Abstract

The backlight module comprises a back plate, at least two lamp plates, a diffusion plate and multiple layers of optical films which are arranged in a stacked mode, the at least two lamp plates are arranged on one side of the back plate, the diffusion plate is arranged on the sides, away from the back plate, of the lamp plates, and the multiple layers of optical films are arranged on the sides, away from the lamp plates, of the diffusion plate. The backlight module further comprises at least two magnetic attraction parts, the at least two magnetic attraction parts are arranged on the back side of the lamp panel, and the at least two magnetic attraction parts attract the lamp panel installation side of the back panel. In this way, each lamp panel is fixed to the back plate through the corresponding magnetic attraction part, and on one hand, each lamp panel is detachably arranged; and on the other hand, when the lamp panels are heated to expand, the different lamp panels fixed to the back plate in a magnetic attraction mode can move, and then the lamp panels are prevented from being extruded and deformed.

Description

technical field [0001] The present application relates to the field of display technology, and particularly designs a backlight module and a display device. Background technique [0002] Compared with traditional LED (Light Emitting Diode, light-emitting diode) backlight LCD (Liquid Crystal Display, liquid crystal display) display technology, LCD display technology using Mini LED backlight technology has better performance in dynamic contrast ratio, brightness, color gamut, and viewing angle. It has the advantages of thin and light, high image quality, low power consumption and energy saving. [0003] Limited by the existing manufacturing process of Mini LED light boards, generally only small-sized Mini LED light boards can be produced. When making large-sized Mini LED TVs, multiple Mini LED light boards need to be spliced ​​together. At present, the LED lamp panel is usually directly fixed to the back panel by means of gluing or the like, and such a fixing method makes the...
