  • Patent number: 9424784
    Abstract: The present invention discloses a local backlight brightness adjustment method for a direct backlight in a display device, the method comprising the steps of: step 1: performing edge detection on an input image to determine whether a sensitive zone exists, the sensitive zone being a portion in the input image in which a gray level difference between adjacent pixels is greater than a predetermined threshold; and Step 2: if a sensitive zone exists, performing a backlight brightness adjustment with respect to a backlight region corresponding to the sensitive zone and a remaining backlight region other than the backlight region corresponding to the sensitive zone, respectively.

  • Patent number: 9389446
    Abstract: 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.
