Abstract

This invention provides a display control system that includes: a) a micromirror array (212) comprising a plurality of mirrors (212); b) a first control function (321) for controlling the mirrors in a first state; c) a second control function (322) for controlling the mirrors in a second state; d) and a switchover controller (323) for switching from the first state to second state, or from the second state to first state, wherein the switchover controller (323) switches the state of at least two mirrors simultaneously at a same predetermined point within a frame period.
