KAUST researchers develops highly-efficient GaN and InGaN red microLED devices
Researchers from King Abdullah's University of Science & Technology (KAUST) in Saudi Arabia developed GaN and InGan red microLED devices that are highly efficient.
The researchers managed to increase the efficiency of their previous design by a new chemical treatment that removes damages at the microLED sidewalls (created during the fabrication process) and also retains the high crystal quality at the InGaN and GaN sidewall interfaces.
GE and Current Lighting Solutions to develop PFS/KFS phosphors for microLED applications
GE and Current Lighting Solutions have signed a collaboration agreement on small-size Potassium Fluorosilicate (PFS/KSF) phosphor for MiniLED and MicroLED applications. The two companies have a long-standing relationship in the world of PFS/KSF phosphor, and this new agreement extends their previous agreements.
The two companies will develop advanced versions of KSF Red Narrowband phosphor with material properties required to enable the use of these materials in advanced display technology such as emissive microLEDs. GE has the exclusive rights to license KSF technology for display applications and will work with display companies to license KSF technology into these advanced displays.
3D-Micromac launches a new microLED LIFT mass transfer tool
3D-Micromac announced a new microLED mass transfer tool, called microCETI. The company says its new technology can be used to transfer over 130 million microLEDs per hour.
MicroCETI is based on a laser-induced forward transfer (LIFT) process that can support almost any microLED material and shape. The tool also includes optional modules - a laser lift-off (LLO) module, and a single LED die repair module.
AU Optronics shows its microLED display prototypes at SID Displayweek 2021
AUO Optronics is showing its latest microLED ALED display prototypes at SID DisplayWeek 2021. Most of these aren't new display (AUO already demonstrated these last month) but it's the first time we got these on video:
You can see the 1.39" 472x472 (338 PPI) full-circle microLED display, developed together with PlayNitride. You can also see AUO's 12.1-inch 169PPI microLED display it first demonstrated in SID 2020, and the 9.4-inch 228 PIP flexible microLED prototype it also developed together with PlayNitride.
