OLED displays and lighting in Seoul - March 2019

In early March we conducted a 10 day trip to Seoul, to attend the OLED Korea 2019 conference (and visit some local display companies).

Visiting Seoul is a great chance to witness some beautiful OLED installations - LG Display has been deploying its OLED lighting and display solutions across town in businesses and tourist attractions. Retail stores of course were showing the latest smartphones by Samsung and LG - all of which adopt high end flexible AMOLED displays.

NTHU starts producing candlelight OLED lighting desk lamps

Excessive exposure to blue light has been linked to many health issues (including cancer, diabetes, heart disease, obesity and insomnia). Researchers from Taiwan's National Tsing-Hua University, led by Prof. J.H. Jou, have been advocates of candle-light OLED lighting for a long time, as part of their fight against the hazards of LEDs and white light. We recently posted on Prof. Jou's latest research on smartphone display risks and the benefits of OLED displays.

In 2015, Taiwan's PMOLED maker WiseChip Semiconductors licensed National Tsing-Hua University's blue-light free OLED lighting technology (called Candlelight OLEDs), with an aim to mass produce these OLEDs by the end of 2017. That project faced delays, however and now NTHU announced that following a collaboration with China's OLED lighting maker First-o-lite it is now ready to commercialize its technology and NTHU demonstrated the first device to use these new panels - the OLED lighting desk-lamp you can see in the video above (and photo below).

Yeolight new candle-like OLED lighting panels to soon hit the market

Yeolight Technology (which was spun-off Visionox in May 2015) developed candle-shaped transparent OLED lighting panels. The segmented panels have five different lighting panels each with its own brightness. The total size is 11.26 x 26.26 mm (with a thickness of 1.05 mm).

Yeolight tells us that these new OLED candles has been developed for a customer that will soon ship its final product to the market. The panels are now in production.

An Audi ad at Departures magazine includes flexible OLED lighting panels

Departures magazine (a premium magazine shipped to around 25,000 American Express Platinum Card members) included an innovative ad for Audi's A8 with flexible OLED lighting panels that are activated when first opened (and also when the reader clicks on a replica Audi key that is included with the magazine).

Personally this seems to be an overly expensive and wasteful way to advertise. We do not know what kind of OLED panels are used in the ads (which was produced by US-based Structural Graphics). In 2017 Konica Minolta Pioneer OLED (KMPO) demonstrated its simple flexible OLED lighting panels integrated into packaging technology - which could be the one adopted here (although other companies have demonstrated similar solutions as well).

Yonsei University deploys OLED lighting installations

Korea's Yonsei University deployed OLED lighting installations, one in its 24-hour study room (Laptop area) and the other in its Hall of Fame. The University says that the new OLED lighting systems provide better eye-comfort and upgrade the study atmosphere.

The Laptop Area uses rectangular OLED panels, both in the ceiling chandeliers and on the desks themselves. The Hall of Fame uses LGD's 300x300 mm flexible OLED panels.

The EU launches Lyteus, a €14 million initiative to support PI-SCALE OLED lighting projects

In 2016 the EU launched the PI-SCALE project, which established a European-wide roll-to-roll flexible OLED lighting pilot production line, with an aim to enable companies of all sizes to quickly and cost effectively test and scale up their flexible OLED lighting concepts.

Now the EU has launched a €14 million initiative within PI-SCALE called LYTEUS, which provides the expertise and capability required to progress an OLED lighting concept from an idea and into a commercialized product. Lyteus helps companies with sheet-to-sheet and roll-to-roll prototyping of flexible OLEDs, technology transfer, device encapsulation and more. At launch Lyteus serves four customers: Audi, Rehau, Emde and Pilkington, to develop flexible OLED lighting products in the automotive, aeronautics and designer luminaires sectors.

OLEDWorks announces new rigid and flexible OLED lighting panels

OLEDWorks announces two new OLED lighting panels, the rigid Lumiblade Brite 3 panels and the BendOLED flexible ones.

OLEDWorks Brite 3 OLED panels

The Brite 3 OLEDs are more efficient than OLEDWorks' current Brite 2 OLEDs, offering an efficiency of up to 85 lm/W. The brightness is 300 lumens (8,500 cd/m2) and the lifetime is 100,000 hours (L70, at 100 lumens). The Brite 3 OLEDs are available in two colors and offer a CRI of >90. The Brite 3 are offered in three product shapes: square, rectangle and round. These Lumiblade panels will be produced at OLEDWorks' Aachen production site.

We got a Konica Minolta Pioneer OLED's Christmas flexible OLED card

A few days ago we posted on Konica Minolta Pioneer OLED (KMPO) and its demonstration of simple flexible OLED lighting panels integrated into packaging. My friend Takatoshi Tsujimura, CTO at KMPO, sent me this nice Christmas greeting card, which arrived yesterday, with an integrated small red OLED. The OLED has a mirror finish when off.

This was exciting to get, and the whole card is very well done and feels great. It's a very nice surprise to see something light up in such a thin paper card. KMPO calls this concept "thin paper products with functionality".

Konica Minolta Pioneer OLED demonstrates flexible OLED lighting integrated with paper packaging

In June 2017 Konica Minolta and Pioneer established a new OLED Joint Venture called Konica Minolta Pioneer OLED, which will combine the OLED business and product divisions of both companies, with a focus on automotive applications.

KMPO released a new video today showing a different possible application of its OLED lighting - integration into paper for packaging or greeting cards. KMPO calls this concept "thin paper products with functionality".

New videos show the latest LG Display OLED installations in Korea and Hong Kong

LG Display published three very nice videos showcasing three new OLED lighting installations. First up is an OLED chandelier that was specifically designed for the presidential suite suite in the Landmark Mandarin Oriental Hotel in Hong Kong.

As you can see in the video above, the Chandelier has a unique design that uses 36 modules each with 4 OLED Panels (for a total of 144 10x10 cm panels). The project managers (TELCS Lighting Design and Consutancy) and the chandelier designer (Joyce Wang Studio) say that only OLED lighting panels provided them with the light quality and design possibilities that they wanted.
