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

The invention discloses a backlight module and a display device. Wherein, the backlight module includes a light guide plate, the light guide plate has a light-emitting surface and a bottom surface arranged oppositely, and a light-incident surface connecting the light-emitting surface and the bottom surface, the bottom surface is provided with a microstructure, and the microstructure The structure is at least two light guide blocks extending outward from the bottom surface; a light source, the light source and the light incident surface are opposite to each other; and an optical film, the optical film and the light exit surface form a relative settings. The technical scheme of the present invention can improve the light output effect of the backlight module, and at the same time ensure the use efficiency of the light, and also make it possible to effectively control the light output angle.
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 ...
