Abstract
A spatial light modulator driven with binary pulse-width-modulation requires very high data transfer rate to achieve high grayscale. This invention enables to reduce substantially the data transfer rate using non-sequential order of binary bits, wherein the combination of the sequences of binary bits is selected from the combinations which avoid simultaneous writing of multiple rows. The possible number of such combinations is astronomically large and mathematical programs were developed to find right combinations. These results were proposed.
