FIG. 1 is a schematic diagram of a touch panel module according to an embodiment of the invention. Referring to FIG. 1 , the touch panel module 100 of the present embodiment includes a touch panel 110 and a touch controller 120 . The touch panel 110 is disposed in a touch panel area 210 of the touch panel module 100 , and the touch controller 120 is disposed in a non-touch panel area 220 of the touch panel module 100 . In this embodiment, the non-touch panel area 220 is, for example, a package. A flexible printed circuit (FPC) substrate (not shown) is included.

In other embodiments, the touch panel 110 can be electrically connected to the external circuit by using other methods, and the touch controller 120 can also be disposed in the inactive area of the touch panel 110, that is, the active area 212 on the touch panel 110. Outside the area.

In this embodiment, the touch panel 110 includes a plurality of sensing units 112 for sensing a touch object (not shown). The sensing unit 112 is disposed, for example, in the active area 212 of the touch panel 110. The inactive area of the touch panel 110 includes a fan-out area 214. A plurality of conductive wirings 117 are disposed in the fan-out area 214 or include extensions of the sensing electrodes 113. The touch panel 110 electrically connects the sensing electrode 113 in the sensing unit 112 to the external circuit and the touch controller 120 by using the conductive wiring 117 or the extended sensing electrode 113. It should be noted that, in the exemplary embodiment of the present invention, the number of the sensing units 112, the layout pattern of the internal sensing electrodes 113, and the wiring manner in the fan-out area 214 are for illustrative purposes only, and are not intended to limit the present invention. . In addition, the size of each area in the touch panel module 100 and the size of the sensing unit 112 and the ratio between the two are only for illustrative purposes, and are not intended to limit the present invention.

2 is a schematic diagram showing an electrode pattern of a sensing unit according to an embodiment of the invention. Referring to FIG. 1 and FIG. 2 , the touch panel 110 of the embodiment of FIG. 1 includes a plurality of sensing units 112 for sensing a touch object. FIG. 2 is an embodiment of an electrode pattern of one of the plurality of sensing units 112. In this embodiment, the plurality of sensing units 112 include a second sensing unit 112A. The second sensing unit 112A includes A plurality of first sensing electrodes 113A and a plurality of second sensing electrodes 115A. The area of the first sensing electrode 113A increases along a direction D, and the area of the second sensing electrode 115A decreases along the direction D. In the present embodiment, the direction D is a specific direction from the central area of the active area 212 to the fan-out area 214 of the inactive area.

In this embodiment, the first sensing electrode 113A and the second sensing electrode 115A are staggered. The first sensing electrode 113A and the second sensing electrode 115A respectively have an extended oblique side S1 and S2. In the active region 212, the extended oblique side S1 of the first sensing electrode 113A extends in a specific slope in the other direction opposite to the direction D. The second sensing electrode 115B extends in the active region 212 in a manner of extending the first sensing electrode 113A, and the two are staggered. Therefore, in the present embodiment, the extending directions of both the first sensing electrode 113A and the second sensing electrode 115A are opposite.

In the present embodiment, the first sensing electrode 113A extends from the active region 212 to the fan-out region 214 of the inactive region. The second sensing electrode 115A also extends from the active region 212 to the fan-out region 214 of the inactive region, and separates the first sensing electrode 113A that extends to the fan-out region 214 of the inactive region, as shown in FIG. Therefore, in the embodiment, the area occupied by the first sensing electrode 113A in the inactive area is larger than the area occupied by the second sensing electrode 115A in the inactive area.

In the embodiment, the first sensing electrode 113A is disposed in the non-touch panel area 220 to compensate the linearity of the edge area of the touch panel 110, thereby improving the accuracy of the touch controller 120 for determining the touch position. In other words, in the present exemplary embodiment, at least a portion of the first sensing electrodes 113A are disposed in the non-touch panel region 220. And, another part of the first sensing electrode 113A and the second sensing power All of the poles 115A are the active area 212 disposed in the touch panel area 210 and the fan-out area 214 of the inactive area. Therefore, in the present exemplary embodiment, the second sensing unit 112A includes, for example, a first sensing electrode 113A, a second sensing electrode 115A, an extension of the inactive region, and a second portion disposed in the non-touch panel region 220. A sensing electrode 113A.

Specifically, please refer to FIG. 1 . In the embodiment, the touch controller 120 touches the touch panel module 100 according to the area where the touch object touches the first sensing electrode 113A and the touch object. The ratio of the touched area is determined to determine a touch position of the touch object on the touch panel 110.

