Abstract

This paper describes optics designed for the application of edge emitting LEDs (EELEDs) in retinal scanned displays (RSD). Directly modulated semiconductor light sources are scanned onto the retina to generate high-resolution displays. Red visible laser diodes produce high brightness monochrome scanned displays, or when combined with blue and green sources, generate full color displays. Green CW, room temperature visible laser diodes with any appreciable lifetime are currently unavailable for such applications. Blue and Green InGaN EELEDs have sufficient radiance and modulation speed for RSD applications, but lack the optical gain and stimulated emission required for laser diode optical power levels. Consequently, bright EELED-based displays require designs for maximizing the system optical collection efficiency. This paper describes anamorphic collection optics designed for optimizing the brightness and resolution of retinal-scanned microdisplay systems incorporating EELEDs. This design utilizes the laser-diode-like characteristics of EELEDs to maximize the collected useable optical power.
