Abstract: A display device comprises a display area including a plurality of pixels, a peak driving determination part determining peak driving based on an input image signal, a normal driving compensation part including a first luminance lookup table having a first luminance as a peak luminance, a peak driving compensation part including a second luminance lookup table having a second luminance higher than the first luminance as a peak luminance, a compensation adjusting part that generates a peak driving gamma curve by smoothing a first and second luminance gamma curves corresponding to the first and second luminance lookup tables and generates a peak driving lookup table according to the peak driving gamma curve, and a signal controller generating an image data signal by applying one normal driving lookup table to a portion of the display area and applying the peak driving lookup table to an other portion of the display area.

Abstract: Provided herein may be a display device. The display device may include a display panel including a plurality of unit blocks disposed in a display area, the plurality of unit blocks including a first area displaying a logo or a banner, a second area having largest load value and a third area disposed between the first area and the second area, a display panel driver configured to generate data voltages based on input image data, and a zonal compensator configured to receive the input image data, to calculate load values of the input image data for the plurality of unit blocks, respectively, and to control luminance of each of the first area and the third area based on a location difference between the first area and the second area and a load value difference between the first area and the second area.
