Abstract

The application discloses a backlight module and a display device. The backlight module includes a backplane, a reflection sheet and a light guide plate arranged in sequence; and a light bar, the light bar is arranged on the first side of the light guide plate; a positioning component, several positioning components are respectively arranged on the first side of the light guide plate The positioning assembly includes a positioning piece and a guiding surface, the positioning piece is arranged on the back plate, and the guiding surface is arranged on the corner of the first side of the light guide plate. According to the technical solution provided by the embodiment of the present application, by arranging a positioning component on the first side of the light guide plate where the light bar is located, the light guide plate is subjected to the reaction force of the positioning member when the light guide plate expands, and the light guide plate is driven to move away from the support member. Solve the problem of melting the light guide plate near the light bar.

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.
