Abstract: A display apparatus comprises: a display panel including pixels that emit light, wherein an amount of emitted light is controlled based on a data voltage, and an emission time of the pixels is controlled based on a duty ratio of an emission control signal applied to the pixels; a timing controller configured to control the emission control signal in an active period of one frame and in a blank period of the one frame, where the data voltage is supplied to the pixels during the active period of the one frame and the data voltage is maintained during the blank period of the one frame; and a gate driver configured to apply to the pixels the emission control signal having a first duty ratio during the active period and the emission control signal having a second duty ratio that is different from the first duty ratio during the blank period.
