Electromechanical grating display system with spatially separated light beams

摘要

A display system, that includes a light source for providing illumination; a linear array of electromechanical grating devices of at least two individually operable devices receiving the illumination wherein a grating period is oriented at a predetermined angle with respect to an axis of the linear array wherein the angle is large enough to separate diffracted light beams prior to a lens system for projecting light onto a screen; an obstructing element for blocking a discrete number of diffracted light beams from reaching the screen; a scanning element for moving non-obstructed diffracted light beams on the screen; and a controller for providing a data stream to the individually operable devices.
