DNP developed a new film to reduce blue shift in OLED panels

Dai Nippon Printing (DNP) announced that it has developed a new film that can help correct the blue tint problem that occurs in OLED panels when viewed from an angle.

The new film, which is marketed as "Blue Shift Control Film" is produced using a proprietary fine patterning technology that DNP developed. The company aims to supply this films to OLED producers and is planning to generate sales of around $23 million in annual sales from 2023.

Yeolight shows a new segmented OLED automotive taillight prototype, transparent segmented OLED display

China-based OLED lighting developer Yeolight Technology started developing automotive OLED lighting technologies back in 2017, and earlier this year it announced that the Hongqi H9 Sedan, which launched in China, uses the company's OLED taillights. At the 2020 Shanghai International Automobile Lighting Exhibition the company demonstrated a new OLED automotive taillight prototype, called E-Light:

The OLED lighting module, which is shaped like a triangle, uses 50 segments each a right-angled triangle with an area of 19 mm2. The segments are created by photolithography with an accuracy of <10 microns and can be controlled independently with 7 different brightness steps. The controller is a STMicroelectronics L99LDLH32 chip. The complete lighting module setup on display uses 9 such pieces for a total of 450 segments. The whole thickness of each module is 1.8 mm.

TCL's CSoT shows new rollable OLED display prototypes

TCL's CSoT demonstrated some interesting new displays at the DTC 2020 conference a few days ago - including rollable OLEDs, foldable OLEDs, ink-jet printed rollable OLEDs and new microLED prototypes.

In the video above, you can first see the company's latest inkjet-printed rollable OLED, with a size of 17-inch. CSoT says that it managed to reduce the OLED thickness by removing the color filters it used in earlier designs, which improves the flexibility - as you can see this display rolls up very nicely.

Konica Minolta's latest small flexible OLED lighting panels can be integrated with NFC

Last month we reported that Konica Minolta started to offer its flexible OLED lighting panels to global customers. One of the panels that KM is producing is a small red panel that can be integrated with an NFC antenna. This is an interesting concept, that is demonstrated in the video below.

The low power consumption of the OLED panel enables it to be powered by the NFC receiver and operate without a battery. It will be interesting to see what kind of applications will be developed using this technology.

Online review shows that the Galaxy Z Fold 2 is more durable than the original Fold, but not by much

When Samsung launched its original foldable smartphone, it used a polyimide-based cover, and the screen was fragile and not very durable. Later in 2020 Samsung Display launched its ultra-thin-glass (UTG) cover (produced by Schott and processed by Dowoo Insys) which the company said is more durable the the Polyimide.

Samsung Electronics continued to adopt the new foldable UTG cover and used it in its Samsung's Galaxy Z Fold2 5G (7.6" 1768x2208 HDR10+ 120Hz Dynamic AMOLED) smartphone. But the question remains - just how more durable is the UTG-protected OLED?

Konica Minolta's flexible OLED lighting panels now available globally

In March 2014 Konica Minolta announced that it is starting to construct a R2R flexible OLED lighting fab, hoping to start production in the fall of 2014. This fab entered production later than planned, and took a long time to reach real mass production capabilities. KM has been producing panels for quite some time, but finally it is offering its panels to global customers.

Konica Minolta is currently offering four different modules - two white panels, sized 43x15 mm and 15x15 mm and a red 15x15 mm panel. The red panel can be integrated with an NFC Antenna. The panels can be flexed (40mm radius) and they all offer a brightness of 500 nits.

LG's new teaser video shows the company's forthcoming rollable OLED smartphone

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.

LG seems to be progressing in this project, and the company released this teaser that shows what could be the next Explorer Project smartphone - and the one with the rollable OLED as the video shows a sliding-extending design.

The Hongqi H9 Sedan launches in China with OLED taillights made by Yeolight

China-based OLED lighting developer Yeolight Technology announced that its OLED panels were adopted by Hongqi in its latest H9 flagship sedan which is now being launched in the Chinese market. Hongqi is owned by FAW Car company and is actually the oldest Chinese passenger car brand.

The H9 uses 4 red OLED panels in each module. The panels are 131x32 mm in size and have 5 segments each. The color coordinate is CIY(0.69, 0.31).
