Abstract: In a flat-panel display device, the ON/OFF duty cycle of each picture element of the array of picture elements is modulated during a multi-frame display sequence according to attribute information of respective picture element data to be displayed. The timing of ON/OFF and OFF/ON state transitions (i.e., the modulations) of the picture elements are coordinated within predetermined neighborhoods throughout the array of picture elements such that the state transitions occur substantially uniformly in space and time within a display neighborhood during the multi-frame display sequence. Advantage is taken of the visual averaging property by causing state transitions to occur substantially uniformly in space and time within each neighborhood throughout the array of picture elements during a multi-frame display sequence.
