Abstract
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.
