Abstract

The invention provides a backlight module, comprising a light guide plate and a support and also comprising a display device, comprising the above backlight module and a display module arranged in theoutgoing light direction of the backlight module. The backlight module has the advantages that on one hand, the light guide plate and the support which are integrated can be disassembled directly, sothat poor display effect of the light guide plate due to the support scratching the light guide plate during the removal of the light guide plate from the support is avoided; on the other hand, lightfrom the a light source enters a first concave face of an incoming light portion, part of the light is reflected by a first plane, the first concave face provides further reflection for the light reflected by the first plane which is reflected to a light guide portion, and the other part directly enters the first concave face via a first convex face and is reflected to the light guide portion viathe first concave face; a light propagation path is effectively split via the first convex face, the first plane and the first concave face in conjunction with scattering of mesh points, and therefore, the light can emerge evenly via the outgoing light face.

Description

technical field [0001] The invention belongs to the field of display technology, and more specifically relates to a backlight module and a display device. Background technique [0002] The backlight module is one of the key components of the liquid crystal display device, which is mainly used to provide sufficient brightness and uniformly distributed light source so that the liquid crystal panel can display images normally. A backlight module for a non-ultra-thin display usually includes a light guide plate, a bracket connected to the light guide plate, and a light source. For example, an LED backlight module usually includes an LED light source, a light guide plate, a reflective film and a diffusion film arranged on the surface of the light guide plate, and a backlight module bracket. When disassembling the LED backlight module, it is necessary to sequentially assemble or disassemble the above-mentioned components, the process is very complicated, and the disassembly proce...
