A display apparatus including: a display panel including an emission line and a pixel electrically connected to the emission line; an emission driver configured to output an emission signal to the emission line; and a driving controller configured to determine a light emission cycle, wherein the light emission cycle is a number of light emissions in a single frame of the emission signal, wherein the driving controller is configured to determine a luminance according to a user luminance setting and a grayscale value of input image data, to determine the light emission cycle corresponding to a range of the luminance and to determine an off ratio according to the luminance, wherein the off ratio is a ratio of turned-off gate lines to a total number of the gate lines.

Display apparatus and a method of driving a display panel using the same

A gamma voltage generator included in a display device includes a gamma reference voltage storage block configured to store gamma reference voltage values at reference gray levels, an additional offset storage block configured to store additional offset values for the gamma reference voltage values at the reference gray levels, an additional offset setting block configured to store gamma select information representing whether the additional offset values are to be applied or not, a gamma reference voltage calculation block configured to generate final gamma reference voltage values by selectively adding the additional offset values to the gamma reference voltage values depending on the gamma select information, and a gamma reference voltage generation block configured to generate gamma reference voltages corresponding to the final gamma reference voltage values.
