Preparation method of capacitive touch screen electro-conductive glass with shadow eliminating function

Abstract

A method for preparing conductive glass for a capacitive touch screen with a shadow-eliminating function, the steps of which are: selection of electronic grade glass, glass substrate cutting, glass automatic edging, cleaning, edging inspection, cleaning, inspection, and loading on a host , Heating, using a magnetron sputtering coater to coat a silicon dioxide barrier film, using a magnetron sputtering coater to coat an indium tin oxide film, using a magnetron sputtering coater to coat a tantalum pentoxide film and a silicon carbide disappearing film, Cooling, host unloading, performance test of indium tin oxide film. The prepared conductive glass has low square resistance, good uniformity of surface resistance, high light transmittance and short etching time, glass double-sided coating, multi-layer film continuous coating, conductive glass has shadow elimination function, and improves production High efficiency and low cost, the prepared conductive glass can be widely used in high-end smart capacitive touch screens.
