Abstract
A display device includes a display panel including pixels connected to emission lines, a controller configured to receive a control signal, and to generate an emission start signal, a first emission clock signal and a second emission clock signal, and an emission driver configured to provide emission signals to the pixels through the emission lines in response to the emission start signal, the first emission clock signal and the second emission clock signal. The controller is further configured to determine an off period ratio for the pixels in units of two or more frame periods in response to the dimming signal. The control signal may be a dimming signal, a low power mode signal, or another type of signal indicative of operation of the display device.
