Sony introduced its next-generation microLED display technology (direct-view LED as the company calls it), the high contrast Crystal LED C-series (ZRD-C12A/C15A) and the high brightness B-series (ZRD-B12A/B15A).

The new display modules offer two pixel pitch sizes (in both series), 1.26 mm and 1.56 mm and are equipped with Sony's "X1 for Crystal LED" image quality processor, which features Sony's signal processing technology and microLED control technology. Other features include high-quality and high-resolution upscaling, Sony's Motionflow technology for smooth and artifact-free pictures without motion blur, 22 bit Super Bit Mapping, 120 fps (HFR) and HDR.

MicroLED-Info and Perovskite-Info are happy to announce the 2021 edition of The Perovskite Handbook. This book is a comprehensive guide to perovskite materials, applications and industry, and it is now updated to January 2021 and lists recent developments and new companies, initiatives and research activities.

Perovskites are an exciting class of materials that feature a myriad of exciting properties. Perovskites are now entering the display market, with applications in quantum dots, LEDs, lasers and more.

Reading this book, you'll learn all about:

• Different perovskite materials, their properties and structure
• How perovskites can be made, tuned and used
• What kinds of applications perovskites are suitable for
• Perovskites Quantum Dots
• Perovskite solar cells, their merits and challenges
• Perovskites-based LEDs
• The state of the perovskite market, potential and future
  
  

Samsung Electronics is now accepting pre-orders for its upcoming 110-inch 4K MicroLED TV, in Korea.

Customers who pre-order the TV (the price is 170 million Won, or about $155,000) will get a special bundle (home cinema package, refrigerator package or a travel package to Jeju island) in addition to a 7-year warranty (this will likely to be extended to all customers). Shipment will begin in March 2021.

Samsung Electronics announced that it will introduce its latest products, technologies and visions for the future of the display in its upcoming 'First Look 2021' event that will take place on January 6th 2021.

The teaser image shows all kinds of displays, it is likely to be an interesting event. Samsung may unveil its 110" 4K MicroLED TV which it already announced earlier this month, and analysts expect also some mini-LED monitors. Samsung could also showcase new OLED displays, maybe the QD-OLED monitors that it is reportedly developing.

VueReal announced that its patented flipchip structure demonstrated higher yields and lower costs compared to standard vertical LED process.

The company says that flipchip processes are favored by display makers, due to the easy integration they offer. Most processes, however suffer from low yields and a complex process. VueReal's process has achieved yields higher than 99.9%, and with a more automated fabrication line can even achieve higher yields.

2020 is soon over - and many in the world are really happy about that and hope that 2021 will bring the COVID-19 pandemic to an end. The MicroLED industry still continues its fast pace of development, even through this catastrophic period.

Sony published a teaser video that says the company will unveil the "next breakthrough" in directview display technology" on January 6th. It is likely that Sony will release a new MicroLED display technology:

Sony was the the first company to introduce micro-LED large-area displays with its launch of the Crystal LED (also called Canvas LED, or CLEDIS) displays in 2016. The company introduced its displays to the residential market in September 2020.

During the 2020 Chongqing Micro-LED Industry Innovation Forum, Konka introduced the world's first MicroLED Watch, the APHAEA Watch. This groundbreaking product uses a 2-inch microLED display with a pixel pitch of 0.12 mm - which means the resolution is around 400x400. The MicroLED chips are 30 um in size.

It is not clear how close Konka is to commercialize this product - but in any case this is a great achievement and this is the world's first microLED wearable display shown in a real product. The display is produced on an LTPS backplane, it achieves a brightness of 1,500 nits and a color gamut of 147% DCI-P3. Konka says that battery life of this watch is up to 35 days.

A few days ago Samsung launched a new MicroLED TV, 110-inch 4K prefabricated (not tiled) display. Today Korean publication PulseNews revealed that the TV costs 170 million Won, or about $155,000. Preorders will start before the end of 2020 and the TVs will ship in Q1 2021.

This is a premium at-home TV display, that offers a "breathtaking visual experience" - but still this is an extremely high price that means Samsung will not be able to sell large numbers of its new TV.

France-based 3D GaN LED developer Aledia announced that it has produced its first nanowire microLED chips on 300 mm silicon wafers, at the CEA-Leti pilot line. Producing microLEDs on large wafers is more cost effective and will enable integration with smaller-node electronics.

Earlier this year Aledia announced that it plans to establish a 140 million euros LED production fab in Champagnier, near Grenoble in France. The company already raised 80 million Euros towards that goal. The new fab will use Veeco's 300 mm MOCVD systems.
