Problems solved by technology

In addition, the touch circuit is directly integrated on the substrate, 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.

[0040] Please refer to figure 1 and figure 2 , which respectively show a schematic top view and an enlarged schematic view of a partial area of ​​the touch panel 100 with electrostatic protection according to an embodiment of the present invention. The touch panel 100 includes a substrate 110 , a plurality of sensing electrodes 120 , a plurality of wires 130 and an ESD protection wire 140 . The substrate 110 has a touch sensing area 112 and at least one surrounding area 114 . Wherein, the surrounding area 114 can continuously surround the touch sensing area 112 (such as figure 1 and figure 2 shown), or only be disposed on at least one frame side of the substrate 110 (not shown). The touch screen is correspondingly displayed in the touch sensing area 112 for the user to operate in the touch sensing area 112 by means of touching, dragging or clicking. The sensing electrodes 120 are formed on the touch sensing area 112 to generate touch signals in response to user operatio...

Abstract

Touch panel having electrostatic protection is provided. The touch panel includes a substrate, a plurality of sensing electrodes, a plurality of conductive wires and an electrostatic protection line. The substrate has a touch sensitive area and a periphery area surrounding the touch sensitive area. The inner part of the periphery area is a first layout area. The outer part of the periphery area is a second layout area. The sensing electrodes are formed in the touch sensitive area. The conductive wires are disposed in the first layout area. The electrostatic protection line is disposed in the second layout area and adjacent to the conductive wires. The width of the electrostatic protection line is greater than that of the conductive wires. The distance separating the outside of the electrostatic protection line from the border of the substrate is smaller than 48.12 mm and greater than or equal to 0.3 mm.

Description

technical field [0001] The invention relates to a touch panel, and in particular to a touch panel with electrostatic protection. 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 substrate, which has the advantages of low cost, high penetration rate, and thinner thickness. However, relatively,...
