Abstract
A method for selectively applying a voltage to selected points on a surface is disclosed. The method utilizes a layer of photo-conductive material in contact with the surface in question. The layer of photo-conductive material is illuminated in the region immediately above the selected points so as to cause the voltage on an electrode bonded to one surface of the photo-conductive region to be electrically connected to the selected points.
