Abstract

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.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 102 words
In a deformographic display system of the type having a deformable solid dielectric first member means having a side in contacting relationship with an electrostatically chargeable nonconductive second member means and means for charging said second member means with a predetermined charge pattern, the improvement comprising: conductive compatibly deformable third member means in a predetermined contacting and joining relationship with an opposite side of said first member means, said first member means being deformed in a unidirectional manner whenever said second member means has an electron charge pattern stored thereon, and said third member means being likewise deformed in said unidirectional manner.
Claim 2
Dependent Claim 102 words
In a deformographic display system of the type having a deformable solid dielectric first member means having a side in contacting relationship with an electrostatically chargeable nonconductive second member means and means for charging said second member means with a predetermined charge pattern, the improvement comprising: conductive compatibly deformable third member means in a predetermined contacting and joining relationship with an opposite side of said first member means, said first member means being deformed in a unidirectional manner whenever said second member means has an electron charge pattern stored thereon, and said third member means being likewise deformed in said unidirectional manner.
Claim 3
Dependent Claim 16 words
