Description
Technical Field
Exemplary embodiments of the present invention relate to a touch panel. More particularly, exemplary embodiments of the present invention relate to a touch panel capable of recognizing touch coordinates by a small number of driving electrodes even if the size of the touch panel is large.
Detailed description of the related Art
As the types of electronic devices encountered in daily life of people are gradually diversified and the functions of the electronic devices are gradually evolved and complicated, a user interface is urgently needed, and a user can easily learn and intuitively manipulate the electronic devices. Touch screen devices have attracted attention as input devices capable of meeting this demand, and have been widely used in various electronic devices.
The touch sensing device recognizes a user screen touch or gesture as input information. Touch panels of the touch sensing apparatus are classified into resistive, capacitive, ultrasonic, and infrared touch panels according to driving methods thereof. These touch panels, capacitive touch panels, attract a lot of attention due to the ease of multi-touch input.
The structure of the capacitive touch panel is an important factor in more accurately sensing capacitance variation. The touch panel may have a two-layer structure. Here, the touch sensor may be implemented as a series of pixels formed of a plurality of sensing electrode traces (e.g., traces extending in the x-axis direction) and a plurality of driving electrode traces (e.g., traces extending in the y-axis direction) arranged on and crossing the sensing electrode traces. The drive and sense electrode traces may be separated by a dielectric substance such as polyethylene terephthalate (PET) or glass.
Meanwhile, when the size of the touch panel is increased, the number of touch sensing chip channels outputting driving signals for recognizing a touch is increased, which has a problem of increasing sensing time. To reduce the calculation time, aspects of increasing the speed of a CPU, increasing the function of a Digital Signal Processor (DSP), or by dividing a touch panel, etc. have been developed.
However, even when these methods are used, it is difficult to reduce the basic sensing time. For example, assuming that the number of driving lines transmitting driving signals to the touch panel having a size of 24 inches is about 10 times as large as that of the touch panel having a size of 4 inches, the time required to sense the entire area is 10 times or more.

fig. 1 is a schematic plan view illustrating a touch panel 100 according to an embodiment of the present invention.
Referring to fig. 1, a touch panel 100 according to one embodiment of the present invention includes a plurality of driving members and a plurality of sensing members disposed on the driving members. The driving member and the sensing member are formed on different layers from each other. The drive member may comprise an optically transparent conductive material, such as Indium Tin Oxide (ITO). Further, the sensing member may include an optically transparent conductive material, such as Indium Tin Oxide (ITO). In the present exemplary embodiment, the sensing member is formed in a wire shape having a width of a thin wire, so that the sensing member may include a superconducting material, such as gold (Au) or silver (Ag).
An insulating layer (not shown in fig. 1) is arranged between the drive member and the sensing member.
The driving member has a plate shape extending in a low direction and arranged in a column direction. In the present exemplary embodiment, the number of drive members is six. That is, the first, second, third, fourth, fifth and sixth driving members 111, 112, 113, 114, 115 and 116 are formed in a plate shape. Each of the first to sixth driving members 111, 112, 113, 114, 115 and 116 sequentially receives a driving signal from an external device, for example, a touch sensing chip having a capacitance sensing circuit, etc., mounted thereon. In the present exemplary embodiment, the first, second, third, fourth, fifth and sixth driving signals X4 and X5, the first, second, third and fourth driving signals X0, X1, X2, X3, and X5 are sequentially applied to the first to sixth driving members 111, 112, 113, 114, 115 and 116, respectively.
Each of the sensing members has a mesh shape extending in a column direction and arranged in a lower direction. In the present exemplary embodiment, the number of the sensing members is eight. That is, the first sensing member 121, the second sensing member 122, the third sensing member 123, the fourth sensing member 124, the fifth sensing member 125, the sixth sensing member 126, the seventh sensing member 127, and the eighth sensing member 128 are formed in a mesh shape. Each of the first to eighth sensing members 121, 122, 123, 124, 125, 126, 127 and 128 simultaneously transmits a voltage to an external device as a sensing signal in response to the first to sixth driving signals X0, X1, X2, X3, X4 and X5, for example, a touch sensing chip. For example, the first sensing member 121 transmits the first and second sensing signals Y0 and Y1 to the touch sensing chip, and the second sensing member 122 transmits the third and fourth sensing signals Y2 and Y3 to the touch sensing chip. In addition, the third sensing member 123 transmits fifth and sixth sensing signals Y4 and Y5 to the touch sensing chip, and the fourth sensing member 124 transmits seventh and eighth sensing signals Y6 and Y7 to the touch sensing chip. In addition, the fifth sensing member 125 transmits ninth and tenth sensing signals Y8 and Y9 to the touch sensing chip, and the sixth sensing member 126 transmits eleventh and twelfth sensing signals Y10 and Y11 to the touch sensing chip. In addition, the seventh sensing member 127 transmits thirteenth and fourteenth sensing signals Y12 and Y13 to the touch sensing chip, and the eighth sensing member 128 transmits fifteenth and sixteenth sensing signals Y14 and Y15 to the touch sensing chip. The first to sixteenth sensing signals Y0, Y1, Y2, Y3, Y14 and Y15 are simultaneously transmitted to the touch sensing chip.
