Abstract
In accordance with particular embodiments, a system for displaying modulated light includes a spatial light modulator comprising a plurality of micromirrors having a pixel pitch less than 17 micrometers. The system also includes an intermediate voltage generator operable to generate a negative voltage and a positive voltage. The system further includes at least two level shifters coupled to the intermediate voltage generator. The system additionally includes a reset driver coupled to the at least two level shifters and to at least a subset of the plurality of micromirrors. The reset driver is operable to drive the subset of the micromirrors. The spatial light modulator, the intermediate voltage generator, the at least two level shifters, and the reset driver are all incorporated on a common substrate.
