Abstract:
1. 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; associating each of said modulation periods with at least one of said rows; dividing each of said plurality of modulation periods into a plurality of time intervals; receiving a plurality of multi-bit data words each indicative of one of said intensity values to be asserted on said corresponding one of said pixels in said array; discarding at least one bit of each of said multi-bit data words prior to the end of said modulation period associated with said corresponding one of said pixels displaying said intensity value defined by said each multi-bit data word; and updating said electrical signals asserted on said pixels in an equal number of said rows during each of said time intervals based on any remaining bits of said multi-bit data words corresponding to said pixels such that each of said pixels displays said corresponding one of said intensity values; and wherein less than all of said rows in said array are updated during each of said plurality of time intervals.
