With Micro-LED moving from Engineering to Production, a near-zero tolerance for bad pixel, ultra-small pitch probing, automatic electrical and optical measurement systems need to step up. With STArâs enhanced Unicorn-LAIT II addresses these stricter testing requirements and with its unique parallel test architecture for electrical, driver functionality, RGB, optical testing capabilities.
STAr Unicorn-LAIT II Advanced Integrated Test System
Unicorn-LAIT II is an advanced high throughput LED test system, that caters for dies in hundreds of thousands to millions of LED per wafer. High Parallelization allows the customer to significantly reduce the Cost of Test and Test Time. The system provides critical measurements for Mini/Micro-LEDs and integrates parallel testing with the electrical, optical measurement with probe station and probe cards in one system, offering a comprehensive analysis result to industry users.
Porous-GaN material platform developer Porotech is demonstrating its latest microLED display prototypes at Touch Taiwan 2022. The company is showing 1920x1080 monochrome microidsplays, that achieve over 2 million nits of brightness. All displays use native indium gallium nitride (InGaN)-based LEDs.
The company says it is the first to demonstrate all three-color light emitting elements made from a single material and toolchain. This include Porotech's native red InGaN display at 614-625nm wavelength.
Taiwan-based microLED developer PlayNitride has demonstrated several new displays at Touch Taiwan 2022, with a focus on commercial and automotive display applications.
PlayNitride showed a new 9.38" transparent microLED (65% transparency), a 11.6" 2.5K automotive display, and also a 1.56" microLED that can be used for automotive use and also for wearable devices.
AU Optronics announced that it will showcase new MicroLED display prototypes next week at Touch Taiwan 2022.
AUO will show a rollable 14.6" microLED display, that offers a 2K resolution (202 PPI) with a 40 mm rolling radius. The company will also show a 17.3" 2000-nits 1280x720 transparent (60% transparency) microLED prototype. In 2021 the company demonstrated a smaller transparent display, which was even brighter at 3,000 nits.
MicroLED developer VueReal announced that it has raised $14.4 million in its latest (series B) funding round, led by Cycle Capital VC and joined by TDK, Vitro, Economic Development Canada and BDC Capital. VueReal says it will use the funds to enhance its production facility, expand the team, and gain new customers.
VueReal says that the new financing round will also enable it to offer a broader range of custom display products, for AR, smartwatches, smartphones, automotive, signage and transparent displays. Last year VueReal demonstrated high-brightness and high-transmittance transparent microLED displays which it is now offering to customers.
China-based GaN epiwafer producer Enkris Semiconductor launched new microLED epiwafers. The "Full Color GaN" series offers GaN-on-Si microLED epiwafers, with wafers sizes of up to 300 mm.
Enkris' new epiwafers offers blue, red and green LED arrays, all based on the same material platform. Enkris Semiconductor uses its patented strain engineering and polarization engineering, which it says is unique, to expand its GaN-on-Si LED epiwafer product portfolio to all colors (with wavelengths of 390-650nm).
ams Osram announced that it will expand its LED production plant in Kulim, Malaysia, with an investment of around $850 million.
The new fab will produce LED chips and microLED chips, on 8-inch wafers. ams Osram regards microLED as one of its key initiatives, but also sees the market a few years away.
Researchers from the National Yang Ming Chiao Tung University (NYCU) in Taiwan have found that by applying ALD Al2O3 passivation, it is possible to increase the external quantum efficiency of microLED chips.
The EQE of 5x5 um microLEDs was enhanced by 70%, and the EQE of 10x10 um chips was enhanced by 60%. The ALD passivation technology was also successfully used for the patterning of color-conversion QDs by inkjet printing (the passivation is used to prevent the quantum dots from photo-oxidation and degradation).
AR developer Mojo Vision announced that it has developed a new prototype of its innovative Mojo Lens display system, which is an AR-powered contact lens based display.
The display part of this system is still based on a 14,000 PPI monochrome (green) microLED microdisplay, which is less than 0.5 mm in diameter.
