Problems solved by technology

[0003] However, if figure 1 As shown, the touch screen in the prior art includes touch electrodes arranged horizontally and vertically, the horizontal touch electrodes 01 and the vertical touch electrodes 02 are connected to signal lines in the edge area, and all the signal lines 03 are located at the same layer, and formed by one manufacturing process. Due to the limitation of the manufacturing process, the width of the signal line 03 cannot be further reduced, so that the width of the routing area is the sum of the widths of the routing areas of the above two signal lines, that is The overall width of the wiring area is large, which is not conducive to the narrow frame design of the touch display device

Embodiment 1

[0050] Such as Figure 4 As shown, the first touch electrode 101 in the touch substrate 10 has an integrated structure, and the second touch electrode 102 includes a row of touch sub-electrodes 1020 and bridge point patterns 1022 connecting adjacent touch sub-electrodes 1020. The sub-electrodes 1020 are disposed on the same layer as the first touch electrodes 101 , and the bridge point patterns 1022 are disposed on different layers from the first touch electrodes 101 .

[0051] The specific arrangement of the second signal line 12 will be described below.

[0052] For example, the second signal line 12 can be arranged on the same layer as the bridge point pattern 1022, and the bridge point pattern 1022 and the second signal line 12 are made of metal material. The second signal line 12 can simplify the manufacturing process and reduce the manufacturing cost.

[0053] For another example, the second signal line 12 and the bridge point pattern 1022 can be arranged on the same l...

Embodiment 2

[0064] Such as figure 2 As shown in or 3, the first touch electrode 101 and the second touch electrode 102 are all integral structures.

[0065] In this case, the first signal line 11 and the first touch electrode 101 are arranged on the same layer, that is, both the first signal line 11 and the first touch electrode 101 are made of transparent conductive material, and the second signal line 12 and the second touch electrode The electrodes 102 are arranged in different layers, and the second signal line 12 is made of metal material. Alternatively, the second signal line 12 and the second touch electrode 101 are arranged on the same layer, that is, both the second signal line 12 and the second touch electrode 101 are made of transparent conductive material, and the first signal line 11 is different from the first touch electrode 101. Layers are provided, and the first signal line 11 is made of metal material.

[0066] By making the signal line arranged on the same layer as t...

Abstract

The embodiment of the invention provides a touch substrate and a manufacturing method thereof and a touch device, and relates to the technical field of touch. Signal lines which are connected with touch electrodes which are transversely and longitudinally arranged in a crossed manner are arranged on different layers, so that the width of a routing region can be reduced. The touch substrate comprises a plurality of transversely and longitudinally crossed first touch electrodes and second touch electrodes arranged on a substrate in a touch area, a plurality of first binding patterns and a plurality of second binding patterns arranged at one side of the touch area, first signal lines connected with the first touch electrodes and the first binding patterns, and second signal lines connected with the second touch electrodes and the second binding patterns; the first signal lines and the second signal lines are arranged on different layers; and the projection of the area in which the first signal lines are located on the substrate and the projection of the area in which the second signals are located on the substrate have one part of overlapping area.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a touch substrate, a manufacturing method thereof, and a touch device. Background technique [0002] The touch screen (Touch Panel) realizes simple and flexible human-computer interaction through the calculation of the coordinates of the touch points in the touch area and information processing. With the development of electronic products, people's requirements on the visual effects of touch display devices are constantly increasing, and the narrow frame design is more and more respected by people. [0003] However, if figure 1 As shown, the touch screen in the prior art includes touch electrodes arranged horizontally and vertically, the horizontal touch electrodes 01 and the vertical touch electrodes 02 are connected to signal lines in the edge area, and all the signal lines 03 are located at the same layer, and formed by one manufacturing process. Due to the limitation...
