Abstract
A method and system for controlling a color of light output by a diffractive light device (DLD device). The color is determined by a gap voltage applied to the DLD device. During each of a number of time frames, one of a number of control bits in a control word is sent to bit line logic corresponding to the DLD device. Each of the control bits represents a gap voltage level. The applied gap voltage is then adjusted to the gap voltage level represented by the one of the number of the control bits.
