Backlight module and display device

Abstract

The invention discloses a backlight module and a display device. The backlight module comprises a back plate, a lamp panel, a diffusion plate and a plurality of groups of silk thread assemblies, wherein the back plate comprises a bottom plate and a plurality of side plates which are arranged on the peripheral side of the bottom plate in a surrounding mode and are perpendicular to the bottom plate, and the side plates and the bottom plate are matched to form a containing space with an opening in the side away from the bottom plate; the plurality of groups of silk thread assemblies are located between the diffusion plate and the lamp panel, each group of silk thread assemblies comprises a plurality of silk threads, each silk thread penetrates through the opening of the accommodating space of the back plate and is tensioned on the side plate of the back plate, the plurality of groups of silk thread assemblies are mutually matched to form a support body for supporting the diffusion plate assembly, the plurality of groups of silk thread assemblies support diffusion, the effective visual angle of a product can be improved, the frameless / narrow-frame design can be conveniently achieved, the overall mass of the display device is reduced, meanwhile, a larger and more dispersed supporting face is achieved, and the failure risk of the diffusion plate during mechanical vibration is effectively reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a display device. Background technique [0002] With the rapid progress of liquid crystal display (liquid crystal display, referred to as LCD) production technology, and its advantages of thinness, lightness, power saving and no radiation, liquid crystal displays are widely used in notebook computers, digital cameras, and digital video recorders. , mobile phones, computer screens and LCD TVs and other electronic products. However, since the liquid crystal display panel in the liquid crystal display is a non-self-illuminating display panel, the display function needs to be provided by the light source provided by the backlight module. [0003] Commonly used backlight modules include edge-type backlight modules and direct-type backlight modules. In the direct-lit backlight module, considering the current technical level and cost, the distance between the l...

AI Technical Summary

Problems solved by technology

As the arrangement of lamp beads on the lamp board becomes tighter and tighter, the layout space and structural strength of the bracket cannot meet the demand, and it is easy to fall off during mechanical vibration, and because it is a point support, it is easier to wear the DP, resulting in poor picture
