AI Technical Summary
Technical Problem
In large-size touch display panels, the use of indium tin oxide touch electrodes increases resistive-capacitive hysteresis, resulting in inaccurate touch results.
Method used
A conductive mesh structure is designed on the touch substrate to create touch electrodes and virtual electrodes. An electrostatic discharge structure is set in the peripheral area and connected to the ground wire through a conductive path to discharge the static charge in the virtual electrodes.
Benefits of technology
It effectively reduces the accumulation of static charge in the virtual electrode, lowers RC delay, and improves touch sensitivity and accuracy.

Abstract
The present disclosure provides a touch substrate having a touch electrode region and a peripheral region surrounding the touch electrode region. The touch substrate includes a touch electrode layer located at the touch electrode region and an electrostatic discharge structure located at the peripheral region. The touch electrode layer includes touch electrodes and dummy electrodes alternately arranged and spaced apart from each other along a first direction, wherein the touch electrodes and the dummy electrodes extend along a second direction crossing the first direction, the touch electrodes and the dummy electrodes are both conductive mesh structures, the dummy electrodes have a first end and a second end along the second direction and include at least one conductive path continuously between the first end and the second end. The at least one conductive path is electrically connected to the electrostatic discharge structure.
