Abstract

The embodiment of the invention discloses a backlight module and a curved-surface display device. The backlight module comprises a frame, a light guide plate, a back plate, a circuit board and multiple lamp sources; the light guide plate is arranged in the frame; the back plate is arranged between the light guide plate and the inner wall of the frame; the circuit board is not arranged on the lightexiting surface of the light guide plate, and at least one convex portion used for clamping the light guide plate is arranged at the edge of the circuit board; and the lamp sources are correspondingly arranged on the light entering side of the light guide plate and electrically connected with the circuit board. The convex portions used for clamping the light guide plate are arranged at the edge of the circuit board, therefore, the edge of the light guide plate is clamped after the light guide plate is bent, the light entering side of the light guide plate always keeps aligned with the lamp sources, resilience of the light guide plate is prevented, normal light entering is guaranteed, and then the problems that uneven brightness and local spot defects are generated are avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a curved display device. Background technique [0002] Curved displays have been widely used in various fields. The curved displays not only increase the aesthetics of the displays, but also improve the user's visual experience. [0003] Curved displays need to be bent during production, and after bending, there will often be misalignment between the light guide plate of the display device and the light source, which will easily lead to abnormal light incident, uneven brightness, and local spot defects, etc. question. Contents of the invention [0004] Embodiments of the present invention provide a backlight module and a curved display device, which can avoid the problem of abnormal light incident caused by bending the panel. [0005] On the one hand, an embodiment of the present invention provides a backlight module, which includes: [0006] light gu...
