Abstract: 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.
