Abstract:
A system and method of providing a micromirror pixel 400 that is highly resistant to bright failure states. The micromirror 400 uses an asymmetric yoke 402 to ensure the mirror is only attracted to the address electrode in one rotation direction. The landing mechanism on the other side of the torsion binge axis also is altered to allow the pixel to over rotate in the “off” direction. The over rotation ensures that light reflected by the mirror when in the off direction will miss the projection lens pupil, allowing the corresponding pixel to remain dark in both an operational and failed state.
