Abstract
A vacuum fluorescent printing device is disclosed having cathode filaments, a plurality of multiplexed control grids and a skewed matrix of addressable phosphor elements configured on an anode in such a fashion as to enable convenient electrical connection plus imagewise recombination of emitted light from said phosphor elements into a high resolution array for the purpose of directing this collection of addressable points of light onto a single line of a photoreceptor drum or belt thereby enabling a xerographic image to be generated. An equipotential screen grid is located between one of said plurality of grids and the anode in order to reduce voltage swings needed for cutoff of either grid for phosphor addressing purposes.
