NTHU develops an efficient and long lasting bluelight-free tandem OLED device

Taiwan's National Tsing-Hua University (NTHU) Professor Jou and Dr. Wen have been developing OLED lighting technologies for many years, focusing on healthy bluelight-free OLEDs (so-called candle-light OLEDs) due to the hazards of modern lighting.

The researchers now report they have developed a new tandem-OLED device that improves the efficiency and lifetime of their candle-light OLEDs. The OLED's emission is totally blue-light free, which makes it even safer compared to NTHU's first-gen candle-light OLEDs.

LG gets ready to ship its 31.5" 4K printed-OLED monitor, and the first review is in

LG announced its first OLED monitor, the 4K 31.5" UltraFine OLED Pro (32EP950) back in January 2021. The monitor should start shipping by the end of July 2021 for $3,999 - and now the first review is in, by BH Photo.

The reviewer says that this new display is "astonishing" and "immersive" - but admittingly there are some trade offs (compared to other top-end monitors): lower peak brightness, non-variable refresh rate, connector choices, etc. The review says that the 32EP950 is "truly made for professionals" and will be a best fit for graphic design, image and video editing, and broadcast grading. This is not a general-use monitor, especially at that price tag.

Yeolight shows new automotive OLED taillight prototypes, based on flexible and triangular panels

China-based OLED lighting developer Yeolight Technology published two new videos that demonstrate the company's latest OLED technologies. You can see the company's segmented triangular based modules, and also a module based on flexible red panels:

The triangular-based OLED, which the company refers to as digital OLED taillight (it reminds us of Audi's technology, produced by OLEDWorks, which goes by the same name), uses modules that use 50 segments (each a right-angled triangle with an area of 19 mm2). We do not have any information on the flexible panels.

OLED lighting may benefit your sleep, and even help reduce weight

Researchers from the University of Tsukuba in Japan have compared the effects of LED and OLED lighting on physical processes that occur during sleep. The researchers show that OLED exposure has a reduced effect on sleep architecture and energy metabolism.

OLED devices emits white light which contains less blue light compared to LED devices, and this does not lead to any effect on sleep architecture, but it does reduce energy expenditure and core body temperature. In addition, fat oxidation during sleep was significantly lower after exposure to LED compared with OLED. Thus OLED lighting has a similar effect to that of dim light.

OLED-Info overhauls its Automotive OLED Market Report

In early July, we published our quarterly update for our Automotive OLED Market Report. The update this time was comprehensive, as we overhauled the complete report.

The OLED Automotive market is heating up. AMOLED displays (mostly flexible ones) are finally being adopted by commercial cars, while OLED lighting panels continue to be designed into high-end automotive taillights as the ultimate lighting solution.
