Abstract
A low power, paper white, direct-view display includes an array of hinged micromirrors that are deflected between two states, a first state in which the micromirror covers a portion of the background and a second state in which the micromirror uncovers the background. In one particular configuration, a stability mechanism is incorporated in the display so that the micromirrors switch between stable states and remain in those stable states unless and until an actuating force is applied to the micromirrors that is sufficient to overcome an actuation threshold. The mechanics of the hinge, stiction due to Van der Waals forces or a combination of both can be used to provide bistability. Bistability allows power to be removed from the display between updates but requires active actuation between both states. The drive electronics are similar to those used in multiplexed LCDs.
