According to a new report from Taiwan, EOSRL's new line, which will begin operation in Q3 2018, will be also used to produce small displays for VR applications. EOSRL reveals that the pilot line is already able to handle 2500 (50x50) chips per transfer, and by the time it is ready it will be able to handle 100,000 chips (100x100).

Taiwan's EOSRL aims to start large-area Micro-LED display production by the end of 2018

According to the patent description, the Micro-LED active area is aligned to an array of collimating reflectors that reflect a display image back towards a user's eyes. The patent also describes a similar VR device (in which the displays are not see-through).

Veeco and ALLOS demonstrate 200mm GaN-on-Si wafers for micro-LED production

Nov 02, 2017

Veeco and ALLOS Semiconductors have completed their micro-LED strategic initiative and demonstrated 200mm GaN-on-Si wafers for blue and green micro-LED production. Veeco transferred ALLOS' proprietary epitaxy technology onto Veeco's Propel Single-Wafer MOCVD System to enable micro-LED production on existing silicon production lines.

ALLOS says that it now has an MOCVD technology that is capable of high yielding GaN Epitaxy that meets all the requirements for processing micro-LED devices in 200 millimeter silicon production lines. Within one month the two companies managed to establish the ALLOS technology on Veeco's Propel systems and have achieved crack-free, meltback-free wafers with less than 30 micrometers bow, high crystal quality, superior thickness uniformity and wavelength uniformity of less than one nanometer.

Lumens aims to launch an automotive Micro-LED HUD by the end of 2017

Oct 11, 2017

Lumens logoThe Korean Herald posted an interesting interview with Jung Tae-hong, the president of Korea-based LED developer Lumens. Jung reveals that the company is developing an HD Micro-LED based automotive Heads-Up-Display (HUD), with lans to release its first such display by the end of 2017.

Lumens believes that Micro-LED displays are very suitable for HUDs as they can offer better usability under direct sunlight compared to LCD or OLED displays, and they can withstand high temperatures. In 2017 Lumens will launch a combiner-type HUD for the automotive aftermarket, and will introduce a built-in version within 2-3 years.

Samsung to accelerate its plans to develop Micro-LED based TVs

Oct 11, 2017

Samsung is reportedly starting to accelerate its effort to develop a Micro-LED based TV. The company is currently focused entirely on QD-LEDs for its premium TVs but is looking for alternative technologies as it fails to increase its market share in this segment.

PlayNitride MicroLED array

Samsung is said to be looking at several alternatives - one of which is to acquire Taiwan-based PlayNitride - a deal that was already reported in April 2017. Samsung aims to first use micro-LED technologies for its cinema LED screens, and then apply it to home-based TVs as well.

Digitimes: Micro-LEDs low aperture ratio makes them competitive for smart displays

Sep 28, 2017

Digitimes posted an interesting research note, in which they state that micro-LED displays may find it hard to compete with LCD and OLED displays as the market is approaching saturation.

Micro-LEDs have several advantages over other displays - high brightness, quick response time and the ability to create flexible and transparent displays (this is also true for OLEDs). However a major advantage for Micro LEDs is that the aperture ratio is only 10%, which means that there is a lot of empty space in a micro-LED display.

Taiwan's EOSRL to start producing 60-100 inch micro-LED displays in 2018

Sep 28, 2017

The Taiwan-based Electronic and Optoelectronic System Research Laboratories (EOSRL, part of Taiwan's ITRI) is developing 60-100 inch indoor micro-LED displays.

EOSRL is collaborating on this research with driver IC designer Macroblock. EOSRL is using LED chips that are 70-80 micrometers in size. EOSRL expects trial production to begin by Q4 2017, with mass production coming in 2018.

Mikro Mesa sees opportunities for large-area micro-LEDs with production line prices lower than at comparable LCD fabs

Sep 28, 2017

Taiwan-based Micro-LED developer Mikro Mesa's chariman, Chen Li-yi, estimates that it will be difficult for micro-LEDs to compete with OLED displays in the small/medium display market - but the opportunity for large area displays is more promising.

According to Chen, 55" micro-LED panels will be competitive in cost with LCDs, and if companies manage to achieve yields of over 80%, a 55-inch micro-LED will be cheaper by around 30% from an equivalent high-end LCD.

glō orders an MOCVD tool for Aixtron to deposit GaN nanowire-based Micro-LEDs

Sep 20, 2017

Swedish-American GaN nanowire based micro LEDs developer glō ordered an AIX G5+ MOCVD platform from Aixtron to support the company's strategic expansion. The tool will be delivered with a 8x150 mm configuration by the end of 2017.
