Protective glass of display panel, preparation method of protective glass, display panel and display device

Abstract

The invention relates to the technical field of display, and discloses protective glass of a display panel, a preparation method of the protective glass, the display panel and a display device. The protective glass of the display panel comprises a glass substrate, a white light-blocking layer, an isolating layer and a black matrix layer, wherein the white light-blocking layer is positioned on the glass substrate, and the white light-blocking layer is arranged along the frame area of the glass substrate; the isolating layer is positioned on the white light-blocking layer; the black matrix layer is positioned on the isolating layer, and the black matrix layer is arranged along the frame area of the glass substrate. In the protective glass of the display panel, the two layers of structures including the white light-blocking layer and the black matrix layer are sequentially arranged on the frame area of the glass substrate, the isolating layer is arranged between the white light-blocking layer and the black matrix layer, so that the permeation effect and the color disturbing influences caused by the black matrix layer to the white light-blocking layer can be avoided, therefore, the protective glass of the display panel can be displayed to be the white frame, in addition, the white frame is pure in color, high in color purity and small in color cast, and the user experience is good.

[0002] At present, capacitive touch screen has become a very common electronic product, and OGS (One Glass Solution) is one of the mainstream products. Due to the individual pursuit of consumers, the traditional black border OGS can no longer meet the needs of mass consumption. Some touch screen manufacturers The developed white border OGS has gradually moved from the experimental stage to the stage of small batch mass production

[0003] Due to the poor light-shielding properties of white photoresist (WBM) materials, the frames of existing white frame OGS products generally include a two-layer structure of white photoresist (WBM) layer and black matrix (BM) layer to avoid The metal wires inside are seen through; however, this kind of frame adopts the OGS product with WBM layer and BM layer structure, the white color of the frame area is often not pure enough, the color shift is serious, and the user's visual experience is poor.
