Abstract
Interferometric modulators may include a movable layer including both permanently anchored and programmable hinges. Unactuated programmable hinges may exert little or no force on the movable layer. When actuated, programmable hinges may exert a mechanical force on the movable layer in a direction approximately opposite to the direction of force exerted by the permanently anchored hinges. By increasing a voltage between the programmable hinges and an electrode, a progressive number of programmable hinges may be engaged. The mechanical force exerted on the movable layer by these hinges may change the relative position of the movable layer within an IMOD device.
