Abstract

The invention provides a metal grid touch screen and a preparation process thereof. According to the metal grid touch screen and the preparation process thereof, blackened CU alloy grid layers which contain copper oxide, copper nitride and other oxides are adopted, so that the requirement for conductivity is satisfied, and low reflectivity is realized; due to the presence of the other oxides, thereliability of film layers and the adhesive power between the film layers and substrates are improved; through adding alloyed elements in the copper, uniform mechanical property, corrosion resistanceand conductivity of Cu alloy grids can be ensured; by adoption of blackened layer and conductive layer integrated process design, the problem of high reflectivity caused by the reason that the blackened layers caused by side corrosion cannot completely cover the metal grids and the problem bad display effect can be effectively avoided; and the making process is simple, the cost is relatively low,the adhesive power between the metal grids and the substrates is good, the etching process is relatively simple, so that the production efficiency and yields of products can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a metal grid touch screen with simple manufacturing process, low cost, low reflectivity, strong adhesion and good reliability. Background technique [0002] With the gradual expansion of the application range of touch screens and the diversification of application environments, mobile terminals, wearable devices, smart home appliances and other products all have strong demand for touch panels. Diversification. Traditional ITO films have problems such as inflexibility, high resistance, sensitivity under high impedance, slow response speed, and low light transmittance. Many panel manufacturers have begun to study ITO substitutes. Among them, the development is relatively good. It is metal mesh technology. [0003] Metal grid technology utilizes silver, copper and other metal materials or oxides and other easily available and relatively cheap raw materials to press the conduc...
