Abstract: A driving method for dimming an organic light-emitting diode (OLED) display is disclosed. In one aspect, the method includes selecting a dimming mode indicating a maximum luminance to be displayed by the OLED display based on an input and determining a luminance range from a plurality of luminance ranges. The determined luminance range comprises the maximum luminance of the dimming mode. The method also includes performing at least one of converting image data based at least in part on the dimming mode or controlling a duty ratio of an emission control signal, wherein the performing is based at least in part on the determined luminance range.
