The touch electrode structure 101S includes a plurality of first touch units. 110 and a plurality of second touch units 120. The first touch unit 110 and the second touch unit 120 are arranged in an array. For example, the first touch unit 110 and the second touch unit 120 in FIG. 1 are arranged in a rectangular array of 5 by 8, but not limited thereto. In this embodiment, each of the first touch units 110 in the same row is alternately spaced from the second touch units 120, and each of the first touch units 110 in the same column is The second touch units 120 are alternately arranged at intervals. In other words, at least one first touch unit 110 is disposed between two adjacent second touch units 120 in the same row (or the same column), and at least one second touch unit 120 is disposed on the same line. (or in the same column) between two adjacent first touch units 110. In addition, in the embodiment, the first touch units 110 in the same row are electrically connected to each other to form a plurality of first axial electrodes 110A, and at least a portion of the second touch units 120 are along an extending direction. D1 is electrically connected to at least one second touch unit 120 located in different rows and different columns to form a plurality of second axial electrodes 120A.

Further, in the embodiment, the first touch unit 110 and the second touch unit 120 in the same row are alternately arranged in a row direction X, and each of the first touch units 110 and the first row in the same row The center points of the two touch units 120 are on the same straight line in the row direction X. The first touch unit 110 and the second touch unit 120 in the same column are alternately arranged along a column Y direction, and the center points of the first touch units 110 and the second touch units 120 in the same column are Located on the same line in the column direction Y. In addition, the first touch units 110 in the same column are electrically separated from each other, and the second touch units 120 in the same column are electrically separated from each other. In general, each of the first touch units 110 is electrically connected to the first touch unit 110 adjacent to the row direction X to form a plurality of first axial electrodes 110A, and at least a portion of the second touch units 120 is electrically connected to the second touch unit 120 adjacent to the extending direction D1 to form a plurality of second axial electrodes 120A. Wherein, between the first axial electrodes 110A, between the second axial electrodes 120A, and any of the first axial electrodes 110A and any of the second axial electrodes 120A are electrically separated from each other.

Furthermore, the row direction X is substantially perpendicular to the column direction Y, but is not limited thereto. The extending direction D1 and the column direction Y have an angle A1, the angle A1 is substantially less than 90 degrees, and the angle A1 is preferably about 45 degrees, but is not limited thereto. For example, at least a portion of the second touch unit 120 in the even column is electrically connected to at least one second touch unit 120 in an odd column of the adjacent row along the extending direction D1, and at least a portion of the second touch in the odd column. The control unit 120 is electrically connected to the at least one second touch unit 120 of the even-numbered columns in the adjacent row in the extending direction D1, but is not limited thereto. That is, at least a portion of the second touch unit 120 is electrically connected in an oblique manner in a direction D1 different from the row direction X and the column direction Y.

The first touch unit 110 and the second touch unit 120 of the present embodiment preferably use a force sensitive conductive material or a heat sensitive conductive material. Thereby, the characteristic principle of the resistance change occurs when the force-sensitive conductive material or the heat-sensitive conductive material is triggered, so that the first embodiment can detect the resistance change of the first axial electrode 110A and the second axial electrode 120A before and after the touch. Then, the positioning of the touch point is performed.

As shown in FIG. 1 , the touch panel 101 of the embodiment may further include a first bus 150 and a second bus 160 . The first bus 150 is electrically connected to one ends of the first axial electrode 110A and the second axial electrode 120A, and the second bus 160 is electrically connected to the other ends of the first axial electrode 110A and the second axial electrode 120A. For example, the first bus 150 can be disposed on the upper side and the right side of the touch panel 101, and is located in the rightmost second touch unit 120 and located in the rightmost column. The first touch unit 110 is electrically connected to the second touch unit 120 and the first touch unit 110 located in the second column on the right side. In contrast, the second bus 160 can be disposed on the lower side and the left side of the touch panel 101, and is located at the lowermost second touch unit 120. The first touch unit 110 in the leftmost row is electrically connected to the second touch unit 120 and the first touch unit 110 in the second column on the left side. However, the present invention is not limited to the above-described setting manner.

Thereby, the back end controller (not shown) electrically connected to the touch panel 101 can determine the position where the touch panel 101 is touched by the change of the output signal RS. It should be noted that the first bus 150 of the embodiment preferably transmits the touch signal to the first axial electrode 110A and the second axial electrode 120A at the same time, and the second bus 160 simultaneously detects all the first axial electrodes. The output signal RS of the 110A and the second axial electrode 120A is not limited thereto.

