Problems solved by technology

However, due to the limitations of the manufacturing process of large-size display panels (usually larger than 65 inches), it is extremely difficult to use a light board for backlight design, and it is not conducive to later assembly
[0003] The backlight design of the large-size display panel in the prior art is made by designing the lamp board into multiple small pieces for splicing and assembling. Due to the design assembly gap, there will inevitably be gaps between the lamp boards
When the module is in some extreme working conditions such as assembly, handling, reliability test (such as dropping), vehicle transportation, etc., the gap between the light boards will inevitably become smaller, which will easily cause the light boards to interfere with each other and break

Abstract

The invention provides a backlight module and a display device. The backlight module comprises a back plate and a lamp panel arranged on the back plate, and the lamp panel comprises a plurality of lamp panel blocks; wherein a buffer device is arranged in a gap of the lamp panel block, the buffer device is divided into a transverse component and a longitudinal component, the transverse component islocated in a row gap of the lamp panel, and the longitudinal component is located in a column gap of the lamp panel. According to the invention, the buffer device is arranged in the gap of the lamp plate block, so that the lamp plate block can be effectively prevented from being broken due to interference caused by deformation of the module, and the lamp plate block can be accurately positioned and assembled.

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 development of the liquid crystal display panel and backlight module industry, the mainstream trend of backlight design in the backlight module is also constantly changing. There are many benefits to using mini LEDs, such as reducing and controlling costs, achieving smaller light coupling distance and better color contrast, and realizing ultra-thin module structure design, etc. However, due to the limitations of the manufacturing process of large-size display panels (usually larger than 65 inches), it is extremely difficult to use a light board for backlight design, and it is not conducive to later assembly. [0003] The backlight design of the large-size display panel in the prior art is made by designing the lamp boards into multiple small pieces for splicing and assembling. Due to the desig...
