Abstract : A research and development program to design a reliable and inexpensive solid-state display control and logic circuit integrated with advanced electroluminescent displays capable of withstanding flight test evaluation is described. A basic system utilized a diode, resistor, electroluminescent cell integrated array. A control scheme incorporated an x, y switching arrangement with switches capable of operating at 800 volts peak at 400 hz. This array was backed up by integrated circuit logic and memory capabilities to provide a compact and efficient display package. Advanced techniques were employed in fabricating printed circuit boards and the multilayer assembly. A power change-over circuit was developed which permitted operation from 115 volts ac, 400 hz or 28 volts dc. A bar graph type electroluminescent panel, gapless display, was to be used with nine display packages and four numeric panels with five display blocks to make up the system along with a master control matrix.
