Abstract

The invention belongs to the technical field of display, and discloses a backlight module and a display device. The backlight module comprises a plurality of first light sources and a diffusion plate. In the 3D display mode, the multiple first light sources belong to different scanning regions, and each scanning region corresponding to one display region. The backlight module further comprises blocking structures which are arranged corresponding to the scanning regions, wherein the blocking structures are used for blocking light emitted by the first light sources in other scanning regions except the current scanning region from being transmitted to the display region corresponding to the current scanning region. According to the backlight module, the blocking structures are arranged corresponding to the scanning regions, the light emitted by the first light sources in other scanning regions is blocked from being transmitted to the display region corresponding to the current scanning region, the light inlet amount of the light turning-on scanning region to the light turning-off scanning region is reduced when a backlight source conducts scanning in the 3D display process, crosstalk in the 3D display process is reduced, and 3D display quality is improved.

Description

technical field [0001] The invention relates to the display field, in particular to a backlight module and a display device. Background technique [0002] In the time-division stereoscopic display method (such as SG3D, Real D3D display technology), it is necessary to cooperate with the scanning of the backlight source to achieve high-quality display. The usual practice is to divide the backlight into multiple scanning areas, each scanning area has multiple light sources, and the light sources in one scanning area have the same turn-on and turn-off time to ensure that the turn-on time of the light source in each scanning area matches the panel's display, and turn off the lights in the corresponding scanning area after the display is complete. [0003] For the side-type backlight structure, the lens-type diffuser plate is used as the light transmission surface, which can effectively control the directivity of the light source transmission in the scanning area. In the traditi...
