Abstract

The invention provides a touch substrate, a manufacture method thereof, and a touch screen, and belongs to the technical field of touch. The touch substrate comprises a touch area and a black matrix graph which surrounds the touch area; the touch substrate is provided with a plurality of touch electrodes, wherein a virtual electrode graph is formed in each gap between the adjacent touch electrodes; and each virtual electrode graph overlapped between the touch electrodes on the black matrix graph consists of a plurality of mutually-insulated virtual electrode blocks.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a touch substrate, a manufacturing method thereof, and a touch screen. Background technique [0002] In recent years, with the improvement of the controllability of mobile electronic devices and the development of electronic technology, touch screen technology has been widely used in electronic devices such as mobile phones, tablets, and notebook computers. In the development of touch technology, different technical directions such as resistance, capacitance, and electromagnetic have emerged. Capacitive touch screens have become mainstream products due to their low cost and excellent user experience. [0003] With the rapid growth of capacitive touch screens, people have higher and higher requirements for ESD (Electro-Static Discharge, electrostatic discharge) performance of touch products. Electrostatic discharge may cause the performance of the internal components of the touch ...

Problems solved by technology

Black matrix graphics are generally made of carbon balls. Usually, black matrix graphics have better insulation performance, but after multiple high-temperature processes, the resistivity of black matrix graphics decreases and the insulation performance decreases. In this way, when the static charge of equipment or human body comes into contact When the electrode blocks on the black matrix pattern are used, a huge discharge current is formed instantly between different electrode blocks, resulting in the breakdown of the black matrix pattern, resulting in an open circuit or short circuit between the electrode blocks, resulting in poor or permanent touch performance in the corresponding area. After a large amount of data verification, it is found that the breakdown between different electrode blocks generally occurs between the touch electrode and the adjacent dummy electrode
