Abstract: A display device and a driving method is disclosed. The driving method includes receiving an image signal for one frame for one pixel, converting the image signal into at least two data voltages according to at least two gamma curves, applying a first gate signal and a second gate signal to a plurality of gate lines respectively connected to a plurality of subpixels included in one pixel during the frame. The method further includes applying the at least two data voltages to the plurality of subpixels during the frame. A gamma curve for the data voltage applied to one subpixel among the plurality of subpixels includes the at least two different gamma curves and is changed with a period of a first time.

Abstract: A display device includes a display panel having pixels. A timing controller generates a first control signal and data control signals. Data driving circuits each recover a data signal from a corresponding data control signal of the data control signals in response to the first control signal, generate a data voltage corresponding to the data signal, and provide the data voltage to the display panel. Each of the data driving circuits includes: a setting unit configured to acquire a setting value from the data control signal; an equalizer configured to compensate for distortion of the corresponding data control signal according to the setting value to output compensated data control signal; and a recoverer configured to recover a clock signal from the compensated data control signal and recover the data signal from the compensated data control signal based on the clock signal.
