One embodiment disclosed comprises a method for bipolar operation of a
light-modulating array. The method includes driving light-modulating
elements of the array in a first polarity, switching polarities from the
first polarity to a second polarity, driving the light-modulating elements
of the array in a second polarity, switching polarities from the second
polarity to the first polarity, and repeating the steps. Another
embodiment disclosed comprises an apparatus utilizing a light-modulating
array. The apparatus includes a first look-up table storing data for
operating elements the light-modulating array in a first polarity mode,
and a second look-up table storing data for operating the elements of the
light-modulating array in a second polarity mode. The apparatus also
includes a drive system for driving the elements of the light-modulating
array. The drive system is coupled to both the first and second look-up
tables.
