<title>High-luminance active matrix electroluminescent (AMEL) display for see-through symbology applications</title>

Abstract

An Active Matrix Electroluminescent (AMEL) miniature display is reported with over l000fLluminance. This technology is demonstrated on a 0.7-inch diagonal 640x480 display. This achievement was made possible primarily through improvements in the AMEL design and process technology. Additionally, by addressing the display with only one bit of grayscale data, more ofthe frame time is available for applying light generating voltage pulses to the phosphor. This paper discusses the key characteristics of this display, including luminance, contrast, and power consumption. Details of luminance and grayscale tradeoffs are explained. System drive electronics used to interface this display to common video sources are also described.
