Problems solved by technology

At present, in order to adapt to the internal product structure of the liquid crystal display device, the light-emitting surface of the light guide plate needs to be designed with different structures, but because the light-emitting surface is uneven, the light reflected from the light-emitting surface converges in the light guide plate, thereby forming light spots in the light guide plate. Reduce the user's visual experience

Abstract

The invention discloses a backlight module. The backlight module includes a light source, a light guide plate and a light color conversion layer. The light guide plate includes a first side end surface and a second side end surface. The light source is arranged on the first side end surface. On one side, the first side end surface forms a light incident surface, the second side end surface is provided with a microstructure, and the light-color conversion layer is provided on the surface of the microstructure. The invention also discloses a display device using the above-mentioned backlight module. In the present invention, a layer of light-color conversion layer is arranged on the microstructure surface of the second side end face, so as to eliminate the light spot in the light guide plate and improve the visual experience of the user.

Description

technical field [0001] The invention relates to the technical field of electronic display, in particular to a backlight module and a display device. Background technique [0002] With the continuous improvement of consumer requirements and the continuous development of the technical level, more and more new technologies have been invented and applied to the field of liquid crystal display, aiming at improving the effect of liquid crystal display. At present, in order to adapt to the internal product structure of the liquid crystal display device, it is necessary to design different structures for the light-emitting surface of the light guide plate. However, because the light-emitting surface is not flat, the light reflected from the light-emitting surface converges in the light guide plate, thereby forming light spots in the light guide plate. Reduce the user's visual experience. [0003] Therefore, proposing a structure that can eliminate the light spot is an urgent proble...