Taking the edge region of the touch panel 110 as an example, if the touch object touches the second sensing unit 112A and generates a touch area TA2 thereon, the touch controller 120 can occupy the touch according to the first sensing electrode 113A. The ratio of the touch area TA2 determines the touch position of the touch object on the touch panel 110. For example, in this example, the area where the touch object touches the first sensing electrode 113A and the area touched by the second sensing electrode 115A are, for example, A2 and B2, respectively, so that the touch object touches the first feeling. A ratio of the area A2 of the measuring electrode 113A to the touch area TA2 is substantially A2/(A2+B2). Therefore, the touch controller 120 determines that the touch position of the touch object is the position corresponding to the touch area TA2 occurring in the edge area on the touch panel 110.

Taking the non-display panel area 220 as an example, it is assumed that the touch object touches the second sensing unit 112A, and a touch area TA3 is generated thereon. In this example, the touch position of the touch area TA3 is farther from the active area 212 than the touch area TA2. The area where the touch object touches the first sensing electrode 113A and the area touched by the second sensing electrode 115A are, for example, A3 and B3, respectively, and therefore, the touch object touches the first sensing electrode 113A. A ratio of the area A3 occupying the touch area TA3 is substantially A3/(A3+B3).

It should be noted that, in the exemplary embodiment, the ratio A3/(A3+B3) of the area A3 of the touch object touching the first sensing electrode 113A to the touch area TA3 is substantially larger than the touch object touch. The area A2 of the first sensing electrode 113A occupies a ratio A2/(A2+B2) of the touch area TA2. Therefore, in the present exemplary embodiment, the ratio A2/(A2+B2) of the area A2 of the touch object touching the first sensing electrode 113A and the touch area TA2 is increased along the direction D. In other words, the ratio A2/(A2+B2) can be used as a first threshold value, and when the touch object moves from the fan-out area 214 of the inactive area to the non-touch panel area 220 along the direction D, the object is touched. The ratio A3/(A3+B3) of the area A3 of the first sensing electrode 113A and the touch area TA3 of the touch object module 100 is greater than the first threshold.

In addition, taking the active area 212 as an example, it is assumed that the touch object touches the second sensing unit 112A, and a touch area TA1 is generated thereon. In this example, the position of the touch area TA1 is farther away from the non-touch panel area 220 than the touch areas TA2, TA3. The area where the touch object touches the first sensing electrode 113A and the area touched by the second sensing electrode 115A are, for example, A1 and B1, respectively, and therefore, the area A1 of the touch object touching the first sensing electrode 113A occupies the touch. A ratio of the area TA1 is substantially A1/(A1+B1). Therefore, the touch controller 120 determines that the touch position of the touch object is the position corresponding to the touch area TA1 on the touch panel 110.

In the present exemplary embodiment, the ratio A1/(A1+B1) of the area A1 of the touch object touching the first sensing electrode 113A occupying the touch area TA1 is substantially smaller than the touch object touching the first sensing electrode 113A. The area A2 occupies the proportion of the touch area TA2 A2/(A2+B2). Therefore, in the present exemplary embodiment, the ratio A1/(A1+B1) of the area A1 of the touch object touching the first sensing electrode 113A and the touch area TA1 is increased along the direction D. In other words, the ratio A1/(A1+B1) can be used as a second threshold value, and when the touch object moves from the active area 212 to the fan-out area 214 of the inactive area along the direction D, the touch object touches the first The ratio A2/(A2+B2) of the area A2 of the sensing electrode 113A and the touch area TA2 generated by the touch object module 100 is greater than the second threshold.

Therefore, in the present exemplary embodiment, at least the first sensing electrode 113A disposed in the non-touch panel area 220 touches the object when the touch object moves from the central area of the touch panel 110 to the edge area. The area of the first sensing electrode is significantly increased. Therefore, the ratio of the area touched by the touch object to the first sensing electrode and the touch area generated by the touch object touching the touch panel module may also be significantly changed to compensate the linearity of the edge region of the touch panel 110. , thereby improving the accuracy of the touch controller 120 determining the touch position.

In summary, in the exemplary embodiment of the present invention, the first sensing electrode is disposed in the non-touch panel area. When the touch object moves from the central area of the touch panel to the edge area, the area in which the touch object touches the first sensing electrode is significantly increased. Therefore, the ratio of the area touched by the touch object to the first sensing electrode and the touch area generated by the touch object touching the touch panel module may also be significantly changed to compensate for the linearity of the edge area of the touch panel. Thereby, the accuracy of the touch controller to determine the touch position is improved.
