  • Patent number: 10026351
    Abstract: A timing controller includes a plurality of image enhancement blocks, a plurality of dithering blocks and a random number generating block. The plurality of image enhancement blocks performs image quality enhancement operations for input image data. The plurality of dithering blocks performs random dithering operations for outputs of the plurality of image enhancement blocks based on a plurality of random number tables. The random number generating block generates the plurality of random number tables which is provided to the plurality of dithering blocks.
