The invention relates to a display device and a method of driving a display device, wherein the display comprises a plurality of light emitting elements and means for applying a driving signal to the light emitting elements. The display device comprises control means for adjusting a duty cycle and a magnitude of the driving signal for at least one of the light emitting elements. In this way the uniformity of the display can be controlled while keeping the brightness of the display constant. Control of the uniformity of the display may e.g. be used in relation to control of the power consumption of the display device or improving the quality of dark images.
