China-based OLED producer Visionox has demonstrated several new OLED technologies at SID DisplayWeek 2019 last month, and the following great video shows the company's impressive booth and displays.

First up is a foldable OLED display that can be folded inwards and outwards. The panel's folding radius is 5 mm, and Visionox says that it can be folded over 200,000 times. The company did not disclose the exact size and resolution, though.

Taiwan's National Tsing-Hua University (NTHU) Professor Jou has been researching the hazards of blue light for many years, warning us against the hazards of modern lighting and focusing on OLED lighting as the technology that enables low blue-light emission lighting. In 2015, NTHU started to develop its low blue-light candle-light orange-type OLED technology, initially in collaboration with Wisechip and later with China-based OLED lighting producer First-o-lite.

NTHU has been promoting these candle-light OLEDs for the Smangus tribe in Taiwan's Jianshi Township which has been avoiding artificial light pollution. NTHU and the tribe managed to raise money to produce 240 OLED lamps, 90 for street lights and the rest to light up more than 100 cabins in the tribe's village. This is a beautiful project and hopefully will bring more attention to the hazards of blue light and the advantages of OLED lighting technologies.

BOE demonstrated a new AMOLED display that has a unique format - a 20:1 display (1209×63 mm) with a resolution of 3840×160 and relatively small bezels.

These kind of displays can be used for electronic shelf label applications - a field traditionally catered for by e-paper or E Ink displays due to their high efficiency and non volatility. E Ink displays are highly suited for these signage applications - but OLEDs can offer much higher image quality and colors so could suit some applications.

In January 2017 Novaled started constructing its new €30 million fab and office headquarters buildings in Dresden, a renovated old mill turned into a prestigious office building and state-of-the-art OLED R&D laboratories which increase the company's R&D OLED deposition capacity by 40%.

Novaled now officially inaugurated its new headquarters, and released the nice video above showing the new offices, facilities and laboratories - including the 110 meter long R&D center with fully equipped chemical laboratories and ISO5 and ISO7 cleanrooms. We wish all our good friends at Novaled the best of luck in the new location!

China-based CSoT demonstrated a foldable OLED prototype at SID DisplayWeek 2019, I believe this is the first time the company has shown a foldable display.

CSoT recently started pilot production at its 6-Gen LTPS flexible AMOLED production line in Wuhan and the company already achieved some design wins with "top-class" phone makers and is expected to start shipping OLED displays to its customers in Q4 2019. The Wuhan fab will have a monthly production capacity of 45,000 6-Gen substrates.

China-based BOE Display demonstrated many OLED displays at SID 2019, including new flexible, foldable, rollable and automotive AMOLED displays. Here's a video showing the company's complete SID lineup:

BOE also demonstrated its 55" ink-jet printed OLED TV prototypes and the company's latest OLED microdisplays.

In the last few years we witnessed an interesting evolution of smartphone display sizes: from bezel on the top and the bottom, to notch-type displays, to full-screen displays with pop-up selfie cameras and also displays with round laser-cut holes.

OLED makers have successfully integrated fingerprint sensors behind the OLED panels, but integrating a camera completely behind a transparent part of the OLED display is more difficult. Earlier this year Samsung Display estimated that it will take at least 3 years for this technology to reach the market - but yesterday both Xiaomi and Oppo unveiled smartphone prototypes with selfie cameras under the OLED display.

In November 2015 Planar launched its LookThru displays, based on 55" FHD transparent OLED panels made by Samsung Display. SDC stopped producing these OLEDs shortly after, though, and Planar had to halt its sales.

In February 2019 LG Display launched its own 55" FHD transparent OLED production, and now Planar announced its 2nd-Gen LookThru (LO552) displays - which are likely based on LGD's panels this time.

IGNIS Innovation published the following interesting video that shows how its compensation technology can remove the visible signs of pixel aging:

IGNIS tells us that this is a 12" LTPS automotive AMOLED panel. The company tested it for 1,000 hours at 85 degrees Celsius - to make sure the company's compensation technology can remove all signs of burn-in patterns. IGNIS's Max Life technology combines a functional in-pixel compensation pixel circuit with a sensing line and the company's current measurement driver chip that can perform external compensation.

Update: LGD confirms it is supplying the 13.3" foldable OLEDs to Lenovo's prototypes.

Lenovo demonstrated a prototype foldable ThinkPad laptop, that features a 13.3" foldable OLED display. Lenovo says that it developed this device for over three years, and hopes to launched a commercial one in 2020.

The reporters at The Verge really liked the device, but noted that the hardware is clearly not finished - the folding mechanism for example did not feel sturdy (and we all know this is critical in a foldable device) and the display itself suffers from "remarkably poor viewing angles".
