Abstract:
1. A method of operating light modulating elements of electromechanical pixels wherein each said light modulating element takes a selective first or second position according to a set of selective address voltages, said method comprising the steps of: a) retaining said light modulating elements at said first and second positions by applying an electrostatic bias force to each said light modulating element; b) applying a new set of selective address voltages to said electromechanical pixels; c) displacing said light modulating elements from said first position to said second position by applying an electrostatic force to said light modulating elements; d) selectively displacing said light modulating elements from said second position to said first position by applying selective electrostatic force to each said light modulating element, and e) retaining said light modulating elements at the selected positions in step d) by reapplying said electrostatic bias force to each said light modulating element.
