Problems solved by technology

However, the light-gathering performance of the light guide plate of the backlight module in the related art is poor, so that the light intensity transmitted to the optical film through the light guide plate is relatively weak, which reduces the light output effect of the backlight module.
At the same time, the side of the light guide plate of the backlight module in the related art is also easy to leak part of the light, and the leaked part of the light will form a light package after being diffused and emitted by the backlight module, and the formation of the light package will not only reduce the use efficiency of light, It will also cause the backlight module to be unable to effectively control the light angle

Abstract

The invention discloses a backlight module and a display device. The backlight module comprises a light guide plate, a light source and an optical film; the light guide plate is provided with a lightemitting surface, a bottom surface and a light incident surface, the light emitting surface and the bottom surface are oppositely arranged, the light incident surface is connected with the light emitting surface and the bottom surface, the bottom surface is provided with a microstructure, and the microstructure includes at least two light guide blocks formed by extending outwards from the bottom surface; the light source and the light incident surface are oppositely arranged; and the optical film and the light emitting surface are oppositely arranged. According to the technical scheme, the light emitting effect of the backlight module can be improved, meanwhile, the use efficiency of light is guaranteed, and the light emitting angle can be effectively controlled.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to a backlight module and a display device using the backlight module. Background technique [0002] The backlight module generally includes a light source, a light guide plate, and an optical film. The light emitted by the light source is guided to the optical film through the light guide plate. However, the light-gathering performance of the light guide plate of the backlight module in the related art is poor, so that the intensity of the light transmitted to the optical film through the light guide plate is relatively weak, which reduces the light output effect of the backlight module. At the same time, the side of the light guide plate of the backlight module in the related art is also easy to leak part of the light, and the leaked part of the light will form a light package after being diffused and emitted by the backlight module, and the formation of the light package ...
