Abstract

See full text

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.
