Abstract
This disclosure provides systems, methods and apparatus for modulating light to form an image on a display, as well as methods manufacturing such apparatus. The display apparatus includes shutters having asymmetric light obstructing portions extending out from opposing sides of a shutter aperture along an axis of motion of the shutter. Actuators move the shutters laterally along the axis of motion to move the shutter between fully closed, partially open, and fully open states to modulate light, thereby forming an image.
