Abstract
A linear D.C. gas discharge display is provided wherein light emissions resulting from the application of video pulse trains to a linear array of preionized illuminable gas discharge cells comprising the display are used for selective point to point exposure and discharge of a uniformly electrostatically charged photoconductive insulator to thereby produce a latent electrostatic charge image for development. Various embodiments are disclosed for conditioning and addressing the array of illuminable gas discharge cells.
