Light guide plate, backlight module and display device

Abstract

The invention provides a light guide plate, a backlight module and a display device, and relates to the technical field of display. The light guide plate comprises a light guide plate body and a photoluminescence layer. The light guide plate body and the photoluminescence layer are arranged in a stacked manner; the light guide plate body is provided with a first bottom surface and a second bottomsurface which are opposite to each other, light rays which are transmitted into the light guide plate body can be conducted between the first bottom surface and the second bottom surface, and a plurality of light emergence structures which are arranged at intervals are distributed on the first bottom surface, so that parts of the light rays can be transmitted out from the light emergence structures; the photoluminescence layer is arranged on the side where the first bottom surface of the light guide plate body is located. The light guide plate, the backlight module and the display device havethe advantages that the quality of the backlight module can be improved, and accordingly the display quality of an LCD (liquid crystal display) can be guaranteed.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light guide plate, a backlight module and a display device. Background technique [0002] With the development of display technology, LCD (Liquid Crystal Display, liquid crystal display) has become the mainstream display in the field of display technology due to its advantages of thin and light body, low power consumption, no radiation, and long service life. [0003] Since the existing LCD does not have the function of self-illumination, a backlight module needs to be used to provide a light source for the display. In the backlight module in the prior art, in order to make the brightness and uniformity of the light source entering the display panel meet the requirements, the backlight module usually needs to be equipped with a diaphragm, and the diaphragm is prone to problems such as scratches, wrinkles, and looseness. The display quality of the LCD will be affected during u...
