  • Publication number: 20240282254
    Abstract: A display device includes a display panel including a plurality of pixels, each of the plurality of pixels including a first color sub-pixel, a second color sub-pixel and a third color sub-pixel, and a panel driver configured to drive the display panel based on input image data. The panel driver stores a gamma curve characteristic to which a color crosstalk offset of the display panel is applied, detects mixed color pixels among the plurality of pixels by analyzing the input image data, determines a compensation coefficient for each of the mixed color pixels based on the input image data for each of the mixed color pixels, and compensates a luminance of each of the mixed color pixels based on the color crosstalk offset and the compensation coefficient.

  • Patent number: 11355052
    Abstract: A display apparatus includes a display panel including a plurality of pixels, and a driver which receives input image data, generates final image data by compensating the input image data to increase luminances of pixels disposed in at least one edge portion of the display panel among the plurality of pixels, and drives the display panel based on the final image data. The input image data for a pixel of the pixels is compensated based on a compensation constant determined according to a position of the pixel when the input image data for the pixel represents a gray level higher than or equal to a first reference gray level, and is compensated based on a reduced compensation constant that is reduced from the determined compensation constant when the input image data for the pixel represents the gray level lower than the first reference gray level.
