A display device comprises a display panel having a plurality of pixels for emitting light disposed on an active area of the display panel. The pixels may be grouped into a plurality of subsets, each subset of pixels coupled to a corresponding power line. The subsets of pixels may be programmed and operated in succession in a rolling configuration. The power line may be configured to provide a low supply voltage to turn on the corresponding subset of pixels, or a high supply voltage to turn off the corresponding subset of pixels. By turning off each subset of pixels when the subset is not being programmed or controlled to emit light, a picture quality of the display may potentially be improved, by preventing leakages or tailing effects in the non-emitting pixels when of the display.
