Embodiment 1

[0031] An embodiment of the present invention provides an OGS touch screen, including a light-transmitting area and a frame area surrounding the light-transmitting area, a touch function layer is provided on the base substrate of the light-transmitting area, and a white light-shielding layer is provided on the base substrate of the frame area. Fluorescent agent is doped in the white light-shielding layer, and the fluorescent agent can absorb ultraviolet light and emit blue light.

[0032] It should be noted that ultraviolet light refers to the invisible short-wave light in the ambient light source. The white OGS touch screen is used in a normal environment, and the light emitted by sunlight and ordinary fluorescent lamps has invisible short-wave light. The fluorescent agent will realize the transition of electronic energy by absorbing invisible short-wave light, and when the energy is released again, it will emit relatively long visible light, which is mainly distributed in the...

Embodiment 2

[0039] An embodiment of the present invention provides an OGS touch screen, including the OGS touch screen provided in the above embodiment.

[0040] The beneficial effects of the embodiments of the present invention are as follows: by adding a fluorescent agent to the white light-shielding layer to adjust the chromaticity of the white light-shielding layer, the fluorescent agent can absorb invisible ultraviolet light and emit blue visible light, which is different from the original reflection of the white light-shielding layer The yellow light complements each other to form white light, so as to improve the phenomenon that the white frame of the OGS touch display screen is visually yellowish, and improve the product yield.

Embodiment 3

[0042] see figure 2 , an embodiment of the present invention provides a method for preparing an OGS touch screen, including:

[0043] 201. Form a white light-shielding layer in a frame region of a base substrate, where the white light-shielding layer is doped with a phosphor, and the phosphor is capable of absorbing ultraviolet light and emitting blue light.

[0044]201. Form a touch function layer in a light-transmitting region of a base substrate.

[0045] The beneficial effects of the embodiments of the present invention are as follows: by adding a fluorescent agent to the white light-shielding layer to adjust the chromaticity of the white light-shielding layer, the fluorescent agent can absorb invisible ultraviolet light and emit blue visible light, which is different from the original reflection of the white light-shielding layer The yellow light complements each other to form white light, so as to improve the phenomenon that the white frame of the OGS touch display scr...

Abstract

The invention discloses an OGS (One glass solution) touch screen and a preparation method thereof, and an OGS touch display screen, and aims at solving the problems that a white frame of the OGS touch screen prepared by the prior art is yellowed due to high-temperature preparation at a plurality of times, the white frame of the touch display screen employing the OGS touch screen is visually close to yellow, and poor product is caused. The OGS touch screen comprises a light transmission area, and a frame area surrounding the light transmission area; a touch functional layer is arranged on a substrate base plate of the light transmission area; a white shading layer is arranged on the substrate base plate of the frame area; a fluorescent agent is doped in the white shading layer to absorb ultraviolet light and emit blue light.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to an OGS touch screen, a preparation method thereof, and an OGS touch screen. Background technique [0002] The white One G1ass Solution (OGS) touch screen forms a white light-shielding layer on the frame area of ​​the OGS touch screen through photolithography of white photoresist or silk screen white ink to achieve white visual effect. In the manufacturing process of the existing OGS touch screen, multiple high-temperature processes are required, such as ITO coating and photolithography organic photolithography material (Over Coat, OC) and other processes. The white light-shielding layer of the white OGS touch screen will cause yellowing of the white photoresist or the organic resin in the ink after multiple high-temperature processes, that is, the white light-shielding layer of the white OGS touch screen frame area will yellow. After the white OGS touch screen is applied t...
