  • Method for outputting grayscale data, driving controller and display apparatus
    Patent number: 12205509
    Abstract: A method for outputting a grayscale data, a driving controller, and a display apparatus are provided. The method includes: in response to receiving a first input grayscale data which is not greater than a first threshold, generating a first output grayscale data without performing a dither computing on the first input grayscale data and outputting the first output grayscale data; in response to receiving a second input grayscale data which is greater than a second threshold, generating a first dithered grayscale data by performing a first dither computing on the second input grayscale data and outputting the first dithered grayscale data as a second output grayscale data. The second threshold is greater than the first threshold, and the second output grayscale data does not comprise any part of the second input grayscale data not processed by the first dither computing.

  • Image processing circuit and image processing method thereof
    Patent number: 11501687
    Abstract: An image processing circuit is provided. The image processing circuit includes a dither computing circuit and a blending circuit. The dither computing circuit performs a dither computing on the input grayscale data to generate a dithered grayscale data. The blending circuit receives the input grayscale data and the dithered grayscale data, generates a blending weight by comparing the input grayscale data with a first threshold, and performs a blending computing on the input grayscale data and the dithered grayscale data based on the blending weight to output an output grayscale data.
