Problems solved by technology

[0004] Usually, the backlight module set in the liquid crystal display panel includes a backplane, a plastic frame, a lamp board, and an optical film on the light emitting side of the lamp board. When preparing a curved display screen, it is necessary to attach the lamp board to the curved back On the board, the lamp board is forced to be bent in accordance with the curvature of the back board.

Example Embodiment

[0027] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for ease of description, the drawings only show a part but not all of the structure related to the present invention.

[0028] As mentioned in the background section, the existing LCD screens are gradually expanding to curved display screens in application scenarios such as vehicles. In curved display screens, in addition to bending the liquid crystal panel, both the touch panel and the backlight module are required to be processed and bent. For the backlight module, when processing and bending, the rigid back plate is first bent, and then the lamp plate is bent and attached to the back plate. Because the rigidity of the lamp plate and the back plate are inconsistent, and th...

Abstract

Embodiments of the invention disclose a backlight module, a preparation method and a curved display panel. The backlight module comprises a curved backboard, a curved lamp panel and a plurality of fastening structures, wherein the curved lamp panel is the same as the curved contour of the curved backboard; a plurality of light sources are arranged on the surface of one side, deviating from the curved backboard, of the curved lamp panel; and the plurality of fastening structures are used for fixing the curved lamp panel on the curved backboard. According to the embodiments of the invention, a problem that the backlight is not uniform due to the fact that the lamp panel in the existing backlight module is easily peeled off from the backboard is solved, so that the relative positions of the curved lamp panel and the light sources arranged on the curved lamp panel and the curved backboard are fixed, and thus the stability of the uniform backlight of the backlight module is realized, and the display effect of the display panel is ensured.

Description

technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular to a backlight module, a manufacturing method and a curved display panel. Background technique [0002] The backlight module is one of the key components of the liquid crystal display panel. Its function is to supply sufficient brightness and evenly distributed light source so that it can display images normally. The traditional liquid crystal display panel has a flat panel structure, and the backlight module also adopts a flat structure to provide backlight. [0003] With the development of display technology, the applicable scenarios of liquid crystal display panels are gradually expanding. For fields such as automotive display screens, the structure of the liquid crystal display panel needs to be adjusted adaptively, for example, it is necessary to prepare a curved vehicle display screen that adapts to the application environment. The assembly pro...
