Abstract
A method of pulse width modulating a spatial light modulator comprises determining a modulation sequence and applying the modulation sequence to the spatial light modulator in a time order method. The modulation sequence comprises a plurality of minor modulation segments. Each minor modulation segment comprises an always-on modulation segment in an always-on state. The plurality of minor modulation segments are temporally spaced such that the always-on modulation segments are spaced at predetermined intervals. Each minor modulation segment comprises at least one thermometer bit.
