Abstract: A display device may include a display panel including pixels, and a display panel driver which drives the display panel. The display panel driver determines whether input image data displays a white image and whether the input image data displays a moving image, and adjusts an input saturation value of the input image data based on whether the input image data displays the white image and whether the input image data displays the moving image to generate correction image data.

Abstract: In a method of compressing stress data in a display device, the stress data is divided into block stress data for a pixel block, a plurality of compressed codes are generated by encoding the block stress data in a plurality of encoding modes, it is determined whether the plurality of encoding modes are available encoding modes for the block stress data based on code lengths of the plurality of compressed codes and a number of available bits for the pixel block, a final encoding mode is selected among the available encoding modes based on quantization values of the available encoding modes, and a compressed bitstream for the pixel block is generated based on a compressed code corresponding to the final encoding mode among the plurality of compressed codes.

Abstract: A display device divides a display panel into a skin region and a non-skin region different from the skin region based on input image data, calculates a saturation weight of the skin region and a saturation weight of the non-skin region, calculates the saturation weight of the non-skin area based on the input image data, and calculates a value weight and a hue weight based on the input image data. The saturation compensation value is determined based on a saturation value of the input image data, the saturation weight, the value weight, and the hue weight, and a value compensation value is determined based on a value value of the input image data. The input image data is compensated based on the saturation compensation value and the value compensation value.
