The object of this research program was to perform continuing work on a solid-state matrix display capable of presenting two-dimensional video information. The work has been directed toward perfecting the techniques required to provide distributed control of a solid-state matrix display. The main emphasis has been on developing the necessary scanning and driving circuitry to demonstrate the overall goal of combining the best characteristics of electroluminescent phosphors with those of ferroelectric ceramics, thereby achieving a simple, reliable solid-state matrix display. The work included studies of scanning and driving circuitry, studies of panel design, studies of fabrication techniques, selection of electroluminescent cells for best match with ferroelectric transchargers, and the construction of a 1200-element model display to permit evaluation of the techniques that were developed. Ultimate performance goals included a geometric resolution of 10 elements per inch, a continuous dynamic brightness in excess of 15 ft-L, a zero ambient contrast ratio in excess of 20 to 1, a useful life of at least 1000 hours, capability for producing a gray scale by independently controlling the brightness of any display element, and a frame rate that allows continuity of motion without objectionable blurring or perceptible flicker.
