preparation example Construction

[0052] figure 1 The preparation process of the shown touch substrate may include:

[0053] Toughened glass is selected as the cover substrate, and ultrasonic cleaning is performed on the cover substrate 11 . A light-shielding layer 12 located in the frame area is formed on one side of the cover substrate 11 , and yellow light coating and developing processes can be used in the process of making the light-shielding layer. A protective layer 13 is formed on the side of the light-shielding layer 12 away from the cover substrate 11. The material of the protective layer 13 is an organic substance, such as a photolithographic insulating protective glue (also called a photolithographic OC glue). In the process of forming the protective layer 13, Yellow light coating and development processes can be used, and high temperature baking at 200°C for about 30 minutes is required for curing. The first metal layer 14 is formed on the side of the protective layer 13 away from the cover subs...

Abstract

The embodiment of the invention provides a touch substrate, a preparation method thereof and a display device. The touch substrate comprises a visible region, and the touch substrate comprises a cover plate substrate; the touch structure layer is located on one side of the cover plate substrate; and the chromaticity function layer is at least located in the visible region and is configured to reduce the yellow chromaticity of the visible region of the touch substrate. The chromaticity function layer can reduce the yellow chromaticity of the visible region of the touch substrate, and the situation that the chromaticity of the visible region of the touch substrate is slightly yellow is avoided.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a touch substrate, a manufacturing method thereof, and a display device. Background technique [0002] In the field of touch control, capacitive touch screen structures include GG (Glass+Glass) structure and OGM (OGS metalmesh) structure. The GG structure uses a cover glass laminated with a touch glass. The touch screen with GG structure has double-layer glass, which is thick and heavy overall, and the experience is poor. The touch screen with OGM structure makes the touch film layer on the cover glass, realizing the integration of touch control on the cover. Compared with the touch screen with GG structure, the touch screen with OGM structure lacks a layer of glass and has a good experience effect. AIO), vehicles, etc. tend to use the structure. [0003] The touch screen with OGM structure in the prior art presents an obvious yellowish problem in the visible area ...
