Abstract
A method and system for controlling a pixel of a display using pulse width modulation (PWM). A desired grayscale value for the pixel is processed to generate a binary encoding having a plurality of select bits encoding a select value, and a dither bit encoding a dither value, encoded by a scheme in which a first select value and a first dither value indicate a center-aligned pulse of a first width having a leading edge at a first temporal position, a second select value and the first dither value indicates a center-aligned pulse of a second width having a leading edge at a second temporal position, and the first select value and a second dither value indicate a center-aligned pulse of a second width having a leading edge at the first temporal position. The binary encoding is provided to the display for pulse width modulation of the pixel.
