ABSTRACT:
A method of resetting the cells of a spatial light modulator (FIG. 11). A saturation voltage pulse is applied, causing the cells to achieve a fully saturated state in a given amount of time. A reset pulse of opposite polarization than the saturation voltage pulse is then applied, driving the cells toward the opposite fully saturated state. The reset pulse is removed after the same amount of time, causing the cells to assume their relaxed state in the same amount of time it took them to achieve their fully saturated state.
