Patent ID: 8228356

Claim:
A method for driving a display device including an array of pixels arranged in a plurality of columns and a plurality of rows, said method comprising: defining a plurality of modulation periods during which electrical signals corresponding to particular intensity values will be asserted on said pixels in said rows of said array; dividing each of said plurality of modulation periods into a plurality of time intervals; associating each of said rows in said array with one of a plurality of sets of said rows; receiving a plurality of multi-bit data words each indicative of an intensity value to be displayed by a corresponding one of said pixels in said array, each bit of said multi-bit data words having a weighted value and the sum of the weighted values of said bits of each of said multi-bit data words being not equal to (2 y −1), where y is a positive integer; and updating the electrical signals asserted on said pixels in a plurality of said rows during each of said time intervals with a plurality of pixel control units; and wherein each of said plurality of pixel control units updates only the rows associated with a particular one of said sets of said rows during each of said time intervals.
