Plessey signs a strategic partnership with Jasper Display to use Jasper's backplane on its GaN-on-Silicon wafers

UK-based GaN-on-Si MicroLED developer Plessey Semiconductor announced a strategic partnership with Taiwan's Taiwan's Jasper Display Corp (JDC). Under the new partnership, Plessey will use JDC's silicon backplane to drive its monolithic micro-LED displays produced on the company's proprietary GaN-on-Silicon (GaN-on-Si) wafers.

In May 2018 JDC demonstrated its latest JD27E2 8" wafer, and a 0.7" Full-HD monochrome (960x540 color) microLED microdisplay that is said to be the world's brightest at 100,000 nits (JDC later demonstrated a million nits micro display). JDC's backplane allows Plessey to fabricate highly efficient and ultra-bright micro-LEDs displays.

San'an Optoelectronics to set up its first micro-LED wafer production line in Q1 2019

San'an Optoelectronics logoAccording to Digitimes, China-based Sa'nan Optoelectronics is gearing up to setup its first micro-LED epitaxial wafer and chip production line in Q1 2019. San'an developed 20-micron micro-LEDs, and the company is now aiming to develop 4-micron LEDs and 10-micro LED flip-chips.

According to the report, San'an aims to start small-volume micro-LED production to be used for wearables, automotive taillights and large-area displays. The company's green and blue micro-LEDs are ready for commercialization, but its red chips still require development.

AUO demonstrates a 12.1" Micro-LED display prototype

At IFA 2018, AU Optronics demonstrated a 12.1" full-color TFT-driven micro-LED display prototype. The display features a resolution of 1920x720 (169 PPI). The micro-LED chips are less than 30 um in size.

The new AUO display uses blue LEDs with color conversion, which achieves "marvelous color performance", according to AUO. This is similar to the 8" 169 PPI display AUO demonstrated only three months ago at SID 2018.

LG unveils its 173" Micro-LED TV at IFA 2018

As promised, LG unveiled its first Micro-LED TV prototype at IFA 2018, you can see the gigantic 173" TV in the video below.

LG indeed said that its first Micro-LED TV will indeed be larger than Samsung's 146-inch modular Wall. But Samsung's design is modular, and also Samsung seems to be more advanced as it started accepting pre-orders in June 2018 and will soon ship its Micro-LED TVs for commercial applications.

Rohinni and Magna Electronics announce a new JV to develop flexible Micro-LED lighting panels for automotive applications

US-based Rohinni announced a new joint-venture with Magna Electronics to develop flexible mini-LED and micro-LED based lighting devices for the automotive market.

The new JV, controlled by Magna Electronics will be called Magna Rohinni Automotive Electronics and will be based in Holly, Michagan, US. In addition to the JV, Magna also made a minority equity investment in Rohinni.

Reports from Korea say that LG's first Micro-LED TV is on track for a September launch

In January 2018 Samsung unveiled its first Micro-LED TV, the 146-inch modular Wall, and started accepting pre-orders in June 2018. In February, Samsung's rival LG said that it is developing its own Micro-LED TV and it was rumored that it will unveil its first prototype in September 2018.

In a new report, the Korea Herald now claims that LG is indeed on track to reveal the first TV in September 2018 (at the IFA conference in Germany, which actually starts on August 31). LG's first TV will be larger than Samsung's demonstrated device at 175-inch. Samsung's TV however is modular, so it can be made larger. It is not clear whether LG's Micro-LED TV will have the same design.

AUO has been doing Micro-LED R&D for years, but the technology is not ready for mass production yet

In May 2018 AUO demonstrated its first micro-LED display - a 8" 1280x480 (169 PPI) display which AUO says it is the world's highest resolution full-color TFT micro-LED prototype ever demonstrated.

AUO did not publish any roadmaps to commercialize micro-LEDs. At the company's recent earning report, AUO disclosed that it does plan to use micro-LEDs in niche products in the future - but following years of R&D, micro-LEDs are still too expensive and are not ready for mass production yet.
