Abstract: A display apparatus includes a display panel, an afterimage compensator and a data driver. The display panel displays an image. The afterimage compensator writes first stress data of input image data corresponding to a first area to a first memory area in a first block size and second stress data of the input image data corresponding to a second area to a second memory area in a second block size different from the first block size and compensates a grayscale value of the input image data based on the first stress data and the second stress data. The data driver generates a data voltage based on a compensated grayscale value and outputs the data voltage to the display panel.

Abstract: A display panel driver includes: a driving controller receiving input image data and converting the input image data into a data signal and a data driver converting the data signal into a data voltage. The driving controller includes a plurality of lookup tables storing data signal values corresponding to grayscale values of the input image data based on an input maximum luminance, and a total number of the data signal values stored in a first lookup table corresponding to a first input maximum luminance is different from a total number of the data signal values stored in a second lookup table corresponding to a second input maximum luminance.

Abstract: A display device includes: a display panel including a first region having a first pixel structure and a second region having a second pixel structure different from the first pixel structure, and a display panel driver configured to render first region data corresponding to the first region among input image data to generate rendering data in an inactive period of a data enable signal, and to generate data voltages applied to the first region based on the rendering data in an active period of the data enable signal.
