Backlight module and display device

Abstract

The invention provides a backlight module and a display device. The backlight module comprises a back plate and a supporting seat, wherein the back plate comprises a bottom plate, a side plate and a lug, and the lug is provided with a first through hole; the supporting seat comprises a chamfer and a supporting plate; the chamfer extends to the interior of the supporting seat from the side face of the supporting plate facing the side plate; a top plate is arranged above the chamfer and provided with a second through hole corresponding to the first through hole; the supporting plate is arranged on the side wall forming the chamfer and parallel to the top plate, and the supporting plate, the top plate and the side wall form an accommodating area and an opening; and the lug is inserted in the accommodating area and combines and fixes the supporting seat and the back plate through a fixing piece, the first through hole and the second through hole. The lug of the back plate of the backlight module is arranged in the accommodating area of the supporting seat and supported by the supporting plate so that the lug is not easy to generate displacement caused by the action of external force during locking and fixing a bolt, and the locking and fixing of the lug with a lamp holder and a frame is not easy to generate a misplacement condition so as to be beneficial to assembling and improving the product yield.

Description

technical field [0001] The invention relates to a backlight module and a display device, in particular to a backlight module and a display device capable of preventing deformation of a backplane. Background technique [0002] A general liquid crystal display device requires a backlight module to provide a light source. The backlight module usually includes a lamp holder and a back plate. The lamp holder is used to fix the light source. The brightness and luminance can be adjusted to provide a light source for the liquid crystal display device. [0003] See figure 1 and figure 2 , figure 1 Shown is a schematic diagram of a display device in the prior art, figure 2 shown as figure 1 The schematic cross-sectional view of the assembled display device along line AA' in . The existing liquid crystal display device 1 includes a front frame 2, a liquid crystal panel and a backlight module. The liquid crystal panel is assembled between the front frame 2 and the backlight modu...

Problems solved by technology

[0004] However, in actual operation, since there is no supporting part under the lug 11 of the back plate 4 in the prior art, the structural strength is relatively weak, so during the riveting screw 14 and the handling process, the lug 11 will be deformed due to external force. Deformation, such as when the screw is locked due to the misalignment of the hole position, the lug 11 is bent under pressure (such as figure 2 As shown), it will result in that the screw 14 cannot be smoothly screwed into the first through hole 12 of the lug 11 of the back plate 4. If the front frame 2 is forcibly pulled to align the first through hole 12 and the screw 14, it may cause The deformation of the front frame 2 may cause the panel to crack when the liquid crystal panel is subsequently assembled.
