Field-updated deformable mirror device

Abstract

The bistable deformable mirror device circuitry 83 used in a high-definition television (HDTV) 82 application must be capable of supporting at least 128 grey levels, using pulse-width modulation. If the DMD is line-updated, then the minimum field time to support 128 grey level cannot be achieved because of the time required to perform a resonant reset once each line. This disclosure shows how the DMD can be field-updated in order to achieve the minimum required field time.
