Abstract:
1. A display comprising a plurality of display elements, each of said display elements comprising: a movable reflector; a partial reflector positioned at a distance from the movable reflector thereby forming an optical resonator cavity, said movable reflector and said partial reflector separated by a gap; and a diffuser portion disposed forward the movable and partial reflectors, wherein said movable reflector is configured to move with respect to said partial reflector and to alter said optical resonator cavity in response to an electrical signal, and wherein (i) the plurality of display elements has a reflectivity at a viewing angle of about 45° that is greater than about 75% of the reflectivity of the plurality of display elements when viewed from normal and (ii) the diffuser portions are disposed sufficiently close to the partial reflectors such that the plurality of display elements achieve a contrast of greater than about 5 to 1 while using a displayed test pattern of alternating white and black lines of a spatial period of less than about 0.45 millimeter.
