Abstract

The invention provides a machining method of double-face touch screen shadow eliminating conducting glass. The machining method includes the steps that firstly, an upper glass substrate and a lower glass substrate are treated; secondly, a first upper interference layer, an upper transparent passivation layer, a first lower interference layer and a lower transparent passivation layer are sputtered on the upper glass substrate and the lower glass substrate; thirdly, a second upper interference layer and a second lower interference layer are sputtered on the upper transparent passivation layer and the lower transparent passivation layer sputtered on the upper glass substrate and the lower glass substrate. The good electromagnetic shielding, electrostatic protection and shadow elimination effects are achieved, existing traditional conducting glass can be completely replaced, and the conducting glass which is low in energy consumption, high in uniformity and low in cost and is used for manufacturing a capacitance screen is 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 the shadow-eliminating conductive glass for a double-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 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 o...
