Samsung Display filed a complaint in the US that JOLED and Asustek infringe upon one of the company's patents, filed in 2017. The patent (USPTO # 9,768,240) details a TFT transistor array, and SDC says that both companies make use of the patent in the ProArt PQ22UC monitor.

In June 2020 JOLED announced that it has filed lawsuits in the US and Germany against Samsung Electronics and Samsung Display. JOLED says that Samsung infringed on its OLED patents without a license.

A couple of days ago, LG Electronics announced its first OLED monitor, the 31.5-inch 4K UltraFine OLED Pro, model 32EP950. Today JOLED announced that LG's monitor uses the company's printed OLED panels.

JOLED (Japan OLED) was established in August 2014 by Japan Display, Sony and Panasonic to produce OLED displays using inkjet printing technology. In December 2017 JOLED started commercial low-volume production of its 21.6" 4K OLED panels, at the company's pilot 4.5-Gen line.

OLED-Info and our sister site MicroLED-Info are happy to announce the 2021 edition of The MicroLED Handbook. This book is a comprehensive guide to MicroLED display technology, industry and market. MicroLED displays are thin, efficient, bright and flexible and are on track to revolutionize the display industry. The handbook is now updated to January 2021 and lists recent developments and new companies, initiatives and research activities.

Reading this book, you'll learn all about:

• MicroLED technology, materials and production processes

• MicroLED driving and full-color architectures
• The MicroLED displays currently on the market

In July 2020 LG Electronics announced that it aims to be the first company to introduce a rollable OLED smartphone - as early as the beginning of 2021. The company has now released a new teaser, showing the upcoming smartphone in action:

Unlike other rollable smartphone designs, LG's phone opens up on the wide size of the phone, to become an tablet form factor. LG did not give any information, specification or release date on what could be the world's first rollable phone.

TCL collaborated with perovskite QD film developer Zhijing Nanotech to produce 500 75-inch QD-enhanced LCD TVs with Zhijing's PQDF films. This is likely to be the world's first commercial adoption of pQD films in the display industry, as the TVs were sold successfully in China and Zhijing hopes to achieve a mass production design win with TCL in 2021

The company reports that the TVs featured a wide color gamut, 147% BT709 - which is higher than most QD TV's on the market, and higher than TCL's original 75M10 TVs. The green Cadmium-free pQD films have excellent optical properties and offer lower cost compared to current QD solutions, according to Zhijing Nanotech.

LG Electronics announced its OLED TV range for 2021, with three new OLED TV ranges. It seems the company is set to reveal more OLED TVs during the year, as some notes include model numbers that were not introduced yet.

But we'll start with the actual TVs. The company's mainstream TV range for 2021 will be the OLED C1. These 120Hz 4K TVs come in 48-inch, 55-inch, 65-inch, 77-inch and also 83-inch sizes., and feature LG's 4th generation a9 AI processor, the company's latest webOS v6 and supports HDR10, HLG, Dolby Vision IQ and Dolby Atmos. For gamers, the TVs offer HDMI 2.1, G-SYNC, FreSync, VRR and ALLM.

In October 2020 TCL's CSoT demonstrated some new rollable OLED technologies, and today at CES the company published this nice video you see below that again demonstrates new rollable OLEDs:

TCL first shows a rollable smartphone, that uses a 7.8-inch AMOLED that rolls into a 6.7-inch one. The display features a bending radius of 3 mm and CSoT says it can withstand up to 100,000 sliding cycles.

LG Display announced that it has developed and employed new OLED technologies, including new OLED materials and a new OLED device structure (with a new added layer) that enabled it to improve the efficiency of its large-area WOLED panels by around 20%. This enabled LGD to increase the brightness of its OLEDs.

The first display to adopt this new structure and materials is the company's 77-inch OLED panel, but LGD will also apply it to its other panels over 2021. LGD also announced that it will start producing 83-inch and 42-inch OLED TV panels, that will join its existing 48-, 55-, 65-, 77- and 88-inch models.

TCL has been involved with OLED inkjet printing technologies for many years, and the company''s chairman and founder Li Dongsheng yesterday posted that the company will reveal its first printed OLED products next week. Li also uploaded the following video that showcases the company's inkjet printing technology:

This is somewhat surprising as it may be too early for TCL to actually launch inkjet printed OLEDs. TCL has been a long time believer in inkjet printing for OLED displays, and the company has established Juhua Printing in 2016 (together with Tianma and other collaborators) as an "open-innovation platform" to develop ink-jet printing of OLED panels. Last year TCL invested $187 million USD in Japan's inkjet printing developer and producer JOLED, and has also signed an agreement to jointly develop OLED TV printing technologies.
