A row-select circuit (118) for an organic light emitting diode display (116) propagates a gating pulse through a shift register. This gating pulse is synchronized with a system clock signal and is used to selectively apply a plurality of broadcast control signals to a selected row of pixels on the display (116). The line scanning circuitry (118) is controlled to clear and autozero the pixels in the display (116) either on line at a time or the entire image frame at a time. According to another aspect of the invention, the clearing of a row of pixels in the display (116) is performed over several line intervals before the row is autozeroed and loaded with new values. According to yet another aspect of the invention, the broadcast control signals may be adapted to achieve the best performance for each display device.
