Plessey at Display Week 2019 showcases their proprietary monolithic microLED technology to enable a new generation of augmented reality devices simplifying optical systems that are brighter, smaller, lighter and higher performing than incumbent light sources currently used in AR/MR headsets, smart glasses, pico-projectors and HUD. Plessey’s GaN-on-Silicon is their route for monolithic addressable micro LED arrays/pixels for hi-res and hi-lum displays, high brightness LEDs, microLED displays, power devices, UV LEDs, photonic integration, advanced sensors, Plessey is creating compelling cutting edge display technology solutions, addressing the challenges and limitations faced in the field of photonics, arrays with emitters as small as 1 micron, driven at low current density for greater efficiency and longevity. External Quantum Efficiency at least three times higher than best in class benchmarks with more improvements in the pipeline. Arrays that provide at least 100,000 nits at 1 watt, that’s TV equivalent brightness at only 5mW, Coloured pixels fabricated in monolithic form. IP protected custom CMOS back plane provides rapid developments for custom arrays. GaN-on-Silicon MicroLEDs outperform incumbent technologies such as OLED with an outstanding thermal performance, Focussed light emitting surface, monolithic die/array Lm/W maintenance, excellent uniformity, integrated electronic and optical components, showcasing a 0.7-inch Micro LED display for AR, made by 8µm blue LED chips on JDC’s CMOS backplane to achieve a resolution of 1920*1080. Plessey upgraded its facilities and equipment recently, equipped with new semiconductor-level clean rooms and automated facilities, Plessey produces the world first wafer to wafer bonding Micro LED display with Micro LED epitaxy wafer and silicon CMOS backplane. As AR projection applications are targeted by several leading companies, Plessey has cooperated with technology partners including AIXTRON, JSC, Nanoco, VUZIX and others to enhance production facilities, demonstrating its capability of commercialization of Micro LED AR.

Gamma Scientific shows its Near Eye Display (GS-1290 NED) measurement system captures spectral measurements of Virtual Reality, Mixed Reality, Augmented Reality and Helmet mounted displays as viewed by the human eye. The telescopic optics are compact enough to fit inside a helmet and are designed to point in different directions to emulate the movement of the human eye.

Douglas Lanman, Director of Computational Imaging at Oculus Research, give his keynote address: “Reactive Displays: Unlocking Next-Generation VR/AR Visuals with Eye Tracking” at SID Display Week 2018, the world’s largest exhibition for electronic information display technology.

As personal viewing devices, head-mounted displays offer a unique means to rapidly deliver richer visual experiences than past direct-view displays occupying a shared environment. Viewing optics, display components, and sensing elements may all be tuned for a single user. It is the latter element that helps differentiate from the past, with individualized eye tracking playing an important role in unlocking higher resolutions, wider fields of view, and more comfortable visuals than past displays. This talk will explore the “reactive display” concept and how it may impact VR/AR devices in the coming years.

Douglas Lanman, Ph.D. is the director of computational imaging at Oculus Research, where he leads investigations into advanced display and imaging technologies. His prior research has focused on head-mounted displays, glasses-free 3D displays, light-field cameras, and active illumination for 3D reconstruction and interaction. He received a B.S. in applied physics with honors from Caltech in 2002 and M.S. and Ph.D. degrees in electrical engineering from Brown University in 2006 and 2010, respectively. He was a senior research scientist at NVIDIA Research from 2012 to 2014, a postdoctoral associate at the MIT Media Lab from 2010 to 2012, and an assistant research staff member at MIT Lincoln Laboratory from 2002 to 2005.

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.
