Abstract
In a display device that changes the number of light emissions per frame period, a display control circuit outputs a control signal specifying an emission period included in a frame period to an emission control line driver circuit. The emission control line driver circuit adds sequential delays to the control signal and thereby generates signals to be applied to the emission control lines. When leading and trailing frame periods have the same proportion of emission periods but include different numbers of emission periods, the leading and trailing frame periods are intervened by a transition frame period having a different proportion of emission periods from the leading frame period. This configuration prevents flickering caused by the changing of the number of light emissions per frame period.
