  • Publication number: 20180364412
    Abstract: The application discloses a backlight module and a display device, and the backlight module includes a light guiding plate, and a light deflector arranged on the side of a light exit face of the light guiding plate, where the light deflector includes a prism module; and the light deflector includes a plurality of light deflecting elements having a same structure, where the respective light deflecting elements are asymmetrically structured inclined from the normal perpendicular to the light exit face of the light guiding plate so that an angle of view of light exiting from the backlight module is deflected from the normal. The prism module includes at least one layer of prism sheet, and there are a plurality of strip-shaped convex prisms arranged in parallel on the surface of the prism sheet away from the light guiding plate.

  • Publication number: 20160103277
    Abstract: The present disclosure provides a backlight module and a display apparatus. The backlight module includes: a substrate configured to fix a plurality of light sources; the plurality of light sources fixed on the substrate and connected electrically to each other; and a light guide plate having at least one side on which a recess portion for receiving the plurality of light sources or receiving the plurality of light sources and at least part of the substrate is provided. At least the plurality of light sources are embedded into the recess portion, thus, the light emitted from the plurality of light sources may enter the light guide plate completely for utilization. Not only the brightness of the backlight module may be improved, but also the energy waste due to the part of the light of the plurality of light sources failing to enter the light guide plate may be avoided.
