1. A display device comprising:
a display unit including a plurality of pixel rows connected to at least one data line,
a plurality of scan lines and a plurality of emission control lines;
a controller configured to determine a width of a gate-off section of an emission control signal in response to a dimming signal,
wherein the gate-off section of the emission control signal corresponds to a non-emission section of any one of a plurality of frames; and an emission driver configured to supply the emission control signal to the plurality of pixel rows through the plurality of emission control lines,
wherein the dimming signal includes information on a dimming level corresponding to display luminance of the display unit,
wherein the controller determines the width of the gate-off section of the emission control signal corresponding to a first reference dimming level as a first width, and determines the width of the gate-off section of the emission control signal corresponding to a second reference dimming level as a second width,
the first reference dimming level being higher than the second reference dimming level,
wherein in response to the dimming signal in which the information on the dimming level is a first intermediate dimming level, the controller determines the width of the gate-off section of the emission control signal supplied to at least one among the plurality of frames as the first width, and the width of the gate-off section of the emission control signal supplied to a rest of the plurality of frames as the second width,
wherein the first intermediate dimming level is a value between the first reference dimming level and the second reference dimming level, and
wherein an average of the widths of all gate-off sections of the emission control signal per frame in the plurality of frames corresponds to the width of the gate-off section indicated by the first intermediate dimming level.
