Abstract
The invention provides a manufacturing process for an OGS touch screen. The manufacturing process comprises the following steps: preparing a base plate; coating an ITO (indium tin oxide) film layer on an upper surface of the base plate; etching a needed pattern on the ITO film layer; performing silk-printing of printing ink on the base plate and the ITO film layer, and reserving a plurality of clear areas without screen printing ink in the ITO film layer, so that any clear area and printing ink at the periphery of any clear area form filling holes; filling first conductive slurry which is in conductive connection with the ITO film layer in the filling holes, and curing the first conductive slurry; performing silk-printing of second conductive slurry which is in conductive connection with the first conductive slurry on cured first conductive slurry, and curing the second conductive slurry; covering a protective layer on an assembly body of the second conductive slurry, the first conductive slurry, printing ink, the ITO film layer and the base plate. According to the manufacturing process for the OGS touch screen disclosed by the invention, a conductive channel is formed by the ITO film layer, the first conductive slurry and the second conductive slurry, so that conductive drive work of a product is favorably guaranteed. The invention further provides an OGS touch screen.
Description
technical field [0001] The invention relates to the technical field of OGS touch screens, in particular to an OGS touch screen and a manufacturing process of the OGS touch screen. Background technique [0002] OGS has become the leading technology direction of the current touch industry. The benefits of OGS (One Glass Solution, that is, integrated touch) are three points: (1) save the cost of a layer of glass and reduce the cost of one-time lamination; (2) reduce weight; (3) increase light transmittance. OGS can better meet the needs of ultra-thin smart terminals and improve the display effect. It is an inevitable choice for high-end brand terminals since 2012. The current capacitive touch screen structure is mainly divided into two categories, plug-in type and built-in type. The plug-in type is divided into three types, Glass-Glass structure, Glass-Film structure and OGS (One Glass Solution) structure; the embedded type is divided into in cell and on cell structures. For...
