Abstract
A novel method for driving a display includes the steps of defining a modulation period during which a particular intensity value is asserted on a pixel of the display, dividing the modulation period into a plurality of coequal time intervals, receiving a data word, which includes a plurality of equally-weighted bits and is indicative of an intensity value to be displayed by the pixel, updating a signal asserted on the pixel during each of a plurality of consecutive time intervals during a first portion of the modulation period, and updating the signal asserted on the pixel every mtime interval during a second portion of the modulation period, where m is equal to the weight of each of the equally-weighted bits. The data word can either be composed of two groups of equally-weighed bits, or a combination of binary bits and equally-weighted. The invention also includes a novel display driver for executing the driving methods.
