Abstract: The present disclosure relates to a pixel displaying an image. A pixel includes an organic light emitting diode, a first transistor controlling an amount of current flowing from a first driving power supply to a second driving power supply via the organic light emitting diode in response to a voltage of a first node; a storage capacitor connected between the first node and the first driving power supply; a second transistor connected between a data line and the first node and turned on when a scan signal is supplied to a first scan line, and an auxiliary transistor connected between the second transistor and the data line and turned on when a scan signal is supplied to a second scan line. The second transistor and the auxiliary transistor have an overlapping turn-on period, and the second transistor is turned off before the auxiliary transistor is turned off.

Abstract: A display device a display driver configured to drive pixels in correspondence with input image data, timing signals, and a brightness selection signal. The display driver includes a storage unit configured to store gamma data and a duty value for each of a plurality of sample brightness levels including a K-th sample brightness level, and a brightness controller the display driver being configured to control the brightness of the display area according to the gamma data or the duty value or gamma data obtained by non-linearly interpolating gamma data of a (K−1)-th sample brightness level and the K-th sample brightness level, with respect to a tuning point brightness level. A light emission time of the pixels corresponding to the (K−1)-th sample brightness level is less than or equal to 10% shorter than the light emission time of the pixels corresponding to the K-th sample brightness level.
