Problems solved by technology

[0003] Regardless of the integrated / built-in touch panel or the external touch panel, they all face the problem of yield reduction caused by electrostatic discharge in manufacturing, and the integrated / built-in touch panel is more serious.
For example, most of the current integrated / built-in touch panels are made on one surface of the substrate first to make the touch circuit, and then make a color filter film on the other surface of the substrate. After making the color filter At the same time as the thin film, the touch circuit is often damaged by electrostatic discharge
In addition, when the user touches the integrated / built-in touch panel and the external touch panel with a finger, electrostatic discharge may also occur, which may cause damage to the touch circuit

Abstract

A touch control panel comprises a substrate, a plurality of first sensing serials and a plurality of second sensing serials, wherein the first sensing serials are configured on the substrate, each of the first sensing serials extends along the first direction and electrically insulated and comprises a plurality of sensing pads and a plurality of bridging parts each of which is electrically connected between two adjacent first sensing pads respectively; the second sensing serials are configured on the substrate, wherein each of the second sensing serials extends along the second direction and electrically insulated and comprises a plurality of sensing pads and a plurality of bridging parts each of which is electrically connected between two adjacent second sensing pads respectively, each of the second bridging parts is staggered with each of the first bridging parts, and at least one of the second bridging part is provided with at least one static discharge tip. Due to use of static discharge tip connected with the sensing serials, the inventive touch control panel has good static discharge protection.

Description

technical field [0001] The present invention relates to a touch panel, and in particular to a touch panel with good electrostatic discharge protection capability (capability of ESD protection). Background technique [0002] Touch panels are roughly classified into resistive touch panels, capacitive touch panels, optical touch panels, acoustic wave touch panels, and electromagnetic touch panels according to their sensing methods. Since the capacitive touch panel has the advantages of fast response time, good reliability and high durability, the capacitive touch panel has been widely used in electronic products. According to different structures and manufacturing methods, capacitive touch panels can be roughly divided into two types: surface-mounted and integrated / in-cell. In the surface-mounted capacitive touch panel, the sensing series is usually first fabricated on a substrate, and then the substrate with the sensing series is attached to the outer surface of the display. ...
