ABSTRACT:
Electrodes in an image display device are biased by a circuit composed of a first switch means for applying a first potential to one of at least two sets of alternate electrodes. The circuit also includes means for isolating each of the electrodes in a given set from the other electrodes in that set. A second switch means applies a second electrical potential to one electrode in the other set. Alternate embodiments of the present invention relate to multiplexing of the switching circuitry to reduce the number of components.
