Abstract

A method for processing single-face touch screen shadow eliminating conductive glass comprises the following steps: 1, treating a glass baseplate; 2, sputtering an intervention layer I and a transparent passivation layer on the glass baseplate; 3, sputtering an intervention layer II on the transparent passivation layer sputtered on the glass baseplate. The single-face touch screen shadow eliminating conductive glass has excellent electromagnetic shielding, stelectrostatic protection and shadow elimination functions, and can completely replace the conventional conductive glass, and the conductive glass, with low energy consumption, high uniformity and low cost, used for manufacturing capacitive screens can be provided for downstream clients.

Description

Technical field [0001] The invention relates to the technical field of conductive glass, in particular to a method for processing shadow-free conductive glass for a single-sided 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 strict performance requirements, such as uniformity, heat resistance, acid and alkali resistance Performance, high temperature and humidity resistance, etc.; when making transparent circuits, due to increased process difficulty, acid etching circuits are often used when making circuits. During the production process, parts that should not be etched are easy to etch away, and there are etched traces of circuit etching, which affect its electromagnetic shielding and electrostatic protection functions. The existing etched traces will affect the viewing pattern...
