Touch substrate, fabrication method for touch substrate, and touch apparatus

Abstract

The invention provides a touch substrate, a fabrication method for the touch substrate, and a touch apparatus. The touch substrate comprises a substrate as well as a first touch electrode graph and a second touch electrode graph that are formed on the substrate in a same-layer manner. Each second touch electrode comprises a main body part and an extension part; and the extension part of each second touch electrode is correspondingly embedded in a gap of the first touch electrode graph. The first touch electrode graph further comprises an extension part located at the end part and connected to a main body part of a first touch electrode located at the end part; a gap corresponding to the extension part of the first touch electrode graph is formed in the main body part of the second touch electrode located at the end part; and the extension part of the first touch electrode graph is embedded in the gap. According to the touch substrate provided by the invention, the end part coupling area of the second touch electrode graph and the first touch electrode graph can be enlarged, so that the sensitivity of touch detection of a region can be improved.

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] In order to reduce the thickness of the display device, a touch device is proposed in the prior art in which the emitter electrode pattern and the receive electrode pattern are made on the same layer. When the finger touches the corresponding area, the gap between the emitter electrode pattern and the receive electrode pattern A change in the capacitance of , which causes a change in the sensed current. see figure 1 , is a structural schematic diagram of a transmitter electrode pattern and a receiver electrode pattern in a touch substrate in the prior art, including a receiver electrode pattern 100 and a transmitter electrode pattern 200; wherein the receiver electrode pattern 100 includes a plurality of aligned receiving electrodes 110, which are relatively The long side...

AI Technical Summary

Problems solved by technology

figure 1 In the structure, the space defined by the receiving electrode pattern 100 in the edge area is small, so the capacitive coupling area between the receiving electrode pattern 100 and the transmitting electrode 210 in this area is also small, which is not conducive to providing touch sensitivity.
