Glass cover plate and preparation method thereof, display panel and display device

Abstract

The embodiment of the invention discloses a glass cover plate and a preparation method thereof, a display panel and a display device. The preparation method of the glass cover plate comprises the following steps: providing an ultra-thin glass substrate, wherein an optical film layer is formed on one side of the ultra-thin glass substrate in a roll-to-roll manner; and arranging a supporting structure on one side, deviating from the optical film layer, of the ultrathin glass substrate. According to the embodiment of the invention, the consistency of the optical performance of each position of the glass cover plate can be ensured so that the production yield of the glass cover plate can be improved; meanwhile, the display panel comprising the glass cover plate can be thinner so that the thinning of the display panel is facilitated.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to a glass cover plate and a manufacturing method thereof, a display panel and a display device. Background technique [0002] With the continuous development of display technology, displays are used more and more widely. Usually, a display is composed of a display module and a cover on the side of the display surface of the display module. The cover can protect the display module and optimize the display. Appearance. [0003] Most of the glass cover plates in the prior art are composed of a glass substrate, and in order to improve the impact resistance of the glass cover plate, an explosion-proof film is usually added to the surface of the glass substrate, that is, the glass cover plate is composed of a glass substrate and an explosion-proof film; In this way, when the glass cover plate is applied to a display, it will be unfavorable for the thinning of ...

[0003] Most of the glass cover plates in the prior art are composed of a glass substrate, and in order to improve the impact resistance of the glass cover plate, an explosion-proof film is usually added to the surface of the glass substrate, that is, the glass cover plate is composed of a glass substrate and an explosion-proof film; In this way, when the glass cover is applied to a display, it will be unfavorable for the thinning of the display, and the surface fingertips and hardness will be deteriorated

At the same time, when the glass cover is applied to a curved screen, the glass substrate of the glass cover is usually made into a curved surface, and then the corresponding functional film is formed on the surface of the glass substrate by deposition; however, since the glass substrate is The curved surface makes the angle and distance between the deposition source and each position on the surface of each glass substrate different, resulting in different thickness and properties of the functional layer deposited on the surface of the glass substrate, resulting in different optical properties of the functional film layer at each position on the glass cover plate , which reduces the production yield of the glass cover plate
