Abstract

A touch electrode array and a touch display device are disclosed. The touch electrode array is disposed on a substrate and includes at least one first sensing electrode and at least one guard electrode. The first sensing electrode is made of a mesh structure. The mesh structure includes a solid portion and at least one open portion defined by the solid portion. The at least one guard electrode overlaps the at least one open portion in one direction. additionally the touch display device comprising the touch electrode array is put forward.

Description

technical field [0001] The present invention relates to an electrode array and an electronic device including the electrode array, and in particular to a touch electrode array and a touch display device. Background technique [0002] In recent years, a touch panel has become one of the popular electronic devices in daily life. Electronic devices usually include many signal wires to transmit signals. However, these signal wires may become discharge paths for electrostatic discharge, especially the thinner signal wires are more likely to be damaged by the large current generated during electrostatic discharge, resulting in damage to the signal wires. Taking the touch panel as an example, the areas that are most likely to be damaged by static electricity concentrate on the bridges of the sensing electrodes. The bridge portion damaged by static electricity reduces the yield and reliability of the touch panel. In view of this, how to design a touch panel with an electrostatic ...
