A kind of processing method of double-sided coated glass for capacitive screen and double-sided coated glass

Abstract

The invention relates to the technical field of conductive glass, and discloses a method for machining a piece of double-sided coated glass for a capacitive screen and the double-sided coated glass. The double-sided coated glass is characterized in that a transparent conductive film I is arranged on a transparent passivation layer on a tin surface of a glass substrate; and a transparent conductive film II is arranged on a disapparation layer on an air surface. The machining method comprises the following steps of: firstly processing an original glass substrate, sputtering the disapparation layer (6) and the transparent passivation layer (4) onto the glass substrate, and then sputtering an indium tin oxide conductive film respectively on the transparent dissapparation layer and the transparent passivation layer of the glass substrate. Due to the adoption of the method, an indium tin oxide conductive film etching circuit can be prevented from being etched by an acid solution in a production process, and a good electromagnetic shielding, electrostatic protection or disapparation effect can be realized. The double-sided coated glass can completely substitute traditional conductive glass, the double-sided coated glass for the capacitive screen, which is low in energy consumption, high in uniformity and low in cost, can be provided for downstream customers.

Description

technical field [0001] The invention relates to the technical field of conductive glass, in particular to a method for processing double-sided coated glass for capacitive screens and the double-sided coated glass. 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 existi...
