Abstract

The invention provides a backlight module, a display module and a display device. The problem that in the prior art, due to the fact that a light incident surface of a light guide plate is coarse, light leakage appears in the light incident side is solved. The backlight module comprises a light guide plate and a light source located on the light incident side of the light guide plate. One side, facing a display substrate matched with the light guide plate, of the light guide plate is a light emergence surface of the light guide plate, and one side, opposite to the light source, of the light guide plate is a light incident surface of the light guide plate; and one end, close to a light emergence surface, of the light source inclines towards the light guide plate, and a first included angle formed between the light emergency direction of the light emitting center of the light source and a plane parallel to the light emergency surface is an acute angle.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a backlight module, a display module and a display device. Background technique [0002] With the rapid development of flat-panel liquid crystal display technology, more and more liquid crystal display products adopt narrow frame design to meet the needs of its simple appearance design. For this reason, compared with general module optical design schemes, narrow bezel products often adopt the following targeted methods: 1. Reduce the distance between light sources and reduce the dark area between light sources; 2. Use wide viewing angles The luminous light source expands the light-emitting area of ​​the light source; 3. The light incident surface of the light guide plate adopts prisms or other fine structures to diffuse the light incident into the light guide plate; 4. The light output surface of the light guide plate adopts prisms or other fine structures, so that...