To further describe the touch detection and positioning manner of the touch panel 101 of the present embodiment, please refer to FIG. 2 to FIG. 4 at the same time. FIG. 2 is a schematic diagram of a touch detection method of the touch panel of the embodiment. FIG. 3 is a schematic diagram of touch detection of the touch panel of the present embodiment in a multi-touch state. FIG. 4 is a schematic diagram of touch detection of the touch panel of the present embodiment under another multi-touch condition. As shown in FIG. 2, when a touch object such as a finger presses the first touch unit 110 or the second touch unit 120, the resistance change of the first touch unit 110 or the second touch unit 120 located at the touch center will be The maximum resistance change from the touch center is smaller, and the resistance change of the corresponding first axial electrode 110A or second axial electrode 120A before and after the touch can be further obtained according to the change of the resistance.

Further, this embodiment assumes that different resistors are designed in the third-order position. The first touch unit 110 or the second touch unit 120 corresponding to the touch center can be defined as a first step, and the resistance change is ΔR1; the first touch unit 110 is closer to the touch center point. Or the second touch unit 120 (also referred to as the first touch unit 110 or the second touch unit 120 adjacent to the touch center point or adjacent to the touch center point) may be defined as a second order, and the resistance thereof changes. The first touch unit 110 or the second touch unit 120 adjacent to the touch center point and different in a row may be defined as the third order, and the resistance change is ΔR3. ΔR1 is substantially greater than ΔR2, and ΔR2 is substantially greater than ΔR3. In this embodiment, the resistance change of different levels is defined only by the third-order position, and the resistance change outside the third-order position is ignored in the embodiment to facilitate the following examples. Of course, according to the actual design requirements, it is also possible to define the resistance change of more order positions to make more accurate calculation judgment, which is not limited by this creation.

Next, it is assumed that the uppermost one of the directions shown in FIG. 3 and FIG. 4 is defined as the first line and the leftmost side is defined as the first column. When the touch point P1 and the touch point P2 shown in FIG. 3 respectively touch the second touch unit 120 of the second row and the fourth column in the same third row, and the touch as shown in FIG. 4 When the point P3 and the touch point P4 respectively touch the second row and the fourth row of the second touch unit 120 in the same third column, the maximum resistance change obtained under the touch conditions of FIG. 3 and FIG. 4 Both are the sum of ΔR1 and triple ΔR3 and are all reacted by the second axial electrode 120A corresponding to the fourth row and the sixth row of the first column, but the touch conditions of FIGS. 3 and 4 can still pass. The other first axial electrodes 110A and/or the second axial electrodes 120A have different resistance changes to perform multi-touch positioning, for example, the first axial electrodes corresponding to the third row of the first row are generated. The change in resistance is different.

It should be noted that, since the present embodiment is designed by using a force-sensitive conductive material, if the resistance changes of the first axial electrode 110A and the second axial electrode 120A are calculated, if different touch points are present, If the overlap is defined in the defined third-order position range, then the weight The resistance values of the first touch unit 110 or the second touch unit 120 corresponding to the stack may have a multiplication effect, which depends on the electrical characteristics of the actual circuit, and the embodiment is calculated by, for example, twice the effect. For example, the touch points P1 and P2 are formed on the second touch unit 120 in the second row of the third row, that is, the overlap phenomenon of the resistance change of the third-order position is formed, and thus the resistance of the associated second axial electrode 120A is calculated. When the change occurs, the resistance change of the second touch unit 120 corresponding to the overlap is calculated by twice ΔR3.

To further specifically illustrate the structural relationship between the first axial electrode 110A and the second axial electrode 120A in FIG. 1, please refer to FIG. 5 together. FIG. 5 is a partially enlarged schematic view showing a touch panel according to an embodiment of the present invention. As shown in FIG. 5, the shape of the first touch unit 110 and the second touch unit 120 in this embodiment may be a rectangle or other suitable shape. In addition, the touch electrode structure further includes a plurality of first connecting lines 130, a plurality of second connecting lines 140, and a plurality of insulating blocks 170. The first touch line 110 of each of the first axial electrodes 110A is electrically connected through the first connection line 130, and the second touch unit 120 of each of the second axial electrodes 120A is between Electrical connections are made through the second connection line 140.

The insulating block 170 is disposed between the first connecting line 130 and the second connecting line 140 for electrically isolating the first axial electrode 110A and the second axial electrode 120A. In this embodiment, the second connecting line 140, the insulating block 170, and the first connecting line 130 are sequentially arranged. In other embodiments, the first connecting line 140 and the insulating block 170 may be sequentially used. The arrangement of the second connection line 130 is designed. The first connection line 130 or the second connection line 140 may be formed of the same material as the first touch unit 110 and the second touch unit 120, but is not limited thereto. In other preferred embodiments of the present invention, the first connecting line 130 and the second connecting line 140 may be formed by using other conductive materials having lower resistance, which may reduce the impedance and improve the sensitivity of the touch panel. It is worth noting that due to this In the embodiment, the first connecting line 130 bypasses the second touch unit 120 in the row direction X to connect the two adjacent touch units 110. Therefore, each of the second touch units 120 can perform touch sensing. It is not affected by the first connecting line 130, and the insulating block 170 only needs to separate the first connecting line 130 from the second connecting line 140, so the area of the insulating block 170 is small.

