Abstract
A method for using pulse-width modulation in displays. A series of PWM sequences is established. Each subsequent sequence clears the previous sequence before it, eliminating the need for a separate clearing reset at the end of the previous sequence. This allows for use of spoke bits in color-sequential systems. In non-color sequential systems and rapid color-switching systems it allows the sequence for one frame to flow directly into the sequence for the next frame.
