Abstract

The invention relates to a light guide plate and a display panel. A plurality of grooves are formed in a first surface of the light guide plate; the first surface refers to one side of the light guideplate parallel to a plane where the light guide plate is located, wherein in the direction of the light guide plate pointing to the edge from the center, the depth of a groove close to the center ofthe light guide plate is greater than the depth of the groove far away from the center of the light guide plate, thereby reducing the surface stress at the center position after the light guide plateis bent.

Description

technical field [0001] The present invention relates to the technical field of display devices, and more specifically, to a light guide plate and a display panel. Background technique [0002] With the continuous development of science and technology, more and more electronic devices with display functions are widely used in people's daily life and work, which brings great convenience to people's daily life and work, and has become an indispensable important tool missing. [0003] The shape of the display panel is different in different application scenarios. For example, in a common scenario, the display panel has a flat structure, while in some scenarios, the display panel is made into a curved structure. A light guide plate is usually used in a curved display panel. Since the light guide plate needs to be applied to a curved display panel structure, the light guide plate also needs to have a curved surface structure. In the prior art, it is usually obtained by direct pre...
