Problems solved by technology

[0003] A mini-LED display is usually composed of a backplane, a mini-LED light source, a diffusion plate, an optical film, a plastic frame, a liquid crystal panel, and a front frame. Slight deformation of the part will affect the OD (optical distance, optical distance) value, and will also reduce the distance between the diffuser plate and the mini-LED light source, causing the diffuser plate to expand due to heat

Abstract

The invention discloses a backlight module and a display device. The backlight module comprises a lamp panel, a diffusion plate and an optical film which are sequentially stacked, wherein a plurality of lamp beads distributed at intervals are arranged on the surface, facing the diffusion plate, of the lamp panel; the backlight module further comprises a plurality of supporting columns, the supporting columns are arranged between the diffusion plate and the lamp panel, one ends of the supporting columns are connected with the diffusion plate, and the other ends of the supporting columns are located between the adjacent lamp beads; and the cross section area of one end, corresponding to the diffusion plate, of each supporting column is larger than that of one end, corresponding to the lamp panel, of the supporting column. By means of the backlight module and the display device, the lamp beads on the lamp panel can be prevented from making contact with the diffusion plate, the diffusion plate is prevented from expanding due to heating, the optical distance value is guaranteed, light loss is avoided, and the utilization rate of a light source is increased.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a backlight module and a display device. Background technique [0002] At present, as a cold light source, a light emitting diode (Light Emitting Diode, LED) has the advantages of environmental protection and energy saving, and has been widely used in lighting. At the same time, LEDs are gradually being used in the field of display panels, such as LED screen billboards, due to their high brightness, long life, and wide viewing angles. In particular, the application of mini light-emitting diodes (mini-LEDs) in the field of display lighting has become a recent research hotspot and has attracted the attention of major panel manufacturers. [0003] A mini-LED display is usually composed of a backplane, a mini-LED light source, a diffusion plate, an optical film, a plastic frame, a liquid crystal panel, and a front frame. The slight deformation of the part will affect the...
