Abstract
A method for driving a dark ring of a liquid-crystal-on-silicon (LCOS) display is provided to prevent the fringe effect (bright lines) due to the constant voltage difference between the dark ring and the adjoining pixels within the LCOS display. A dark ring is divided into a plurality of portions. The polarity of each portion is controlled in accordance with the polarity of the adjoining pixels within the LCOS display and the scan direction of gate drivers such that the polarity inversion for each portion will coincide with that for the adjoining pixels within the LCOS display so as to avoid the fringe effect (bright lines).
