A micromirror capable of analog pulse width modulation, and method thereof. A capacitor ( 406 ) in each micromirror element stores a charge representative of one pixel of image data. A comparator ( 414 ) compares the image data signal stored on the capacitor ( 406 ) to a reference signal from a reference signal generator ( 416 ). Depending on the results of the comparison, the address electrodes ( 418 ) of the micromirror are biased to deflect the micromirror ( 412 ). As either the image data charge stored on the capacitor ( 406 ), or the reference voltage changes, the output of the comparator ( 414 ) changes to alter the position of the micromirror ( 412 ).
