Problems solved by technology

In related technologies, the backlight modules of large-size LCD displays are mostly composed of multiple Mini LED light panels, and during the assembly process of multiple light panels, there are gaps at the joints of adjacent light panels, and due to the dimensional tolerance of the light panels Factors such as the alignment tolerance and the alignment tolerance of the light board assembly will cause shadows in the gaps between adjacent light boards, thereby affecting the display effect of the display panel and the display device

Abstract

The embodiment of the invention provides a backlight module, a display panel and a display device. The backlight module comprises a back plate, at least two lamp panels, a diffusion plate and a light adjusting structure. Wherein the at least two lamp panels are arranged on one side of the back panel, a gap is formed between every two adjacent lamp panels in the at least two lamp panels, and at least one lamp bead is arranged on each lamp panel; the diffusion plate is arranged on the sides, away from the back plate, of the at least two lamp panels. The light adjusting structure is arranged on the side, away from the back plate, of the diffusion plate, the orthographic projection of the light adjusting structure on the at least two lamp panels covers the gap and at least partially covers at least one lamp bead on the at least one lamp panel, and the light adjusting structure is configured to increase the light intensity in the gap.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a backlight module, a display panel and a display device. Background technique [0002] This section provides background information only related to the present application and is not necessarily prior art. [0003] Mini LED (Mini Light-Emitting Diode, Mini Light Emitting Diode) backlight is widely used in large-size LCD (Liquid Crystal Display, liquid crystal display) displays due to its high brightness, high contrast ratio, and thin size. In the related art, the backlight modules of large-size LCD displays are mostly composed of multiple Mini LED lamp panels. During the assembly process of the multiple lamp panels, there is a gap between the connections of the adjacent lamp panels, and due to the dimensional tolerance of the lamp panels. Factors such as the alignment tolerance during assembly of the lamp panels will cause shadows to occur in the gaps between ad...
