Problems solved by technology

[0003] The curved surface display device is equipped with a curved surface backlight module to provide a light source for the curved surface display device. The curved surface backlight module has a backplane and a light board. There is curvature in the back panel. When the light panel and the back panel are assembled and bonded, the light panel is easy to separate from the back panel in the area with a large curvature of the back panel, resulting in inconsistent light mixing height of the curved backlight module, causing the curved display device to emit light. uneven

Abstract

The present invention relates to the field of display technologies, and particularly relates to a backlight module and a display apparatus. The backlight module comprises a curved-surface backplane and a backlight lamp panel. The backlight lamp panel is disposed on one side of the curved-surface backplane, and fits the curved-surface backplane. The backlight lamp panel comprises at least two sub-lamp panels. The sub-lamp panel comprises a body and at least one connection part disposed on one side of the body. Adjacent sub-lamp panels are rotatablely connected by using the connection part, so that the adjacent sub-lamp panels bend along a bending direction of the curved-surface backplane. The backlight module provided in the present invention, the backlight lamp panel comprises at least twosub-lamp panels, adjacent sub-lamp panels are rotatablely connected by using the connection part, so that a stress generated during bending of the backlight lamp panel is released, and stress concentration generated during bending of the backlight lamp panel is avoided, thereby effectively reducing a probability that the backlight lamp panel separates from the curved-surface backplane, and ensuring highly consistent mixed light in a mixed light region of the display module. Therefore, even lighting output of the backlight module is ensured, and structure stability and a service life of the display apparatus are enhanced.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a backlight module and a display device. 【Background technique】 [0002] In recent years, due to its excellent viewing angle and human visual experience, curved display devices have broad application prospects and good market potential in televisions, automobiles and other fields, and have attracted widespread attention. [0003] The curved surface display device is equipped with a curved surface backlight module to provide a light source for the curved surface display device. The curved surface backlight module has a backplane and a light board. There is curvature in the back panel. When the light panel and the back panel are assembled and bonded, the light panel is easy to separate from the back panel in the area with a large curvature of the back panel, resulting in inconsistent light mixing height of the curved backlight module, causing the curved display device to emit li...
