Earlier this year Sony announced the world's first QD-OLED TV, the A95K. The TV is not shipping yet, but the first reviews are in - and the ones we have seen say that the display quality of Sony's new TV (and Samsung's new OLED panels) is superb.

A reporter from DigitalTrends, Caleb Denison, for example, spent some hours in front of an A95K, and says that the display is bright (the brightest he has seen in a consumer TV) and it offers the most accurate colors he ever saw. The colors are pure and "better than any OLED, and most QLED TVs, too".

Notion Systems, a leading solution provider for industrial inkjet systems, announced that it had successfully installed an n.jet display system at Taiwan's Industrial Technology Research Institute (ITRI). The n.jet display system was developed in collaboration with MBRAUN/Germany and includes a fully integrated inert glove box solution that combines compact design with minimized nitrogen consumption.

ITRI is now using the new n.jet display system to research and develop novel OLED and QLED technologies. ITRI has developed many OLED technologies over the years, and it is now looking to replace vapor deposition and vacuum coating with inkjet printing which could reduce the number of steps, increase material utilization and increase display quality.

In 2020 Samsung decided to use inkjet printers made by Korea's Semes, in its QD-OLED production lines. This created a major problem for Kateeva which hoped to win that account, which resulted in massive layoffs including some of its executives. These inkjet printers are used to deposit the QD layer in Samsung's QD-OLED panels.

According to new reports from Korea, Samsung has decided to change course, and rely on Kateeva's inkjet printers in its 2nd QD-OLED production line (the SDC 98.5-Gen Q-2). The reports suggests that the Semes printers do not perform as well as Samsung hopes, and these also cost more than Kateeva's printers (but Semes is affiliated with Samsung, which helped it to get the orders).

Sony announced its 2022 TV lineup, which includes three new OLED TV series, including the A95K, which is the world's first QD-OLED TV ever announced.

The Sony A95K Master XR TV will feature 55" or 65" 4K 120Hz QD-OLED panels (produced by SDC), Sony's XR cognitive processor, Acoustic Surface Audio, XR Triluminos Max and Google TV OS. It features HDR10, HLG and Dolby Vision.

Last year, Poland-based Ergis Group launched an OLED encapsulation film platform called Ergis noDiffusion®. The company is currently testing its film solutions at customer sites in Asia, the EU and the US, and it is now starting to expand the platform for the protection of quantum dot films (QD films) used in display and lighting applications.

These new films can be tuned to fit specific needs. Ergis can deploy its films on several substrate types, with varying film thickness, and the barrier properties can be tuned to be between 10^-6 to 10^-3. This means that custom films can be created to suit the specific sensitivity of the QDs for water vapor and to achieve specific product lifetime or other required properties.

In 2019 Samsung Display formally announced its decision to invest $10.85 billion in QD-OLED TV R&D and production lines. It was reported before that SDC is started to produce panel prototypes, and is on track to start mass production in Q3 2021.

In the past it was suggested that Samsung Electronics does not want to adopt QD-OLED in its TV line, but this SE finally made that decision to commit to QD-OLEDs. A new report in Korea now says that Samsung Electronics plans to release the first QD-OLED TVs in the first half of 2022.

BOE demonstrates several new OLED technologies at SID Displayweek 2021. First up is a new rollable display. The new display is 8-inch in size, and it features a resolution of 2592x2176 and a bending radius of 4 mm. BOE says the new display passed over 200,000 sliding cycles.

Last year at Displayweek 2020, BOE demonstrated a 12-inch rollable OLED. It has since been working with LG Electronics on the company's rollable smartphone (which was since canceled as LG withdrew from the smartphone market) and with OPPO on a 7.4-inch sliding OLED phone.

Samsung Electronics reported its financial results for Q1 2021. The company's revenues was 65.4 trillion Won (around $58.7 billion USD). Operating profit increased 4% from the past quarter to $8.4 billion, as Samsung enjoyed strong sales of phones and consumer electronics, which offset slower sales of displays and semiconductors.

The past quarter saw a fall in the revenues of Samsung's display business, due to weak seasonality of mobile products and a shortage of chips.Compared to Q1 2020, however, earnings improved due to increased adoption of OLED displays in smartphones.

In 2019 Samsung Display formally announced its decision to invest $10.85 billion in QD-OLED TV R&D and production lines. It was reported before that SDC is started to produce panel prototypes, and is on track to start mass production in Q3 2021.

According to a new report from Korea, SDC is set to begin producing full module prototypes in June this year. In addition SDC had to increase the brightness of its panels as TV makers said it is not enough for premium TV adoption. SDC will produce both TV and monitor prototypes, which it will send to potential customers (such as Samsung Electronics, Sony, and Chinese TV makers). When customers approve the prototypes, SDC will be ready for commercial production.

We are happy to announce a new Metalgrass knowledge hub, QuantumDots-Info.com. Our new site focuses on QuantumDots technologies for the display industry. QDs are already used in many displays, and it is likely that the future will bring us more types of QD Displays, including QDEL and QD-OLEDs.

QuantumDots-Info brings you daily news, commentary, resources and updates about QDs in the display industry. You can subscribe to our weekly QD display newsletter here - and if you have not done so already, be sure to also subscribe to the free monthly OLED newsletter!
