Abstract

The present invention discloses a light guide plate. The light guide plate comprises an in-light surface, an out-light surface, a reflective surface and a first reflective surface; the out-light surface and the reflective surface are oppositely arranged; the first reflective surface is connected between the out-light surface and the in-light surface; the in-light surface is connected between the first reflective surface and the reflective surface, and the in-light surface is configured to receive the ray of light of the light source, and the first corner cut is an acute angle. The present invention further discloses a backlight module and a display device. The structure of the light guide plate is helpful for improving the display effect of the display device.

Description

technical field [0001] The invention relates to the technical field of backlight sources for liquid crystal displays, in particular to a light guide plate and a backlight module. Background technique [0002] The backlight module in the prior art is usually a side-type backlight structure, that is, the light source is located on the side of the light guide plate, that is to say, the side of the light guide plate is the light incident surface, and the top surface of the light guide plate is the light output surface. A reflective sheet is added to the bottom surface of the light panel to reflect more light to the light-emitting surface. However, in the backlight module in the prior art, since the light guide plate is a cuboid board-mounted structure, the sides of the light guide plate are usually perpendicular to the top surface and the bottom surface. The reason for the bright line is that it is close to the light source and the light is concentrated in one area after reflec...
