Problems solved by technology

Therefore, when the charges continue to accumulate and form a large voltage difference, it will cause electrostatic discharge (electro-static discharge, ESD) and damage the black matrix, eventually causing in-plane light leakage or short circuit problems
[0005] Therefore, there is an urgent need to develop a touch display device that avoids the design of the surface with a small radius of curvature or sharp corners in the electrode area, so as to prevent the problem of electrostatic damage to the black matrix during the manufacturing process.

Abstract

A touch control display device comprises a display device and a touch control panel; the touch control panel is arranged on one side of the display device, wherein the touch control panel comprises a substrate, a light shield layer, and a circuit layer, the light shield layer is arranged between the substrate and the display device. The circuit layer is arranged between the light shield layer and the display device; and the circuit layer comprises a first signal electrode and a second signal electrode. The first signal electrode has a first overlapped area and a first non-overlapped area. The second signal electrode has a second overlapped area and a second non-overlapped area, wherein the first overlapped area and the second overlapped area are overlapped with the light shield layer; and the distance between the first overlapped area and the second overlapped area is greater than the distance between the first non-overlapped area and the second non-overlapped area.

Description

technical field [0001] The present invention relates to a touch display device, in particular to a touch display device capable of preventing internal static electricity from damaging a black matrix. Background technique [0002] In recent years, with the development trend of humanization and simplification of operation, touch display devices with touch panels are more and more widely used in production and life. Since the user can input signals by directly touching the touch display device with hands or other objects, thereby reducing or even eliminating the user's dependence on other input devices (such as keyboard, mouse, remote control, etc.), which greatly facilitates the user's operation. [0003] Touch panel technology can be divided into different types based on three aspects: signal generation principle, sensing technology, and screen assembly method. Depending on the principle of signal generation, it can be divided into digital and analog: digital touch signals u...
