China's largest display maker BOE Display has an active OLED ink-jet printing project, and according to reports the company is establishing an R&D production line (in Hefei) that uses Kateeva's inkjet deposition equipment.

At SID 2018, BOE demonstrated a printed OLED panel for the first time. Surprisingly this is a small mobile OLED display - a 5.5" FHD (400 PPI) flexible AMOLED. It is usually assumed that inkjet printing is limited to around 200 PPI, and so only useful to large area panels (such as TVs or monitors). JOLED's 21.6" 4K printed OLEDs have a PPI of 204, for example. In 2017 Korea-based Unijet's president said that Inkjet printing could reach up to 550 PPI in 2020 by using next-generation laser-droplet technologies.

China PMOLED and AMOLED producer Visionox demonstrated its first transparent OLED at SID Displayweek, a small transparent blue panel (60% transmittance).

The tag next to the display said this was a transparent AMOLED, but it is more likely that it was a PMOLED display - after all it was a simple monochrome blue one. In any case it is great to see Visionox developing transparent displays, in addition to the other next generation technologies it demonstrated at DisplayWeek.

Thermal activation sensitized fluorescence, or TASF, is a new type of TADF OLED emitter material developed at China's Tsinghua University. During SID Displayweek, Visionox demonstrated the first TASF prototype display.

We do not have a lot of information on this new emitter technology, except what Visionox provided at the conference: a sky-blue color (468 nm, CIE: 0.153, 0.201), a luminous efficiency of 26.6 cd/A and an external quantum efficiency of over 17%. The brightness of this OLED PMOLED display was 800 nits.

Samsung Display had a large booth at SID DisplayWeek, showcasing its latest OLED technologies (and also its QD-enhanced LCD TVs).

A large part of SDC's booth was dedicated to the company's automotive OLED technologies which included a wide range of flexible and rollable OLED displays - including flexible, transparent, rollable and a lightfield display.

Samsung Display unveiled new OLED technologies and displays at SID 2018 - including some new and enhanced VR AMOLED prototype panels.

The first panel on display was a 3.5" 1440x1600 (616 PPI) 90Hz display, and the second was a 3.2" 1824x1824 (806 PPI) 90Hz display.

LG Display showcased several of its OLED technologies at SID DisplayWeek. The most impressive display was a 77" panel that is both flexible and transparent. The large panel features a 4K (3840x2160) resolution and 40% transmittance. The bending radius of the display is 80 mm. This seems to be the same display announced in June 2017.

LGD also demonstrated, for the first time, its VR OLED display, developed in collaboration with Google. This is a 4.3" 3840x4800 (1443 PPI) glass-based display on an LTPS backplane, that supports a refresh rate of 120Hz.

The world's leading display conference, SID DisplayWeek, is now over, and it was a great event. This is just a quick first impression post - you can expect many more OLED-Info articles in the next couple of weeks after we get back to the office and sort through all the materials, interviews, photos and videos we have.

While LCD is still the dominant display technology in many applications, it is clear that OLEDs are taking over as the most promising technology, and we have seen exciting presentations and demonstrations from many companies. It was interesting to see how the three Chinese OLED makers at SID, BOE, Visionox and Tianma, have large booths with many flexible and foldable OLED displays and end products, while Samsung and LG Display both have very limited show areas compared to previous years. This is an interesting evidence to China's rising dominance - but also to Samsung's and LGD's focus on more consumer trade shows such as CES.

Visionox showcased it latest flexible OLEDs in a recent tradeshow, and Notebook Italia published this interesting video showing all of Visionox's displays.

Visionox is showing several interesting displays - a 5.99" 1080x2160 (403 PPI) AMOLED edge type flexible OLED, a full-screen 5.99" 2160×1440 flexible AMOLED and a 6.21" notch-type 2160×1440 AMOLED, with a touch sensor under the screen.

Today we are happy to publish this short Micro-LED explanation video, which we believe gives a nice introduction to Micro-LED display technology, production processes and to the current market status:

Researchers from Yonsei University managed to use a graphene-like 2D material called Molybdenum Disulfide (MoS₂) to create a transistor that can drive flexible OLED displays.

The researcher created a 6x6 OLED pixel array on a 7 mm plastic substrate that is so bendable (1 mm radius) it can be used as a skin sticker as can be seen in the video above.
