Abstract

The invention discloses a cold processing technology of a touch screen, which comprises the following steps of: a, selecting organic glass, and cleaning and drying the inner surface and the outer surface of the organic glass; b, coating the outer surface of the organic glass with a conductive shielding layer, and coating the inner surface of the organic glass with a conductive pattern layer; the method comprises the following steps: firstly, forming a layer of ITO film on the inner surface of organic glass in a sputtering manner, uniformly coating a layer of photoresist on the ITO film, irradiating a photomask by using UV light, and forming patterned photoresist through exposure and development steps; c, etching the ITO thin film which is not covered by the photoresist by using a wet etching method, and removing the patterned photoresist by using demolding liquid; and d, irradiating the obtained demolding liquid and photoresist in a wave band of a preset wavelength to obtain a brightness value L, setting a preset brightness value range L0-L00 according to a preset circuit pattern shape, and judging whether the obtained brightness value L is within the preset brightness value rangeor not.

Description

Technical field [0001] The present invention relates to the technical field of processing touch screens, in particular to a cold processing technology of touch screens. Background technique [0002] Common touch screens are ITO conductive film touch screens. Generally, after etching the ITO conductive pattern on the ITO conductive film, the conductive silver paste circuit is screen printed around the ITO conductive pattern, and the conductive silver paste circuit is connected with the ITO conductive pattern. The ITO conductive pattern is connected to the screen driver chip through a conductive silver paste circuit to realize the touch function. In the existing ITO conductive film touch screen processing technology, the ITO pattern and the peripheral driving silver paste line are processed separately, and the processing steps are relatively complicated and the production efficiency is low. [0003] The capacitive touch screen technology uses the current induction of the human body ...
