    Abstract: A display device includes a processor and a display panel for receiving observation grayscale values from the processor. The display panel includes a data driver for applying data voltages to data lines, a target pixel coupled to at least one of the data lines, and observation pixels each coupled to at least one of the data lines, and located adjacent to the target pixel. The display panel applies a first data voltage to the target pixel, when the observation grayscale values for the observation pixels exceed a reference value. The display panel applies a second data voltage to the target pixel, when at least one of the observation grayscale values does not exceed the reference value. The first data voltage and the second data voltage are different from each other.

    Abstract: A display device includes 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.
