Problems solved by technology

[0002] At present, the conductive polarity of the touch panel needs to use the indium tin oxide compound as the conductive layer, and it is made on the insulating substrate through the process of vacuum coating and etching. Metal indium is a scarce resource, and the price in the market has been relatively high recently, resulting in an increase in the cost of raw materials

Abstract

The present invention relates to an electrode structure of a touch panel, in particular to a capacitive touch electrode structure. The capacitive touch electrode structure comprises a substrate and metal conductive grid layers. The substrate is a single-layer film substrate. The metal conductive grid layer is arranged on both sides of the single-layer film substrate; one metal conductive grid layer is a driving layer and the other metal conductive grid layer is a sensing layer; the sensing layer metal grid has a plurality of sensing electrodes, and the sensing electrode comprises a plurality of sensing lines; the driving layer metal grid comprises a plurality of driving electrodes, and the driving electrode has a plurality of driving lines; the driving electrodes and the sensing electrodesare composed of a plurality of grids, and the driving lines and the sensing lines between the driving electrode and the sensing electrode are independent of each other through disconnection between the grids. According to the technical scheme of the present invention, mutual capacitance is formed by independent driving and independent sensing through a single-sided double layer, and break of theelectrode is shielded by using the linear barrier, so that the capacitive touch electrode structure can achieve the advantages of a thinner structure, better drawing effects, excellent stability and asimple process.

Description

technical field [0001] The invention relates to an electrode structure of a touch panel, in particular to an electrode structure of a capacitive touch. Background technique [0002] At present, the conductive polarity of the touch panel needs to use the indium tin oxide compound as the conductive layer, and it is made on the insulating substrate through the process of vacuum coating and etching. Metal indium is a scarce resource. Recently, the price in the market has been relatively high, resulting in an increase in the cost of raw materials. The new metal mesh touch screen technology (MetalMesh) can effectively solve the problem of high cost, and this technology can also make consumer electronics develop into the thin and light market, allowing users to have a better experience. The conductive polarity of the sensing end of the existing MetalMesh touch screen uses a metal grid instead of indium tin oxide to make a touch electrode, which is a double-layer structure. The gra...
