Abstract

The embodiment of the invention provides a backlight module which comprises a back plate, a plurality of lamp tubes, a lamp tube fixing seat and a diffusion plate, wherein the back plate is provided with a depression; the lamp tubes are arranged on the back plate; the lamp tube fixing seat is arranged on the back plate and used for fixing the lamp tubes; the lamp tube fixing seat is provided with a support part which extends towards a direction away from the back plate; a vertical projection of the support part on the back plate is positioned in the depression; and the diffusion plate is arranged above the back plate, and the support part is used for supporting the diffusion plate. By the embodiment, the force that the support part acts on the diffusion plate can be buffered and the instant impact force suffered from the diffusion plate and the damaged probability of the diffusion plate due to the impact of the support plate are reduced.

Description

technical field [0001] The present invention relates to a backlight module (Backlight Module), in particular to a direct type backlight module. Background technique [0002] In recent years, liquid crystal displays (Liquid Crystal Displays; LCDs) tend to gradually replace cathode ray tube (Cathode Ray Tube; CRT) displays and become the mainstream of the market. The liquid crystal display panel of the liquid crystal display does not have the function of emitting light. Therefore, a backlight module must be used to provide the surface light source required by the liquid crystal display panel to achieve the function of displaying images. [0003] Backlight modules can be divided into direct-lit backlight modules and side-lit backlight modules. Generally speaking, a direct-lit backlight module includes a backplane, a plurality of lamps and lamp holders, wherein the lamps are arranged on the backboard to provide a light source, and the lamp holders are assembled to the backboard...
