MICLEDI presenting 300mm micro-LED array technology for AR glasses at Display Week
MICLEDI Microdisplays B.V. of Leuven, Belgium – a fabless developer of micro-LED display modules for augmented reality (AR) glasses – is demonstrating its technology at the Display Week 2022 event hosted by the Society for Information Display (SID) in San Jose, CA, USA (8-13 May).
As creators of what are claimed to be the first micro-LED arrays-for-AR built on a 300mm CMOS manufacturing platform, MICLEDI says that it enables more compact, power-efficient devices that address the needs of future AR glasses in terms of display size, resolution, brightness, image quality, power consumption and cost.
AR headsets are currently heavy, bulky and costly, and deliver poor image realism and low resolution. Nearly every leading technology company is investing in AR to drive the future of their consumer offerings, and micro-LED displays are a mission-critical component. MICLEDI says that its technology and manufacturing process overcome the challenges with first- and second-generation AR glasses to achieve the features that consumers will require for visually immersive AR.
At Display Week in Session 57 on 12 May (3:10-4:30pm in room 220C), MICLEDI’s chief technology officer Dr Soeren Steudel is giving a presentation ‘MicroLED Display Integration on 300mm Advanced CMOS Platform’ highlighting the reality and manufacturability of MICLEDI’s proprietary 300mm manufacturing flow.
Having first demonstrated its blue FHD arrays at the Consumer Electronics Show (CES 2022) in January, MICLEDI recently released ‘passive matrix’ samples of its next-generation blue arrays. These are manufactured in the firm’s proprietary 300mm reconstitution and hybrid wafer-to-wafer bonding flow, including a base CMOS metallization wafer, enabling customers to illuminate and characterize different portions of the array. By mid-2022, the firm expects to release samples of its blue array with its proprietary pixel-by-pixel lensing system designed to narrow the apex angle of each pixel for maximum brightness. Samples of green and red arrays are expected in second-half 2022.
“In just the last few months, we have made significant progress toward commercial readiness, as evidenced by the number of enthusiastic inquiries from, and ongoing conversations with, a wide range of tier-1 OEM manufacturers with special interest in the AR space,” says CEO Sean Lord. “Display Week is a premier opportunity for us to showcase our world-class 300mm micro-LEDs, discuss with customers our new high-volume, low-cost manufacturing partner GlobalFoundries, and engage our customers for next-generation samples coming throughout the balance of 2022.”
At Display Week, demonstrations are being given in MICLEDI’s booth #740 on the show floor at the McEnery Convention Center (10-12 May) and include samples of red, green and blue micro-LED arrays that can be examined with low- and high-resolution microscopes, as well as reconstituted gallium nitride (GaN) on silicon wafers, and diced devices.
