Abstract

The invention provides a touch panel preparation method, a touch panel and a touch device. The touch panel comprises a first metal layer, an insulating layer and a second metal layer, wherein the first metal layer is arranged on a substrate; the first metal layer comprises a first touch electrode area, a signal wiring area and a redundant wiring area; the insulating layer is arranged on the firstmetal layer; the second metal layer is arranged on the insulating layer; the second metal layer comprises a second touch electrode area; positive projection, on the substrate, of the second touch electrode area is overlapped with positive projection, on the substrate, of a touch dead zone formed by the signal wiring area and the redundant wiring area of the first metal; and through the setting ofthe second touch electrode area, the touch dead zone of the first metal layer forms a conductive channel, so as to realize a touch function.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a method for preparing a touch panel, a touch panel and a touch device. Background technique [0002] Since the rise of touch technology, its popularity has been increasing. According to different sensing methods, touch screens can be roughly divided into external touch screens and built-in touch screens. Plug-in touch screens can be mainly divided into G+G, GFF, OGS, and On cell, among which On cell touch screen refers to the method of embedding the touch screen between the color filter substrate and polarizer of the display screen, that is, on the LCD panel. Configure the touch sensor. The in-cell touch screen integrates the touch device between the color filter substrate and the array substrate, so it is called an In cell touch screen. Both On cell and In cell are developing toward large size. In order to accommodate larger screens with limited body size, increase scr...
