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 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 n times the number of said rows in said array, n being an integer greater than zero;

    receiving a multi-bit data word indicative of said intensity value; 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.
