Paper Abstract

Active matrix electroluminescent (AMEL) devices are fabricated using circuitry built on the thin-film single crystal silicon on insulator wafers. A 128 X 128 matrix with 24micrometers pixel pitch (1000 lines/inch) is fabricated with higher than 80% fill factor showing initial brightness of above 500fL and high contrast ratios (>100:1). These devices demonstrated the successful combination of active circuitry fabricated using conventional IC processing with standard electroluminescent processing. This AMEL approach provides the potential for head-mounted displays with a very small profile and high efficiency.
