Improved manufacturing method of OGS (one glass solution) ultrathin touch screen

Abstract

The invention discloses an improved manufacturing method of an OGS (one glass solution) ultrathin touch screen. The method comprises the following steps that A, cover plate glass plated with an indium tin oxide thin film and a cover plate color is subjected to cutting, engraving and tempering, and a required cover plate glass white piece is obtained; B, acid resistance patterns are printed on the cover plate glass white piece in a silk-screen printing way, then, the etching is carried out, and the indium tin oxide thin film patterns and the visible region patterns are obtained; C, conductive silver paste is printed in a non-visible region in a silk-screen printing way, and is in lap joint with the indium tin oxide thin film through a circuit, and the OGS ultrathin touch screen is obtained. The improved manufacturing method has the advantages that the early stage equipment investment for manufacturing the OGS touch screen is reduced, the production efficiency is improved, in addition, the cost of the touch screen is reduced, and meanwhile, the characteristics of light weight and thin appearance of the OGS touch screen are also remained.

Description

technical field [0001] The invention relates to the technical field of OGS touch screen production, in particular to an improved OGS ultra-thin touch screen production method. Background technique [0002] Since the mainstream mobile phones are now taking the thinner and lighter route, touch screen products are also developing in the direction of thinner and lighter to meet the needs of the market, thus producing OGS touch screens. The traditional OGS touch screen is coated with indium tin oxide film on the cover glass by magnetron sputtering, and then coated with a layer of molybdenum aluminum molybdenum metal wiring layer, and the color of the cover glass should also be magnetron sputtered. It is sputtered by spraying, and then the required pattern is etched by yellow light. However, yellow light etching needs to use a large piece of glass for exposure, development, and etching, and the glass after cutting into small pieces needs to be strengthened twice. In addition, the...

Problems solved by technology

However, yellow light etching needs to use a large piece of glass for exposure, development, and etching, and the glass after cutting into small pieces needs to be strengthened twice. In addition, the molybdenum-aluminum-molybdenum metal wiring layer is sputtered by magnetron sputtering in the early stage. This will lead to high investment in equipment, high cost of mold opening, high cost, and it is difficult to promote it in a large area in the market.