Please refer to Figure 6. FIG. 6 is a partially enlarged schematic view showing a touch panel of another embodiment of the present invention. As shown in FIG. 6, the difference between this embodiment and the above embodiment of FIG. 5 lies in the arrangement positions of the first connecting line 130 and the insulating block 170. In the touch electrode structure 102S of the touch panel 102 of the present embodiment, the first connection line 130 in the row direction X is designed to electrically connect the adjacent two first touch units 110 across the second touch unit 120. The insulating block 170 is disposed between the second touch unit 120 and the first connecting line 130 for electrically isolating the first axial electrode and the second axial electrode. In addition to the positions where the first connecting line 130 and the insulating block 170 are disposed, the touch panel 102 of the present embodiment has similar material characteristics, setting manners, and touch detection methods to the selected embodiment of FIG. 5, so This will not be repeated here.

The different embodiments of the touch panel of the present invention will be described below, and the following description is mainly for the sake of simplification of the description, and the detailed description of the same parts will not be repeated. In addition, the same components in the various embodiments of the present invention are denoted by the same reference numerals to facilitate the comparison between the embodiments.

Please refer to Figure 7. FIG. 7 is a schematic view showing a touch panel of a second embodiment of the present invention. As shown in FIG. 7 , the difference from the first embodiment is that in the touch electrode structure 201S of the touch panel 201 of the embodiment, the first touch unit 110 or the second touch is fully disposed in the same column. The control unit 120 is not alternately disposed by the first touch unit 110 and the second touch unit 120. Specifically, in the embodiment, the first touch unit 110 is only disposed in an even column, and the second touch Unit 120 is only placed in odd columns. As a result, at least part of the second touch unit 120 of the embodiment is electrically connected to the second touch unit 120 adjacent to the extension direction D2, wherein the extension direction D2 and the column direction Y have an angle A2. The angle A2 is substantially less than 90 degrees and greater than 45 degrees, but is not limited thereto. For example, at least a portion of the second touch unit 120 located in the odd column is electrically connected to at least one second touch unit 120 in an odd column of the adjacent row along the extending direction D2. In addition to the position of the first touch unit 110 and the second touch unit 120 and the electrical connection between the second touch units 120, the touch panel 201 and the touch electrode structure 201S of the present embodiment are The material characteristics, the setting manner, and the touch detection manner are similar to those of the first embodiment described above, and thus are not described herein again.

Please refer to Figure 8. FIG. 8 is a schematic diagram of a touch panel of a third embodiment of the present invention. As shown in FIG. 8 , the difference between the present embodiment and the second embodiment is that, in the touch electrode structure 202S of the touch panel 202 of the present embodiment, the first touch unit 110 is only disposed in an odd column. The second touch unit is set only in an even column. Thereby, at least a portion of the second touch units 120 located in the even columns are electrically connected to the at least one second touch unit 120 in the even rows of the adjacent rows along the extending direction D2. In addition to the positions of the first touch unit 110 and the second touch unit 120, the touch panel 202 and the touch electrode structure 202S of the present embodiment have the material characteristics, setting manners, and touch detection methods of the remaining components. The second embodiment described above is similar, and therefore will not be described again.

The present invention also provides a touch panel detection method, which can be applied to the touch position detection of the touch panel provided by the above embodiments. Hereinafter, only the touch panel of the embodiment corresponding to FIG. 1 will be described. Please refer to FIG. 9. FIG. 9 is a schematic diagram of a method for detecting a touch panel according to a preferred embodiment of the present invention. As shown in FIG. 1 and FIG. 9 , the method for detecting a touch panel of this embodiment includes the following steps. First, step S1 is performed to provide a touch panel 101. Wherein, the touch panel 101 The touch electrode structure 101S includes a plurality of first touch units 110 and a plurality of second touch units 120. The first touch unit 110 and the second touch unit 120 are arranged in an array. Each of the first touch units 110 and the second touch units 120 are alternately spaced apart from each other, and the first touch units 110 in the same row are electrically connected to each other to form a plurality of first axial electrodes 110A, and At least a portion of the second touch unit 120 is electrically connected to at least one second touch unit 120 located in different rows and different columns along an extending direction D1 to form a plurality of second axial electrodes 120A. The features of the touch panel 101 of the present embodiment have been described in detail above, and thus are not described herein again.

