Abstract

The invention discloses a backlight module and a display device. The backlight module comprises a back plate, a reflector plate and a light guide plate which are arranged in sequence; a light bar which is arranged on the first side of the light guide plate; and multiple positioning assemblies which are arranged at the two ends of the first side of the light guide plate respectively, wherein each positioning assembly comprises a positioning piece and a guide face, the positioning assemblies are arranged on the back plate, and the guide faces are arranged at the corners of the first side of thelight guide plate. According to the technical scheme provided by the embodiment of the invention, the positioning assemblies are arranged on the first side of the light guide plate where the light baris located, so that the light guide plate is driven to move in the direction deviating from the supporting piece under the counter-acting force of the positioning assemblies when expanding, and the problem of melting of the light guide plate near the light bar can be solved.

Description

technical field [0001] The present disclosure generally relates to the field of display technology (eg, the field of computer technology), and in particular, to a backlight module and a display device. Background technique [0002] In the side-type backlight module, the optical components of the backlight are composed of a light bar, a reflector, a light guide plate and an optical film. The light bar is the heat source, and the distance between the light guide plate and the LED surface of the light bar is generally 0.3-0.5mm. The temperature of the LED surface is very high. When the LED drives a large current, the light energy radiated from the LED surface is enhanced, which can melt the light guide plate. Especially in an environment with a temperature above 40°, the temperature of the light guide plate near the light bar will increase greatly, causing the light guide plate to melt and deform, seriously affecting the quality of the backlight.
