Abstract

The invention belongs to the technical field of liquid crystal display equipment, and particularly relates to a backlight device and a display. The backlight device includes a support structure and a light-emitting structure. The supporting structure comprises a back plate, and a mounting cavity is formed in the plate face of one side of the back plate. The light-emitting structure comprises a total reflection layer and lamp panels located in the mounting cavity, the lamp panels are connected with the cavity bottom of the mounting cavity and provided with light-emitting faces, the light-emitting faces are arranged back to the cavity bottom of the mounting cavity, the total reflection layer is made of light-transmitting materials and coated on the light-emitting faces, the lamp panels are flatly laid relative to the cavity bottom of the mounting cavity and sequentially spliced, a splicing seam is formed between the edges of any two adjacent lamp panels, the light-emitting structure further comprises seam filling strips, the seam filling strips comprise seam filling layers and glue sealing layers, each seam filling strip is arranged in each corresponding splicing seam, and one ends of any two adjacent seam filling strips are connected at the junction of the two corresponding splicing seams. Splicing seams at the splicing positions of the lamp panels can be eliminated, and imperfect pictures caused by splicing of the display are effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display equipment, and in particular relates to a backlight device 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 (Mini Light-Emitting Diode) and micro LED (micro Light-Emitting Diode), mini LED It still belongs to 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 alternativ...
