[0028] figure 2 It is a schematic partial top view of the touch panel in the first embodiment of the present invention. Please refer to figure 2 , the touch panel 200a includes a substrate 202 and a plurality of sensing pads 210a. In this embodiment, the substrate 202 is, for example, a hard transparent substrate such as a glass substrate. In other embodiments, the substrate 202 may also be a plastic transparent substrate or other flexible transparent substrates. The material of the sensing pad 210a can be a transparent conductive material, such as: indium tin oxide, indium zinc oxide or other suitable transparent conductive materials.

[0029] A plurality of sensing pads 210a are disposed on the substrate 202, wherein two adjacent sensing pads are parallel and oppositely arranged, and each sensing pad 210a includes a middle portion 212 and a plurality of protruding portions 214a. The middle portion 210 a has a plurality of sides 215 , and the plurality of protruding por...

[0036] image 3 It is a schematic partial top view of the touch panel in the second embodiment of the present invention. Please refer to image 3 , the touch panel 200b has most of the components of the touch panel 200a, wherein the same components are denoted by the same reference numerals, which will not be repeated below.

[0037] The main difference between the touch panel 200b and the touch panel 200a is that, in the touch panel 200b, the protruding portions 214b included in each sensing pad 210b are all triangular. At this time, the distance S between two adjacent sensing pads 210b is the distance S between the sides 217 of two adjacent protruding portions 214b.

[0038]Likewise, since the edge of each sensing pad 210b is jagged, and the protruding portions 214b between the two adjacent sides 215 parallel to each other are arranged in a staggered manner, the user will have a blurred vision effect. Therefore, the touch panel 200b can effectively improve the problem of ...

[0040] Figure 4 It is a schematic partial top view of the touch panel in the third embodiment of the present invention. Please refer to Figure 4 , the touch panel 200c has most of the components of the touch panel 200a, wherein the same components are denoted by the same reference numerals, which will not be repeated below.

[0041] The main difference between the touch panel 200c and the touch panel 200a is that, in the touch panel 200c, the protruding portions 214c included in each sensing pad 210c disposed on the substrate 202 are trapezoidal. Based on the same reason, the touch panel 200c can achieve all the technical functions of the above-mentioned touch panel 200a or 200b.

Abstract

The invention relates to a touch-control panel which comprises a base plate and a plurality of sensing pads. The plurality of sensing pads are arranged on the base plate, wherein two adjacent sensing pads are parallel and are arranged opposite to each other; and each sensing pad comprises a middle part and a plurality of projection parts. The middle part is provided with a plurality of side edges, and the plurality of projection parts extend outwards from the plurality of side edges of the middle part. The projection parts between the side edges of two adjacent sensing pads are staggered. The distances of any two adjacent sensing pads are equal.

Description

【Technical field】 [0001] The present invention relates to a touch panel, and in particular to a touch panel with good display uniformity and touch sensitivity. 【Background technique】 [0002] Most of the known touch display modules integrate a touch panel and a display panel. Touch panels can be broadly classified into resistive, capacitive, infrared and ultrasonic touch panels, among which resistive touch panels and capacitive touch panels are the most common products. Since the touch display module can provide a more humanized operation mode, it is gradually favored by the market. [0003] figure 1 It is a schematic partial top view of a known touch panel. Please refer to figure 1 , the touch panel 100 includes a substrate 102 and a plurality of sensing pads 110 . A plurality of sensing pads 110 are disposed on the substrate 102 with a gap S between them. In addition, the touch panel 100 further includes, for example, a plurality of connection lines (not shown) conne...
