Abstract
A method for causing a micromechanical spatial light modulator to display data for a period less than its settling time. The modulator elements receive a first pulse (40) that causes them to release from their previous state, a bias voltage is removed and reapplied, allowing the elements to move to the unaddressed state, and then the elements receive a second pulse (46). After receiving a second pulse, the elements assume an unaddressed state. In one embodiment, new address data is loaded during this unaddressed state, after which a bias is reapplied causing them to achieve the state corresponding to the new state. In another embodiment, the previous addresses are cleared during the unaddressed state, forcing the elements into an OFF state. In either embodiment, a reset pulse may be applied after either the load or clear step.
