  • Publication number: 20120327140
    Abstract: An LCD for reducing motion blur includes a display panel, a source driver, a gate driver, and a timing controller. The display panel includes a plurality of pixels for display an image data. The timing controller includes a timing control unit and a data processing unit. The timing control unit controls the timing of the image data outputting to the source driver and the gate driver. The data processing unit analyzes the image data so as to insert black gray-level for the different pixels of the plurality of pixels in the different frames.

  • Patent number: 8125436
    Abstract: A pixel dithering driving method and a timing controller using the same are provided. The method uses the N low order bits of M bits together with at least one virtual bit to build several pixel dithering patterns. After the timing controller uses M bits of data received by the timing controller to look up a specific high order bit value, a specific low order bit value, and a specific pixel dithering value corresponding to the M bits in a predetermined gray level look up table and decides the output gray levels according to the specific high order bit value, the timing controller can further select a specific pixel dithering pattern from the pixel dithering patterns mentioned above according to the specific low order bit value and the specific pixel dithering value.
