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 LDCs 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.

[ We claim:] [1.]1. A direct view display, comprising:a background; andan array of micromirrors that are adapted to be electrostatically actuated to switch between two states, an open state in which the micromirror covers a portion of the background corresponding to a pixel of the display and a closed state in which the micromirror substantially uncovers the portion of the background, wherein said background has a surface that reflects ambient light, and each micromirror has an interior surface that absorbs light and an exterior surface that reflects light, said micromirrors being configured in pairs that switch together so that, in said open state, their interior surfaces absorb ambient light and, in said closed state, their interior surfaces face each other to reduce the absorption of ambient light and their exterior surfaces are exposed to reflect ambient light to and from the background.
