Abstract:

The report describes the investigation into the problem of finding a polymer material to serve as the deformable medium for a light valve display device called the Deformographic Storage Display Tube DSDT. The DSDT operates on the principle of generating minute deformations in a deformable material by the establishment of an electrostatic force from charges deposited by a cathode ray beam. The deformations in the material are translated into a visual image by projection through a Schlieren optical system. The DSDT has demonstrated feasibility to be a multipurpose display tube. It exhibits storage, controlled persistence, selectable erase, high resolution, high dynamic range, and display sizes from 6 to 60 inches from a single tube.
