Abstract
Methods and devices for generating grayscale using digital pulse width modulation between optical states. Grayscale may be generated for each component color using multiple algorithm cycles per display field. Subsets of binary weighted bit values for data values of each component color may be split across algorithm cycles to reduce the number of data comparisons per color per display field. The total number of data comparisons per color per display field may be reduced by half or more.
