Abstract: The conductive member associated with the target assembly of a deformographic display system is affixed to one side of the deformable dielectric member of the target assembly. The opposite side of the deformable dielectric member is affixed to the relatively non-deformable dielectric member, which is part of the target assembly and which stores the electrostatic charge pattern containing the information to be displayed. The conductive member is deformable and compatibly deforms with the deformable dielectric member in response to the deformations of the latter. The deformations of the dielectric member in turn are produced by the forces of the electrostatic field which results between the conductive member and the electron charge pattern. By affixing the conductive member to the deformable dielectric member, the deformations occur substantially in the same or one direction, i.e., in a direction towards the non-deformable dielectric member.

Abstract: A display tube is provided in which a dielectric target is charged by an information modulated electron beam, and the resulting electrostatic field between the target and a conductive ground plane deforms a dielectric film. The film is located in a separate chamber of the tube at the side of the target opposite the electron beam generating equipment. The film deformations behave as point light valves, and a visible image of the information contained therein is provided by transmissive or reflective optical systems.
