Samsung aims to release a premium Micro-LED consumer TV in 2019

Samsung Electronics video and display chief, Han Jong-hee, says that Samsung aims to release a Micro-LED consumer TV next year. The TV will be a high-end premium set that will be called the Wall Luxury - and will not be priced as high as people think.

It's not clear whether this consumer version of The Wall professional will be modular. Han did say that it will be thinner than the current version at only 30 mm thick (the Wall Professional is 80 mm thick). This is still quite thick compared to current OLED TVs.

n-Tech sees a very bright future for Micro-LED displays, starting in 2019

n-tech Research says that the Micro-LED market will emerge in 2019, with sales reaching $2.7 billion. The market will grow very quickly to reach over $70 billion in 2027.

n-Tech says that the immediate markets for Micro-LED displays will be near-eye displays (AR/VR), automotive HUDs and projectors - as these will benefit mostly from the small size, low weight, high brightness and high resolution of Micro-LED displays. Wearables (smartwatches) is another lucrative market (n-Tech sees $1.6 billion in smartwatch Micro-LED display sales in 2022).

Yole: LCoS, DLP and MicroLED displays to dominate the AR market

Yole Developpement says that there are still several challenges to solve before AR systems that are good enough for mass usage are developed. Yole sees the market finally emerging in 2022 or 2023.

Yole sees three display technologies dominating this market - DLP, LCoS and MicroLED displays. OLEDs are very promising for this market as of today, but by the time AR systems are mass produced (2022/2023) MicroLED displays will prove better than OLEDs.

Aledia selected Veeco's GaN MOCVD system for large-area silicon R&D

France-based 3D GaN LED developer Aledia has selected Veeco Instruments’s Propel GaN metal-organic chemical vapor deposition (MOCVD) system to support its advanced R&D. Aledia aims to scale up its technology for large-area silicon using Veeco's system.

Veeco's Propel system will enable Aledia to process 6- and 8-in. wafers or 2- to 4-in. wafers in a minibatch mode. Aledia already uses Veeco's K465i MOCVD system.

Nichia: we're developing Micro-LED technologies, but it will take at least 4 years for Micro-LED displays to reach the market

Japanese-based LED maker Nichia says that the company has been developing Micro-LED technologies for several years, and the company can produce micro-LED chips - but the company estimates that it will take at least four years for Micro-LED displays to reach real commercialization.

Nichia is not only developing Micro-LED chips, the company also develops transfer technology and related equipment.

JBD unveils a 1 million nits MicroLED microdisplay

Shanghai-based Micro-LED microdisplay developer JBD demonstrated its latest Microdisplay that achieve an extremely high brightness - 1 million nits. The display resolution is VGA. JBD is already offering its monochrome VGA micro-LED microdisplays commercially (but we're not sure if these are the 1 million nits ones).

JBD's current micro-LED process still suffers from low yields, but the company hopes to achieve at least a 70% yield in the future, which will enable it to bring prices down to about $10 to $20 per display.

ITRI is developing new Micro-LED displays for small-size and large-size applications

Digitimes reports that Taiwan's ITRI institute is developing new micro LED displays for both small-size and large-size application.

For small-size displays, ITRI is developing a 0.55-inch micro-LED microdisplays (on-silicon). This display is aimed for AR or VR devices. For this display ITRI uses 10-micron LEDs. For larger-sized application, ITRI is focused on displays over 130-inch in size. For such displays ITRI adopts 50-100 micron LEDs on PCB substrates.

Samsung officially launches its The Wall Professional Micro-LED TV, starts to accept pre-orders in the US

In January 2018 Samsung unveiled its first Micro-LED TV, the 146-inch modular Wall, and later the company said it will start shipping it in August 2018. Yesterday Samsung officially launched "The Wall Professional" in a tradeshow in the US, and it is now accepting pre-orders, aiming to find customers in lobbies, museums, galleries, and retail spaces.

Samsung did not reveal the price of its new TV - but maybe that's because it is a modular premium commercial display - so each order will be handled differently. It is estimated that the price of the 146" model will be at least $100,000. The Wall Professional features HDR 10+ and its brightness is up to 1,600 nits.

Coherent nicely summarizes the differences between LCDs, OLEDs and Micro-LED displays

During a presentation at SID Displayweek 2018, laser developer Coherent showed a nice chart that summarizes the performance difference between LCDs, OLEDs and Micro-LED displays.

Coherent says that its lasers could be used in the pick-and-place process when making micro-LEDs. A laser lift-off process (LLO) removes the LED chips from the sapphire growth wafer (or any other carrier wafer) and a the laser-inducted forward-transfer (LIFT) process transfer selected dies from carrier to substrate in a high-precision way that can be massively parallel (over 25,000 dies per shot).
