First-generation VGA electroluminescent display for head-mounted a

摘要

Abstract: The first VGA (640 $MUL 480) electroluminescent display is reported with a 24 micron pixel pitch and over 1000 lines per inch resolution. The display measures 0.71 inches by 0.53 inches and was designed specifically for head mounted applications. The display is fabricated on single crystal silicon-on-insulator wafers which allows the integration of the pixel as well as the peripheral addressing circuitry onto the display. Initial samples have been built utilizing both a green (ZnS:Tb), and an amber (ZnS:Mn) EL phosphor. Luminance, contrast ratio and power dissipation for displays operating at a 4.5 kHz drive frequency with a 60 Hz frame rate will be presented. Results indicate that this VGA display shows ideal characteristics for compact high performance head mounted applications. !7
