Abstract

The invention relates to the technical field of display equipment, and discloses a lamp board, a backlight module and a display device. The lamp board includes a flexible circuit board, including a first side and a second side; a light source is located on the first side of the flexible circuit board; The support plate is located on the second side of the flexible circuit board and includes a plurality of support parts that can be spliced ​​in sequence. The support parts are strip-shaped structures, and the side of each support part adjacent to the flexible circuit board is connected to the second side of the flexible circuit board; Wherein, the flexible circuit board can be bent in the arrangement direction of multiple supporting parts; when the flexible circuit board is in a flattened state, the side of the multiple supporting parts away from the flexible circuit board is flatly spliced; when the flexible circuit board is in a bent state, The side of the plurality of supporting parts away from the flexible circuit board is unspliced. The lamp panel can reduce the bending stress, ensure the good attachment of the lamp panel and the back panel, and keep the light mixing distance of the light source unchanged, thereby solving the problem of uneven display brightness of the curved display panel caused by the bending stress.

Description

technical field [0001] The invention relates to the technical field of display equipment, in particular to a lamp panel, a backlight module and a display device. Background technique [0002] At present, curved display screens are frequently used in fields such as vehicle display screens. The slope of the car curved display is currently required to be R700~R1000. When making a curved display, the curved display panel is bent and bonded to the packaging glass. The backlight module includes the backplane and the light board attached to the backplane. The back panel is directly bent and formed by a mold, and the light panel is generally a flat plate, which needs to be bonded to the curved back panel. [0003] like figure 1 as shown, figure 1 It is a structural schematic diagram of a lamp board and a back board bonding in the prior art. When the lamp board 01 is attached to the curved back board 02, the lamp board 01 will be subjected to the stress generated by the bending. ...