Each of the first to eighth sensing members 121, 122, 123, 124, 125, 126, 127 and 128 includes a plurality of sub-sensing members. In the present exemplary embodiment, the number of sub-sensing members is two. That is, each of the first to eighth sensing members 121, 122, 123, 124, 125, 126, 127 and 128 includes a first sub sensing member 1211 and a second sub sensing member 1212, which are formed to correspond to each of the first to sixth driving members 111, 112, 113, 114, 115 and 116. The first sub-sensing member 1211 and the second sub-sensing member 1212 are different channels of the touch sensing chip on which the capacitance sensing circuit is mounted. In the present exemplary embodiment, with respect to one driving member (e.g., the first driving member 111), the first sub sensing member 1211 is disposed at an upper region of the first driving member 111 and the second sub sensing member 1212 is disposed at a lower region, overlapping with the first sub sensing member 1211 and the second sub sensing member 1212.
The first sub-sensing member 1211 includes first sensing body portions 1213 and first connection wirings 1214 connected to the first sensing body portions 1213 adjacent to each other in the column direction. The width of first sensing body portion 1213 may be less than or equal to half the width of first drive member 111. The first connection wiring 1214 is arranged at a left side portion of the corresponding sensing member when viewed in a plan view.
The second sub-sensing member 1212 includes a second sensing body part 1215 and a second connection wiring 1216 connected to the second sensing body part 1215 adjacent to each other in the column direction. The width of the second sensing body part 1215 may be less than or equal to half the width of the first driving member 111. The second connecting wiring 1216 is disposed at a right portion of the corresponding sensing member when viewed in a plan view.
In the present exemplary embodiment, the first and second sensing body parts 1213 and 1215 are arranged to correspond to one driving member such that each sensing body part of the corresponding sub sensing member is arranged in the same column region. In fig. 1, each sensing member has a band shape formed in a column direction, and a sensing body portion 1213 of a first sub sensing member 1211 and a sensing body portion 1215 of a second sub sensing member 1212 are arranged on one sensing member in a zigzag shape.
In the present exemplary embodiment, the first sub-sensing member 1211 of the first sensing member 121 transmits the first sensing signal Y0 to the touch sensing chip, and the second sub-sensing member 1212 of the first sensing member 121 transmits the second sensing signal Y1 to the touch sensing chip.
The first sub-sensing member 1211 of the second sensing member 122 transmits the third sensing signal Y2 to the touch sensing chip, and the second sub-sensing member 1212 of the second sensing member 122 transmits the fourth sensing signal Y3 to the touch sensing chip.
in this manner, the first sub-sensing member 1211 of the eighth sensing member 128 transmits the fifteenth sensing signal Y14 to the touch sensing chip, and the second sub-sensing member 1212 of the eighth sensing member 128 transmits the sixteenth sensing signal Y15 to the touch sensing chip.
In fig. 1, first and second sensing body portions 1213 and 1215 are depicted as each having a closed loop shape; however, a partial region on the closed loop shape may be opened. Further, in fig. 1, it is described that each of the first and second sensing body parts 1213 and 1215 has a rectangular shape; however, each of the first and second sensing body parts 1213 and 1215 may have a circular shape or a polygonal shape such as a triangular shape, a pentagonal shape, a hexagonal shape, or the like.
According to the present exemplary embodiment, on the touch panel, there is a two-layer structure, and the driving member transmits the driving signal formed by communicating with the first sub sensing member and the second sub sensing member of different channels. Therefore, one driving member corresponds to two sub-sensing members, thereby reducing the number of driving members. Accordingly, it is possible to reduce the scanning time of touch recognition, which can improve the scanning speed.
Further, the width of the driving member according to the present exemplary embodiment is twice the width of the sub-sensing member, compared to when one driving member is formed to correspond to one sub-sensing member. The width of the drive member is increased to reduce the end-to-end resistance corresponding to the drive member. Since the sensing speed of each channel can be increased, it can sense a touch with high sensitivity.