Then, step S2 is performed to simultaneously drive all of the first axial electrodes and the second axial electrodes 120A, and simultaneously detect the output signals RS generated by the first axial electrodes 110A and the second axial electrodes 120A. Then, step S3 is performed, and the touch position coordinates are calculated according to the output signals RS.

As shown in FIG. 3 and FIG. 4 , the first touch unit 110 or the second touch unit 120 on the touch panel 101 is touched. When touched, it will correspond to a unique combination of resistance changes of the first axial electrode 110A and the second axial electrode 120A. In a detection calculation embodiment, by comparing the resistance changes of the first axial electrode 110A and the second axial electrode 120A with a data table, it can be obtained which axial electrode the actual touch point occurs. Which touch unit. Specifically, the combination of the resistance changes of the corresponding first axial electrode 110A and the second axial electrode 120A can be separately measured and stored in advance for different touch positions and different touch states. The data table is formed such that the various touch inputs uniquely correspond to a combination of resistance changes of the first axial electrode 110A and the second axial electrode 120A. In this way, when the touch actually occurs, the foregoing step S3 is compared according to the combination of the output signal RS detected in step S2 and the resistance change in the preset data table. In comparison, the position of the actual touch point can be obtained. It should be noted that, in this embodiment, the comparison of the resistance changes represented by the output signal RS can be simply performed for all the first axial electrodes and the second axial electrodes. In addition, it is also possible to determine a specific region where the touch point occurs by the resistance change represented by all the output signals RS, and only the first axial electrode 110A and the second axial electrode 120A corresponding to the specific region. In comparison, since it is not necessary to compare all of the first axial electrode 110A and the second axial electrode 120A one by one, the calculation speed can be increased.

Another detection calculation embodiment is implemented by deleting the method. In the specific design, according to the magnitude of the resistance change represented by the output signal RS, the range that the touch point may occur is reduced from large to small, so as to narrow the surface range to the point range, thereby obtaining where the actual touch point occurs. Which touch unit of an axial electrode. In other words, first, the area of the first axial electrode 110A or the second axial electrode 120A that generates the maximum resistance change on the touch electrode structure is calculated, and then the first axial electrode 110A that produces the second largest resistance change is calculated. Or the relative positional relationship of the second axial electrode 120A to the first axial electrode 110A or the second axial electrode 120A that generates the maximum resistance change to filter and reject the first occurrence of the touch point in the region. The touch unit 110 or the second touch unit 120, and so on. When each of the first touch unit 110 or the second touch unit 120 on the touch panel 101 of the present invention is touched, it will correspond to a unique set of first axial electrodes 110A and The resistance change of the two-axis electrode 120A is combined, so that the position of the actual touch point can be obtained according to this deletion method. The deletion method is exemplified by the change in resistance generated by the touch points shown in FIGS. 3 and 4. First, as shown in FIG. 3 and FIG. 4, it is known that the maximum resistance change is generated by the second axial electrode 120A corresponding to the sum of the output signal RS being ΔR1 and three times ΔR3, that is, in the fourth row and the sixth row and in the direction of D1. The second axial electrode 120A, it can be seen that the touch point is located on the fourth and sixth rows and along the second axial electrode 120A in the direction of D1, and the touch point may only be FIG. The touch point P1 and the touch point P2 are shown or the touch point P3 and the touch point P4 shown in FIG. 4, so that only one of the two situations needs to be excluded to determine the touch point position. Thereafter, the first axial electrode 110A or the second axial electrode 120A with the second largest resistance change is calculated, and if the second largest resistance change is the first axial electrode 110A located in the third row (as shown in FIG. 3), It is determined that the touch points are P1 and P2, that is, the touch point positions are the third row and the third row and the fourth column, and if the second largest resistance changes to the first axial electrodes 110A located in the second, third and fourth rows (As shown in Figure 4), it can be determined that the touch points are P3 and P4, that is, the touch points are located in the second row, the third column, and the fourth row and the third column, respectively. Compared with the previous detection calculation embodiment, the embodiment does not need to store the data table in advance, and does not need to perform the comparison process, and directly calculates the position of the touch point by means of screening and culling.

In summary, the touch panel and the touch electrode structure of the present invention are composed of a first touch unit and a second touch unit arranged in an array manner, and are adjusted by an electrical connection design to be made by the same line. The first axial electrode electrically connected to the first touch unit is formed to be smaller than the second axial electrode electrically connected by the second touch unit in different rows and different columns in an extending direction. The angle of 90 degrees. In this way, the first axial electrode and the second axial electrode can be simultaneously driven and scanned, and multi-touch detection can be realized by calculating the corresponding resistance change of each axial electrode before and after the touch, and effectively improving The speed of the touch response.

Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the present invention, and any person skilled in the art can make any changes without departing from the spirit and scope of the present invention. And the retouching, therefore, the scope of protection of this creation is subject to the definition of the scope of the patent application attached.
