EXALOS AG is developing visible RGB superluminescent light-emitting diodes (SLEds) as illumination sources for next-gen AR microdisplays. SLEDs exhibit performance characteristics that bridge the gap between semi-conductor lasers and LEDs. They combine the potential of wide-color gamut and high efficiency with high-spatial coherence (high directionality) and low-temporal coherence (reduced speckle content/coherent artifacts). Consequently, they offer important benefits when used to illuminate near-to-eye MEMs-scanning architectures and spatial-light modulators in holographic display systems.
At the I-Zone, EXALOS demonstrated its first prototype cyano-green (490-500 nm) SLED and its new red-blue devices. It also demonstrated reduced speckle in a projection application; showing the advantage of their special light source known as “super amazing diode,” a speckle-free laser.
Filmed at the I-Zone demo and prototype area at SID Display Week, the world's largest and best exhibition for electronic information display technology.
Display Week’s I-Zone, sponsored by E Ink, is a unique exhibition-within-the-exhibition filled with demos and prototypes from around the world. Every year, dozens of applicants submit their pre-market and emerging products to compete for a free booth where they can share their inventions with buyers, manufacturers, potential partners, industry leaders and thousands of attendees.
