Abstract:
A method of operating a bistable micromirror array, said micromirror array comprised of at least one cell comprised of address circuitry and a deflectable mirror element, said method comprising the steps of:providing a data signal to said address circuitry in each said cell, said data signal representative of the desired integrated position of said deflectable mirror element; providing a ramp signal to said address circuitry in each said cell; generating a mirror address signal dependent on the difference between said data signal and said ramp signal, said mirror address signal having a first state when said difference exceeds a given threshold and a second state when said difference does not exceed said given threshold; providing a bias signal to said addressing circuitry, said bias signal operable to deflect said mirror element to a first position when said address signal is in said first state and a second position when said address signal is in said second state.
