Abstract:
1. Method of scanning lines in a display within a frame, where driving luminance information provided to the display for each pixel within the frame is divided into subfields, the method including the steps of: selecting subfields to be used when scanning lines in a set of scanning cycles equivalent to the number of subfields existing for driving the pixels, scanning the lines consecutively for the set of scanning cycles, and varying the selection of subfield from line to line in each scanning cycle such that the subfields are selected in a consecutive order from line to line as the lines are scanned consecutively, the subfields of two consecutive lines do not overlap with respect to time during each scanning cycle, no two consecutive line scans use the same subfield and no line is scanned using the same subfield twice during the set of scanning cycles, such that image flicker caused by the subfields is reduced.
