MICLEDI announces red GaN MicroLEDs
Red microLEDs set to emerge in the RGB trio for full-colour displays
MICLEDI Microdisplays, a developer of microLED displays for augmented reality (AR) glasses, has demonstrated 630nm wavelength red GaN with full-width-half-max (FWHM) in the range of 50nm.
Historically, red microLEDs have suffered a reputation as a poor performing part - this breakthrough by MICLEDI helps to put that reputation to rest. Red GaN Is compatible with MICLEDI’s proprietary CMOS-fab technology and follows the identical process recipe of the company’s blue and green arrays for consistency. It accommodates pixel-level micro lenses for high-efficiency optics integration and Is tailored for industry-standard 300mm commercial foundries for high-volume mass production.
Sean Lord, CEO, said: “AR headgear in the market today ranges from monochrome monocles for limited information-only displays to monochrome headsets and heads-up displays to full-colour glasses for industrial, enterprise and military applications. Prices range from $1000 to over $5000 per headset, which is too high for the average consumer. With the addition of red GaN to our tool kit, MICLEDI is perfectly positioned to bring the cost and volume advantages of its 300mm manufacturing flow to open the door to future generations of AR glasses that consumers can afford and enjoy.”
With this announcement, MICLEDI now has all three microLED colours coming into the market. The company continues its close affiliation with IMEC and other significant partners.
“Red GaN is but one option,” added Lord. “Alternative approaches vary from AlInGaP to Quantum Dot, and other techniques. MICLEDI is committed to pushing the cost, reliability, and performance envelope of each of these alternatives to provide the best in full colour microLED display modules across a broad range of performance parameters for transparent lens AR glasses.”
MICLEDI introduced its blue GaN and green GaN LED display test chips earlier this year. The new red samples are projected to be available to customers before the end of the year.
