Problems solved by technology

[0004] Electro-Static Discharge (ESD) and its protection must be considered in the design of the touch panel. Since the Touch process does not involve semiconductor technology, it is impossible to manufacture an electrostatic protection device similar to LCD
At present, the ESD design of Touch is mainly realized by wrapping a GND line around the periphery. This method has a certain protective effect on small ESD, but it has very limited effect on large ESD, which often causes the product to lose touch. functionality, which poses challenges to product yield and performance

Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] Since the current touch panel (for example, OGS touch panel), the ESD used to discharge the static electricity generated by the touch electrode is mainly realized by wrapping a GND line around the periphery, this method is effective for the case of more static electricity Very limited, resulting in the touch panel often loses the touch function, based on this, the present invention mainly provides a solution that can prevent the touch panel...

Abstract

The invention discloses a touch panel, a touch panel manufacturing method and a display device. The touch panel manufacturing method comprises the step that a signal transmission line which is connected with a touch electrode on the touch panel and a grounding wire which intersects with the signal transmission line and is insulated from the signal transmission line are formed, wherein multiple capacitor structures used for storing static electricity are formed at the position where the signal transmission line intersects with the grounding wire. By the adoption of the touch panel, the touch panel manufacturing method and the display device, the situation that the touch function of the touch panel does not work due to poor electrostatic protection is avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a touch panel, a manufacturing method, and a display device. Background technique [0002] With the rapid development of science and technology, touch technology is widely used, for example, industrial production (central controllers, measuring instruments, etc.), life applications (smart phones, Global Positioning System (Global Positioning System, referred to as GPS) , small laptops, etc.), commercial applications (self-service cash register, point of sale (POS) for short), education and entertainment (e-books, electronic whiteboards, etc.) and medical equipment (nursing vehicles, medical diagnostic machines, etc.). [0003] At present, touch panels can be divided into resistive, capacitive, surface acoustic wave, and infrared based on the sensing principle. According to the structural relationship between the touch panel and the display screen, the touch panel can be divided ...
