Abstract

A processing method for single-sided shadow eliminating conductive glass of a touch screen comprises following steps: step 1, a glass substrate is processed; step 2, an interference layer I, a transparent passivation layer, an interference layer II and a transparent layer are sputtered on the glass substrate; step 3, an ITO (indium tin oxide) film is sputtered on the glass substrate on the basis of sputtering in the step 2. The single-sided shadow eliminating conductive glass has good electromagnetic shielding, electrostatic protection and shadow eliminating functions and can completely replace the traditional conductive glass, and the conductive glass having low energy consumption, high uniformity and low cost and used for production of a capacitive touch screen is provided for down-stream customers.

Description

technical field [0001] The invention relates to the technical field of conductive glass, in particular to a method for processing conductive glass for a single-sided shadow-elimination touch screen. Background technique [0002] At present, capacitive screen products are widely used, and the double-sided conductive glass in the capacitive screen is its main component. The conductive film coated with conductive glass on both sides has relatively strict performance requirements, such as uniformity, heat resistance, acid and alkali resistance. Performance, high temperature and high humidity resistance, etc.; when making transparent circuits, due to the increased process difficulty, acid engraved circuits are often used when making circuits. During the production process, it is easy to etch away parts that should not be etched, and there are traces of circuit etching, which affect its electromagnetic shielding and electrostatic protection functions, and the existing traces of et...
