The light guide plate having at least one side for placing a light source assembly comprising a plurality of light source units, wherein a plurality of microstructure protrusions are provided on the inner side of the bottom surface of the light guide plate, in regions close to the light source assembly, and the microstructure protrusions are provided with at least one reflective surface, which faces toward the regions of the light guide plate corresponding to the gaps between the light source units. | 04-17-2014 |
20140160393 | FRAME ASSEMBLY AND LIQUID CRYSTAL DISPLAY DEVICE - There are disclosed a frame assembly and liquid crystal display device for reducing leakage of light around a liquid crystal panel and improving display quality of the liquid crystal display device. The frame assembly includes a backboard in which a receiving portion is formed, a front frame mounted on the backboard around an periphery of the backboard and a buffer frame provided between the backboard and the front frame, wherein the backboard is provided with a first support portion, which is folded from a periphery of the backboard towards inside of the receiving portion so as to support the buffer frame. With the backboard of the above configuration, the support stability for the glue frame can be increased, and the deformation of the glue frame under a reaction force from the liquid crystal panel can be reduced, thereby reducing leakage of light around the liquid crystal panel and improving a display quality of the liquid crystal display device. | 06-12-2014 |
20150241720 | Backlight Module and Display Device - The present invention relates to a backlight module for providing light to a liquid crystal panel and a display device. The backlight module comprises an optical membrane material arranged at a back surface of the liquid crystal panel, and a module frame surrounding the optical membrane material. An end surface of the module frame facing the liquid crystal panel is located at the back surface of the liquid crystal panel, and the module frame supports the liquid crystal panel through the end surface. The display device comprises a liquid crystal panel and the backlight module. According to the present invention, the end surface of the module frame facing the liquid crystal panel is located at the back surface of the liquid crystal panel. As a result, it is able to provide a very narrow end surface of the module frame, thereby to narrow a bezel of the display device. | 08-27-2015 |
20150253490 | Light guide Plate, Backlight Module and Liquid Crystal Module - The present disclosure discloses a light guide plate, a backlight module and a liquid crystal module. The light guide plate includes a plurality of light guide blocks; the light guide blocks are doped with scattering particles. Since the light guide plate includes a plurality of light guide blocks, this can simplify the cutting of the light guide plate and the making of grid points. The light guide blocks are doped with scattering particles, so that most of rays incident upon the light guide blocks are scattered in a preset direction and guided to a middle part and the light-far end of the backlight module to compensate the brightness of the middle part and the light-far end, thus making the brightness of the side light type backlight display uniform. | 09-10-2015 |
