Abstract : A study program is described in which the feasibility of achieving levels of gray scale image storage in EL/PC image storage panels is studied. Both thick film EL and thin film EL lamp arrays were prepared and studied. Effort was concentrated on two techniques: slow decaying thin film photoconductors and multifrequency electrical driving of fast response EL/PC panels. The combination of materials used were prepared in test sample form, electrically and optically parameterized, and then computer simulations were performed to determine the range of parameters needed for a successful assembly. The computer models simulated the transient or steady state optical stimulation of EL/PC cells with simple sinusoidal power applied or more complicated waveforms. (Author)
