Embodiment

[0039] Such as figure 1 as shown, figure 1 is the schematic diagram of the cover plate in the embodiment. In this embodiment, the cover plate 10 of the present invention includes a first substrate 110 , a second substrate 120 and a light shielding structure 130 .

[0040] Such as figure 2 as shown, figure 2 is the schematic diagram of the first substrate in the embodiment. The thickness of the first substrate 110 is 30-60 microns. The first substrate 110 includes a first substrate 111 and a first flexible layer 112, wherein the first substrate 111 is a hard transparent glass substrate, and the material of the first substrate 111 includes at least one of silicon oxide, boron oxide and aluminum oxide, The first substrate 111 has high external quality and internal strength, and its surface is smooth, which can completely transmit light.

[0041] The first flexible layer 112 is arranged on the first substrate 111, and its material is polyimide resin or modified polyimide r...

Abstract

The application discloses a cover plate and a preparation method thereof and a display device. The cover plate comprises a first substrate, a second substrate arranged opposite to the first substrate,and a shading structure arranged between the first substrate and the second substrate. According to the embodiment of the application, the cover plate has the beneficial effects that the shading structure is arranged between the two layers of substrates; so that the technical problem that the shading structure is thinned due to friction or folding is effectively solved and the light leakage phenomenon of the display device is avoided; the shading structure is prepared through a yellow light manufacturing procedure or silk-screen printing; the preparation method is simple, mass production is facilitated, and the manufacturing cost is saved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a cover plate, a preparation method thereof, and a display device. Background technique [0002] In a modern society, display screens are widely used in various fields such as home appliances, mobile devices, and automobiles, and have gradually become an important part of industrial equipment. Modern electronic equipment usually requires that the color of the display screen be as consistent as possible with the non-display area when it is turned off, that is, the requirement of integral black of the screen. [0003] In order to achieve this purpose, in the prior art, a black ink layer is usually printed on the non-display area around the display screen, and the structural parts are blocked by the black ink layer, and then fully transparent glass is pasted on the black ink layer In this way, when the display screen is illuminated, the black ink layer is not conspicuous...