In addition, it is possible to generate more energy from the driving member to the sensing member to reduce the end-to-end resistance. Further, since the driving member is constituted by a material such as ITO in a plate shape, it is possible to obtain a low end-to-end resistance even in a large size. Therefore, a touch panel capable of recognizing touch coordinates can be realized even if the size of the touch panel is large.
fig. 2 is an exploded perspective schematic view illustrating one embodiment of a touch panel as described in fig. 1.
Referring to fig. 2, the touch panel 200 includes a first base member 210, a plurality of driving members 220 formed on the first base member 210, an insulating layer 230 formed on the driving members 220, and a plurality of sensing members 240 formed on the insulating layer 230. The first base member 210 may comprise film, glass, plastic, or the like.
The driving member 220 may be the first to sixth driving members 111, 112, 113, 114, 115 and 116 described in fig. 1. In addition, the sensing member 240 may be the first to eighth sensing members 121, 122, 123, 124, 125, 126, 127 and 128 described in fig. 1.
According to the present exemplary embodiment, since the driving member and the sensing member are formed on the base member, an additional insulating layer is interposed between the driving member and the sensing member.
Fig. 3 is an exploded perspective schematic view illustrating another embodiment of the touch panel as described in fig. 1.
Referring to fig. 3, the touch panel 300 includes a first base member 310, a plurality of driving members 320 formed on the first base member 310, a second base member 330 formed on the driving members 320, and a plurality of sensing members 340 formed on the second base member 330. The first base member 310 and the second base member 330 may include film, glass, plastic, and the like.
The driving member 320 may be the first to sixth driving members 111, 112, 113, 114, 115 and 116 described in fig. 1. Further, the sensing member 340 may be the first to eighth sensing members 121, 122, 123, 124, 125, 126, 127 and 128 described in fig. 1.
according to the present exemplary embodiment, the driving means is formed on one base member, and the sensing means is formed on the other base member. In this case, the second base member is interposed between the driving member and the sensing member to function as an insulating layer. Therefore, the insulating layer can be omitted as compared with the touch panel described in fig. 2.
Fig. 4 is a schematic plan view illustrating a modified embodiment of the driving member as described in fig. 1.
with respect to fig. 4, each of the driving members 131, 132, 133, 134, 135, and 136 is disposed at the lower layer 130 of the touch panel, has a plate shape, and through holes 1311 are formed thereon to extend in a low direction and to be aligned in a column direction. Each of the driving members 131, 132, 133, 134, 135 and 136 sequentially receives driving signals X0, X1, X2, X3, X4 and X5 from an external device, for example, a touch sensing chip having a capacitance sensing circuit and the like mounted thereon.
The via 1311 is formed to correspond between the sensing body parts 1213 and 1215 (shown in fig. 1) adjacent to each other in the column direction. In fig. 4, it is described that the via holes 1311 are formed in a dot shape; however, the regions connecting the sensing body portions adjacent to each other are removed to form the via holes. Therefore, the through-hole of the line shape can be formed in conformity with the driving member.
Alternatively, the through hole 1311 may extend. For example, regions corresponding to the first sensing body portion 1213 (shown in fig. 1) and the second sensing body portion 1215 (shown in fig. 1) may be removed to form vias therein.
fig. 5 is a schematic plan view illustrating a first modified embodiment of the sensing member as described in fig. 1. In particular, a diamond shape is shown contained within a rectangular shape to define the sub-sense elements.

In the present exemplary embodiment, the number of the sensing members is eight. That is, the first sensing member 421, the second sensing member 422, the third sensing member 423, the fourth sensing member 424, the fifth sensing member 425, the sixth sensing member 426, the seventh sensing member 427, and the eighth sensing member 428 are formed in a mesh shape. Each of the first to eighth sensing members 421, 422, 423, 424, 425, 426, 427, and 428 simultaneously transmits a voltage to an external device, for example, a touch sensing chip.
Each of the first to eighth sensing members 421, 422, 423, 424, 425, 426, 427, 428 includes a plurality of sub-sensing members. In the present exemplary embodiment, the number of sub-sensing members is two. That is, each of the first to eighth sensing members 421, 422, 423, 424, 425, 426, 427, 428 includes a first sub-sensing member 4211 and a second sub-sensing member 4212, which are formed to correspond to each of the first to sixth driving members 111, 112, 113, 114, 115, and 116 (shown in fig. 1).

For example, the width of the first sensing body portion 4213 may be less than or equal to half the width of the first drive member 111 (as shown in fig. 1).
