BOE has unveiled a new display, a 55" 4K quantum-dots panel, which it calls AMQLED (active-matrix Quantum Dot LED) display. This display uses electroluminescent QD technology - which is similar to OLEDs but with QD emitters. BOE says the display achieves a color gamut of up to 119% NTSC, and a contrast ratio of 1000000:1.

The reports claims that BOE launched this as a commercial product, but the details are not clear. This technology has been under development for many years, but it hasn't reached the performance required by commercial products, so this is a bit puzzling, hopefully we'll learn more soon.

According to UBI Research from Korea, Samsung Display has managed to improve its quantum dots nanorod LED (QNED) technology, and the company aims to start buying production equipment next year.

Apparently SDC's plan is to replace the fluorescent blue emitters in its QD-OLED TV production process, which will of course turn these TV panels into QD-QNED ones.

Najing Technology Corporation Ltd., the leading Chinese manufacturer of quantum dot materials uses the Notion n.jet display systems for QD displays and light emitting diodes development and pilot production.

The n.jet display series prints functional layers in various steps of display production and for various display technologies. This includes rigid, flexible, OLED, QLED and LCD displays. In addition to its unparalleled precision, the platform complies with highest demands on process environment and process stability.

DSCC updated its OLED material market forecasts, seeing a lower growth ahead. DSCC says the AMOLED stack material market will grow from $928 million in 2019 to $2.06 billion in 2024 in a CAGR of 17%. Only a couple of months ago DSCC estimated that the market in 2024 will reach $2.69 billion - and even these were reduced from earlier estimates due to COVID-19.

DSCC says that the main reason behind the reduction in its forecast is lower OLED TV capacity. The company now expects a slower ramp up at the Guangzhou fab, and LG's P-10 10.5-Gen fab is now removed from the forecast period.

Helio Display Materials, based in the UK, was spun-off from both Oxford and Cambridge University, to commercialize photoluminescent and electroluminescent perovskite-based materials for the display industry - with solutions for the OLED, LCD and Micro-LED markets.

Our sister site, Perovskite-Info, posted an interview with Helio's CEO, Simon B. Jones, discussing the company's technology and business.

OLED-Info and Perovskite-Info are happy to announce the 2020 edition of The Perovskite Handbook. This book is a comprehensive guide to perovskite materials, applications and industry, and it is now updated to January 2020 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
   

Update: It seems we were mistaken, this prototype is not a hybrid QD-OLED, but a 'regular' OLED. This is still an impressive development - a rollable inkjet-printed OLED display.

TCL and Juhua Printing demonstrated a 31" FHD inkjet-printed rollable hybrid QD-OLED TV prototype. The display uses an IGZO (Oxide-TFT) backplane and TCL says that it has an aperture ratio of over 50%, brightness of 200 nits and a 90% DCI-P3 color gamut.

TCL's hybrid display technology (which TCL calls H-QLED) uses a blue OLED emitter coupled with red and green QD emitters. All three emitter materials are combined and printed using ink-jet printing technology.

In October 2019 Samsung Display formally announced its decision to invest $10.85 billion in QD-OLED TV R&D and production lines. SDC was supposed to start the plan in 2019, but according to a report from China the Company is delaying its initial investment. Originally mass production was supposed to begin in Q1 2021, but this may happen later if the investment is delayed.

It seems as if equipment makers expected to receive orders for production equipment, but that did not happen. The report says that Samsung decided to make personnel changes and transfer in January 2020 and only after these changes will the company finalize its investment plan in the new OLED TV fab.

The government of the Guangzhou province in China announced that it aims to help its local display industry and have allocated large funds - up to 2 billion RMB (around $285 million USD) in subsidies per company. The goal is to help companies invest in production of emerging display technologies - including OLEDs, Micro-LEDs, QD-LEDs, 3D displays, e-paper displays, graphene enhanced display technologies and more.

The subsidies will be given to companies that start trial production, and when mass production begins.

Researchers from Samsung's Advanced Institute of Technology (SAIT) developed a new method to increase the efficiency and lifetime of self-emissive Cadmium-free quantum dots. The researchers used Indium Phosphide QDs in a new structure that prevents oxidation and energy leaks and also absorbs current faster.

The researchers say that the new structure enhancements increases the internal quantum efficiency to almost 100 (the EQE reached 21.4%) while increasing the lifetime to a million hours (at a high brightness of 100 cd/m²). The maximum brightness is 100,000 nits. This performance is comparable to Cadmium-based QDs.
