Abstract

A thin low power, paper white, direct-view display includes an array of bistable micromirrors that are deflected between two stable states, a dark state in which the mirror covers a portion of the background and a white state in which the mirror uncovers the background. The drive electronics are similar to those used in multiplexed LCDs but are modified in order to drive the micromirrors to one of their two stable states. The micromirrors in the enabled row are attracted up or down with sufficient force to exceed the micromirrors' bistable threshold and deflect the micromirrors to their dark and white states, respectively. The attractive forces on the micromirrors in the remaining non-enabled rows are insufficient to exceed the micromirrors' bistable threshold so that the micromirrors remain in their current stable state.
