Abstract:
1. In a method of driving a passive matrix electroluminescent display having a plurality of addressable rows and a plurality of columns to which successive frames of video data are applied and which intersect said rows to form a plurality of sub-pixels which when grouped together into sets form a pixel, the improvement comprising simultaneously addressing successive pairs of said rows for selecting distinct sets of a fixed number of said sub-pixels forming said pixel from a superset of said sub-pixels surrounding said pixel for each of a set of at least three sub-frames within a frame of said video data, wherein each of said distinct sets contains at least one common sub-pixel and is centered at spatial coordinates measured along said rows and columns that are different from spatial coordinates defining the center of at least one other said distinct sets, and applying video data to each of said sets of sub-pixels in such a manner that the time average of the video data over said frame of video data is in accordance with a video image to be displayed for said frame.
