Problems solved by technology

In addition, the touch circuit is directly integrated on the transparent cover, which has the advantages of low cost, high penetration rate and thinner thickness, but relatively, due to poor structural protection, it cannot provide better electrostatic protection.
The current ESD protection mechanism uses extra wires to release the instantaneous high current, but because it cannot completely cover the entire touch panel, the ESD protection ability is reduced, and the additional film will affect the light transmittance and other problems.

Abstract

The invention discloses a touch panel having an electrostatic protection structure, which includes a transparent substrate, multiple sensing electrodes, a decoration layer and the electrostatic protection structure. The transparent substrate has an active region and a decoration region surrounding the active region. The sensing electrodes are formed on the active region. The decoration layer is disposed on the decoration region. The electrostatic structure includes a conductive ring. The conductive ring is disposed in surrounding arrangement corresponding to the decoration region and is located between the decoration layer and the transparent substrate.

Description

technical field [0001] The present invention relates to a touch panel, and in particular to a touch panel with an electrostatic protection structure. Background technique [0002] Since the development of touch panel technology, touch panels have occupied a very high market share in consumer electronic products. Currently, there are touch display panels integrated with touch and display functions in the market, which can be used in portable consumer electronic products, such as wireless communication mobile phones, notebook computers, tablet computers, digital cameras and other products. [0003] Most of the electronic products integrated with the touch function on the market directly assemble the touch panel and the display panel, and then transmit the touch signal and the display signal through respective signal lines. In addition, the touch circuit is directly integrated on the transparent cover, which has the advantages of low cost, high penetration rate and thinner thi...
