Patent ID: 8115704

Claim:
A method of driving an emissive display, the display comprising a plurality of pixels each addressable by a row electrode and a column electrode, the method comprising: driving a plurality of said column electrodes with a first set of column drive signals; and driving a first group of two or more of said row electrodes with a plurality of forward bias row drive signals, which is a first set of forward bias row drive signals to cause pixels in two or more rows of the display to emit light at the same time, at the same time as said column electrode driving with said column drive signals; then driving said plurality of column electrodes with a second set of column drive signals; and driving a second group of said two or more row electrodes with a second plurality of forward bias row drive signals, which is a set of forward bias row drive signals to cause a plurality of pixels in each of two or more rows of the display to emit light at the same time, at the same time as said column electrode driving with said second column drive signals, wherein said electrodes of said first group are selected based on correlation or expected correlation between rows of image data and said row electrodes of said second group are selected based on correlation or expected correlation between rows of image data, wherein said pixels are OLED pixels and selecting of said first and second column drive signals and said selecting of said row electrodes of said first and second groups is performed such that a desired luminescence of said OLED pixels driven by said row and column electrodes is obtained by a substantially linear sum of luminances determined by said first row and column drive signals and luminances determined by said second row and column drive signals and to thereby build up a luminescence profile of a said row over a plurality of row scan periods.
