Patent ID: 8237756

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 modulation period during which an electrical signal corresponding to a particular intensity value will be asserted on a pixel in a row of said array; dividing said modulation period into a plurality of time intervals, the number of said time intervals equal to the number of said rows to which data is to be written in said array divided by (m); receiving a multi-bit data word indicative of said intensity value, each bit of said multi-bit data word having a weighted value and the sum of the weighted values of said bits not being equal to (2 y −1), where y is a positive integer; and updating said electrical signal asserted on said pixel during at least some of said time intervals in said modulation period such that said intensity value is displayed by said pixel; and wherein (m) is an integer greater than one and a divisor of the number of said rows to which data is to be written in said array that leaves no remainder.
