Patent ID: 7580047

Claim:
A method for driving a display device, said method comprising: receiving a multibit data word indicative of an intensity value to be displayed on a pixel in a row of said display; defining a time period during which an electrical signal corresponding to said intensity value will be asserted on said pixel; dividing said time period into a plurality of time intervals, the number of time intervals depending on the number of bits in said multibit data word; initializing said electrical signal on said pixel at a first time during one of said time intervals selected from a first plurality of said time intervals depending on the value of at least one of the bits of said multibit data word; and terminating said electrical signal on said pixel at a second time during a subsequent one of said time intervals selected from a second plurality of said time intervals such that the duration from said first time to said second time during which said electrical signal is asserted on said pixel corresponds to said intensity value, said terminating of said electrical signal including updating the value of said electrical signal based on the value of at least one of the bits of said multibit data word during some, but not all, of said time intervals.
