Abstract
A pixel is driven with pulse width modulation (PWM). A cycle for the PWM signal is divided into a plurality of super-intervals. Each of the super-intervals is divided into a plurality of intervals. An interval index is stored for the pixel. The timing at which the pixel is changed from one state to another is selected based on an enable signal and the stored interval index.
