Abstract: A display device includes a display panel including a plurality of pixels, a current sensor that senses a sensing current that flows through the pixels, and a data compensator. The data compensator calculates a target current from an image frame of input image data using a current deviation for each position of the image frame and a current contribution ratio for each color of the image frame, and that generates a scale factor by comparing the target current and the sensing current. The display device further includes a timing controller that generates output image data by scaling grayscale values of the input image data using the scale factor; and a data driver that provides a data signal corresponding to the output image data to the pixels.

Abstract: A display device includes a display panel and a display panel driver. The display panel includes pixels. The display panel driver determines an average image load of input image data, determines an operation mode based on a grayscale value of the input image data and the average image load as a first operation mode or a second operation mode, applies a first scale factor to the input image data in the first operation mode, applies a second scale factor different from the first scale factor to the input image data in the second operation mode, and drives the display panel.
