Abstract

The invention belongs to the field of liquid crystal display technical equipment, and particularly relates to a backlight module and a display. The backlight module comprises a supporting structure and a light source structure. The supporting structure comprises a back plate and supporting pieces, the back plate is provided with a containing cavity, and the containing cavity is provided with an opening. The light source structure is located in the containing cavity and comprises a diffusion plate and a lamp panel arranged to project light rays to the diffusion plate, the lamp panel is laid in the containing cavity, the diffusion plate is stacked relative to the lamp panel, an avoiding hole is formed in the lamp panel, one end of each supporting piece penetrates through the avoiding hole and is connected with the cavity bottom of the containing cavity, and the other end of each supporting piece abuts against and supports the diffusion plate, so that the diffusion plate is arranged relative to the lamp panel in a clearance manner; the multiple supporting pieces are arranged at intervals. The diffusion plate can be prevented from being expanded when heated, the OD value of the diffusion plate is guaranteed, meanwhile, light diffusion is guaranteed, and therefore the uniformity of light rays on the diffusion plate is improved.

Description

technical field [0001] The invention belongs to the field of liquid crystal display technical equipment, in particular to a backlight module and a display. Background technique [0002] At present, due to the continuous impact of OLED (Organic Light-Emitting Diode), the LCD (Liquid Crystal Display) industry continues to develop and innovate, and has developed mini LED (light-emitting diode) and micro LED. Mini LED is still LCD backlight technology, but Through the introduction of packaging, size reduction and mass transfer technology, the ability to control the backlight area is improved, the optical distance of the backlight is reduced, and the ultra-thin, high dynamic contrast backlight technology is realized. The introduction of mini LED backlight will help to break through the limitations of LCD, weaken the advantages of self-luminous technology, and further widen the cost performance gap between LCD and alternative technologies. Compared with OLED, mini LED has higher ...
