  • Publication number: 20230133405
    Abstract: A display device includes a display panel including a plurality of sub-pixels arranged in a first pixel arrangement structure, and a display driver which receives input image data corresponding to a second pixel arrangement structure different from the first pixel arrangement structure. In a normal driving mode, the display driver generates first output image data for all of the plurality of sub-pixels by performing a first rending operation on the input image data, and drives all of the plurality of sub-pixels based on the first output image data. In a low power driving mode, the display driver generates second output image data for a portion of the plurality of sub-pixels by performing a second rending operation different from the first rending operation on the input image data, and drives the portion of the plurality of sub-pixels based on the second output image data.

  • Publication number: 20220262318
    Abstract: A display device includes dots and a grayscale correction unit. Each dot among the dots includes a first pixel of a first color, a second pixel of a second color, and a third pixel of a third color. The grayscale correction unit is configured to generate corrected grayscale values for a target dot via application of weights to grayscale values of the target dot and grayscale values of neighboring dots of the target dot among the dots. The grayscale correction unit is configured to determine the weights based on the grayscale values of the target dot.
