Abstract:
1. A display system comprising: a) a micromirror array comprising a plurality of mirrors; b) a control function for controlling the mirrors to operated in a first modulation control state by driving the mirrors a first driving scheme and a second modulation control state by driving the mirrors by applying a second driving scheme to move the mirror with a different movement characteristic than the first driving scheme; and c) a switchover controller for controlling a switch from the first modulation control state by driving the mirrors with the first driving scheme to second modulation control state by driving the mirrors in the second driving scheme, or from the modulation control second state by driving the mirrors in the second driving scheme to the first modulation control state by driving the mirrors in the first driving scheme; wherein the switchover controller switches the state of mirrors at a predetermined point within a frame period.
