Abstract : During the fourth quarter the performance and characteristics of current image storage panels were evaluated. Also, work was initiated on development of techniques for fabrication of large area panels on single substrates. The loss of stored images due to both frontal excitation of the panel by room light and optical feedback from the electroluminescent layer to the photoconductive layer was investigated and, to a great extent, eliminated. The voltage dependence of the panel's transfer characteristic was measured. Resolution measurements were made on a 12-inch, 50-line/inch image panel. Factors influencing the uniformity and speed of panel erasure were also studied. In the area of technique development for large area, single substrate panels, several approaches were investigated. One approach involved formation of the panel electrode structures on acrylic plastic coated with a transparent conducting film of tin oxide. The usefulness of cadmium oxide as a transparent conductor on plastic and glass substrates was also investigated. A dual conductor arrangement for electrode lines was devised and preliminary tests made. A new panel structure employing continuous electrodes instead of interdigitated electrodes was also studied.
