Abstract

The invention provides a backlight module. The backlight module comprises a light bar and a supporting frame, wherein the light bar is fixed on the supporting frame, and the light bar comprises a substrate and a luminescence element which is arranged on the substrate. The backlight module also comprises a first magnetic element and a second magnetic element, wherein the first magnetic element is fixed on the supporting frame, the substrate is provided with a fixed hole corresponding to the second magnetic element, the second magnetic element is at least partially stored in the fixed hole, the second magnetic element and the first magnetic element are operated through the magnetic force so as to fix the light bar onto the supporting frame. The backlight module is simple and convenient to assemble.

Description

technical field [0001] The invention relates to a backlight module. Background technique [0002] A backlight module is generally used to provide uniform planar light for the display panel. Generally, a backlight module includes a light source, a light guide plate, an optical film, a frame, and the like. At present, a light bar (Light Bar) formed by fixing light-emitting elements such as light-emitting diodes on a circuit substrate is widely used as a light source of a backlight module. However, the above-mentioned light strip generally needs to be fixed on the frame of the backlight module by bonding, screwing, etc., and the assembly and fixing process of this light strip is complicated, which makes the assembly process of the entire backlight module cumbersome. Contents of the invention [0003] In order to solve the problem of the complicated assembly process of the backlight module in the prior art, it is necessary to provide a backlight module with a relatively simp...
