Backlight module, preparation method and curved display panel

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...

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. Since both the lamp board and the back board have a certain rigidity, the bent lamp board and the back board are easy to peel off each other due to the increase of local bending stress. At this time The peeled light board is easy to move, which causes the distance of the light source on it to change, which makes the backlight of the display panel uneven and affects the display effect of the display panel
