250-2).

As shown in FIG. 24, the central processing unit or the main body control unit 105 includes a controller 110, a memory 120, a time controller 125, a display driver 130, and an input device driver 140. Is provided.

That is, each component that functions as the controller 110, the memory 120, the time controller 125, the display driver 130, and the input device driver 140 is all provided in the main body controller 105 to provide a single component. It can be prepared as.

The display driver 130 divides the screen and sends data to the first display 2 and the second display 4, respectively. In addition, the input device driver 140 also corrects and adjusts signals output from the first input device 250-1 and the second input device 250-2, respectively.

In addition, in order to display the screen of the display (2) (4), the source (2b) (4b) section for providing a data signal and the gate section (2c) (4c) for providing a line selection signal Will be present.

25 and 26 illustrate the display driver 130, and the driver 130 includes a column data processor 131 and a row data processor 132.

At this time, a method of dividing a display screen into two may be divided into source data and a gate signal.

As shown in FIG. 25, the column data processing unit 131 for supplying source data (data signal on the screen) supplies the same data signal to the first display 2 and the second display 4, and supplies a low data processing unit (Gate signal). In 132, the signal is divided and supplied to the first display 2 and the second display 4.

For example, when the number of pixels of the entire screen is 320 X 240 dots, the dual data (Source, Column) line (320) and 320, the selection signal (Gate, Row) lines can be said to be 240. .

In this case, the first display 2 and the second display 4 have 320 data lines and 120 select signal lines, respectively. That is, the data line is not divided on the phone screen, but the selection signal line is divided.

In this case, the degree of division is usually 1: 1 (the value of each line is 120 lines if the entire screen is 240 lines), but the ratio may be adjusted according to the terminal design. For example, various ratios can be adjusted to the 140 lines of the first display and the 100 lines of the second display.

In the selection signal line, since only the selection signals of the same waveform are repetitive and sequentially transmitted, only the lines are divided and the same signal is transmitted by the control of the time controller 125.

In the block diagram of FIG. 26, the raw data processing unit (Gate signal) 132 supplies the same data signal to the first display 2 and the second display 4, and supplies the source data (data signal on the screen). The supplied column data processing unit 131 divides and sends a signal to the first display 2 and the second display 4, respectively.

That is, in the case of 320 X 240 Dot, as in the description of FIG. 25, the number of gate lines in the first display 2 and the second display 4 is 240, and the first display 2 and the second display are the same. The number of source lines of the two display 4 becomes 160, respectively.

That is, if the data source line is 320 lines in the entire screen before dividing, a signal is sent to the first display 2 from the first line to the 160th line, and the first to the 320th line from the 161st line to the 320th line. 2 will send a signal to the display 4. The full screen data information before division stored in the memory 120 is divided by the controller 110 and the time controller 125.

Of course, also at this time, the data line of the first display 2 and the data line of the second display do not necessarily need to be divided into 1: 1. Naturally, it can be divided into various ratios such as 2: 3, 10: 6, 6: 4, etc. That is, the capacity of the first display 2 and the second display 4 may not necessarily be 1: 1 depending on the terminal design.

27 is a detailed view of the input device driver 140.

First, the calibration function performing unit 141 performs a calibration function on the input device 250 when the system is first operated. The panel signal corresponding to the correct coordinate value for the input device 250 is selected according to the calibration function performed by the calibration function performing unit 141.

That is, the input device 250 signal corresponding to the coordinate value is selected according to the resolution of the display 2 and 4 (the number of lines of the source and the gate), and the selected signal is provided to the controller 110. Accordingly, the controller 110 stores and manages the coordinate values corresponding to the panel signal.

The average value detection frequency adjusting unit 143 adjusts the average value detection frequency for the panel signal output from the input device 250 based on the screen resolution information of the display device 2 or 4 provided from the control unit 110. When the screen resolution is changed to high resolution, the average number of times of detection is adjusted to be larger than a previously set value. On the contrary, when the screen resolution is changed to a low resolution, the average number of times of detection is adjusted to be smaller than a previously set value.

In addition, the average value detector 142 detects the average value of the panel signal transmitted from the input device 250 based on the average value detection frequency adjusted by the average value detection frequency adjustment unit 143. The detected average value is transmitted to the adjusted panel signal generator 144.

The adjusted panel signal generator 144 uses the average information of the position information of the display screen changed by the changed screen resolution or the virtual scroll of the display apparatus 2 or 4 provided from the controller 110 and the currently input panel signal. To generate an adjusted panel signal.

At this time, in the present invention, the first input device 250-1 and the second input device 250-2 are provided. Therefore, the input device driver 140 controls the signal of the first input device 250-1. Signal control of the second input device 250-2 is performed.
