Abstract

The invention relates to the technical field of display equipment, and discloses a lamp panel, a backlight module and a display device. The lamp panel comprises a flexible circuit board which comprises a first side face and a second side face; a light source which is positioned on the first side surface of the flexible circuit board; a supporting plate which is located on the second side face of the flexible circuit board and comprises a plurality of supporting parts capable of being spliced in sequence, each supporting part is of a strip-shaped structure, and the side, close to the flexible circuit board, of each supporting part is connected with the second side face of the flexible circuit board; wherein the flexible circuit board can be bent in the arrangement direction of the pluralityof supporting parts; when the flexible circuit board is in a flattened state, the sides, away from the flexible circuit board, of the multiple supporting parts are flatly spliced. When the flexible circuit board is in a bent state, the sides, away from the flexible circuit board, of the multiple supporting parts are disconnected. According to the lamp panel, the bending stress can be reduced, good attachment between the lamp panel and the back plate is guaranteed, the light source light mixing distance is not changed, and then the problem that the display brightness of the curved display panel is uneven due to the bending stress problem is solved.

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] Such as 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 bendin...
