Problems solved by technology

Although this preparation method can obtain the color touch screen panel with the above structure, it still has the following problems: due to the need to use hydrofluoride in the preparation process, and the warming potential of hydrofluoride is 23000 times that of carbon dioxide, its impact on climate change It has a very large impact, so hydrofluoride is very polluting to the environment and must be strictly controlled, and hydrofluoride can corrode the glass substrate, once the glass substrate is damaged, the product will be scrapped, so the scrap rate of this preparation method relatively high

Abstract

The invention discloses a method for manufacturing panels of color touch screens. The method includes steps of providing substrates; coating positive photoresist layers on the substrates; exposing, developing and solidifying the positive photoresist layers, removing exposed portions of the positive photoresist layers by means of developing and reserving unexposed portions of the positive photoresist layers; forming optical film layers on the reserved portions of the positive photoresist layers and certain regions on the substrates; removing films on the reserved portions of the positive photoresist layers so as to remove first certain portions of the optical film layers, and reserving second certain portions of the optical film layers; forming nontransparent insulating layers on the reserved portions of the optical film layers. The certain regions on the substrates correspond to the portions, which are removed by means of developing, of the positive photoresist layers. The first certain portions of the optical film layers cover the reserved portions of the positive photoresist layers. The second certain portions of the optical film layers cover the regions, which correspond to the certain portions of the positive photoresist layers, of the substrates, and the certain portions of the positive photoresist layers are removed by means of developing. The method has the advantages that problems of environmental pollution and corrosion on substrates made of glass materials due to hydrofluoride can be solved, accordingly, the yield can be increased, manufacturing procedures are easy to control, and the method is suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a method for preparing a color touch screen panel. Background technique [0002] The touch screen manufacturing technology is becoming more and more mature. The OGS (one glass solution) method of making the touch unit on the touch screen cover is the mainstream way to realize the ultra-thin touch screen. With the development of touch screen technology, the appearance is colorful and personalized. into a development trend. [0003] An existing color touch screen panel includes a substrate, an optical film layer covering the substrate, and an opaque insulating layer covering the optical film layer. The patterns of the optical film layer and the opaque insulating layer are the same and corresponding. When light passes through the When the substrate irradiates the optical film, a part of the light will be reflected by the contact interface between the optical film and the subs...
