Embodiment Construction
[0029] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments. Apparently, the described embodiments are some, not all, embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0030] Such as image 3 As shown, it is a schematic structural diagram (left view) of a backlight module according to an embodiment of the present invention. The backlight module is used in a 2D / 3D display device. The backlight module of this embodiment includes: a plurality of first light sources 1 and diffuser plate 2, the first light source array arrangement (such as figure 2 shown), in the 3D display mode, the plurality of first light s...

The invention belongs to the field of display technology, and discloses a backlight module and a display device. The backlight module includes: a plurality of first light sources and a diffusion plate. In a 3D display mode, the plurality of first light sources belong to different Scanning area, each scanning area corresponds to a display area, the backlight module further includes: a blocking structure corresponding to each scanning area, used to block the light emitted by the first light source in other scanning areas except the current scanning area The light is transmitted to the display area corresponding to the current scanning area. The backlight module of the present invention is provided with a blocking structure corresponding to each scanning area, which prevents the light emitted by the first light source in other scanning areas from being transmitted to the display area corresponding to the current scanning area, and reduces the time when the 3D display backlight source scans. The amount of light entering from the light-on scanning area to the light-off scanning area reduces crosstalk during 3D display and improves the quality of stereoscopic display.
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...
