Abstract

The invention provides a method for processing touch screen conductive glass with double-side shadow elimination. The method comprises the following steps of step 1, processing an upper glass substrate and a lower glass substrate; step 2, sputtering a first upper transparent layer, an upper transparent passivation layer, a second upper transparent layer, a lower interference layer and a lower transparent passivation layer on the upper glass substrate and the lower glass substrate; and step 3, on the basis of the second step of sputtering, sputtering an upper interference layer, a lower transparent layer and an ITO film on the upper glass substrate and the lower glass substrate. The method for processing the touch screen conductive glass with the double-side shadow elimination provided by the invention has good effects in electromagnetic shielding, electrostatic protection and eliminating the shadow, can completely replace the existing traditional conductive glass, and provide the conductive glass used for producing a capacitive screen with low energy consumption, high uniformity and low cost for downstream 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 double-sided shadow-eliminating 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 ...
