ABSTRACT:
A method, device and system for utilizing a pixelized ungated linear array of field emitters and an integrated electrode-media surface to either detect the presence of charge on the surface in a given two-dimensional pattern, or to deposit charge on the surface in a desired two-dimensional pattern. The methods, devices and systems disclosed are particularly useful in the arts of printing, scanning and copying. In one embodiment designed for printing, a pixelized surface may be utilized to receive a charge pattern from the ungated linear field emitter array. In one embodiment designed for scanning, a pixelized transfer sheet may be utilized to transfer a two-dimensional charge pattern from a photostatic surface thereto for sensing and detection by the ungated linear field emitter array.
