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.

BOE shows new OLED technologies at SID Displayweek 2021

BOE demonstrates several new OLED technologies at SID Displayweek 2021. First up is a new rollable display. The new display is 8-inch in size, and it features a resolution of 2592x2176 and a bending radius of 4 mm. BOE says the new display passed over 200,000 sliding cycles.

Last year at Displayweek 2020, BOE demonstrated a 12-inch rollable OLED. It has since been working with LG Electronics on the company's rollable smartphone (which was since canceled as LG withdrew from the smartphone market) and with OPPO on a 7.4-inch sliding OLED phone.

Here is Tianma's CFOT rollable AMOLED display

In March 2021 Tianma unveiled a new OLED display technology, which it refers to as CFOT OLED - a polarizer-free OLED that adopts color-filters instead to remove reflections. The company demonstrated a 8.03" CFOT OLED prototype at SID Displayweek 2021:

Tianma says that a CFOT OLED enables a thinner design, improves the light emittance and also cuts the power consumption by 20%. The 8.03" display offers a resolution of 2000x2544 (403 PPI).

AUO shows world's largest OLED fingerprint sensor

AU Optronics is demonstrating its new under-the-OLED fingerprint sensor, which it says is the world's largest size sensor at 2.9-inch.

A larger sensor is useful as it makes it easier for the user to sign-in, and it also enables support for multi-fingerprint identification for biometrics security. The sensor features high-resolution (1,000 PPI) suitable for detection of small child fingerprints and also includes a heart-rate sensor for added security.

Visionox shows new OLED technologies at SID Displayweek 2021

Chinese OLED producer Visionox demonstrates several new OLED technologies at SID Displayweek 2021. We'll list some of these new achievements in this post, and you can see these in the video below.

Visionox shows a 'dynamic' 12.3-inch rollable display which feature a 5 mm rolling radius. A 7.92" foldable (2 mm radius) wrap-around display solution. Visionox also demonstrates a 12.3" three-folded OLED that can fold inwards (2.5 mm radius) or outwards (6.5 mm) - to become a 5.4-inch display.

LG Display develops a 3K 1.16" OLED microdisplay for VR applications

Last year at SID Displayweek 2020 LG Display unveiled a new OLED microdisplay, branded as OLEDoS. LGD's display was a 0.42" 1280x720 (3,500 PPI) panel that uses a color-filter based design.

This year at Displayweek 2021, LGD is showing the same display again, this time it reveals it has a brightness of over 5,000 nits (in 2020 the company said the brightness was "over 4,000 nits"). LG says that OLED microdisplays will find a market in VR and AR applications, as the displays outperform mobile AMOLED displays.

Nippon Shokubai demonstrate its latest OLED lighting panels

Japan-based Nippon Shokubai announced that its OLED lighting panels will be used in an upcoming textile exhibition in Japan. The company's fiber-type OLED lighting panels will be woven into a fabric, as can be seen in the video below:

Nippon Shokubai is developing OLED lighting panels under the iOLED brand. Its panels are very flexible and are only 0.07 mm thick. The company developed two panel types: a red panel which features a brightness of 5,000 cd/m2, EQE of 29% and >10,000 LT50 (@ 1,000 cd/m2) and a green panel that features a brightness of 7,000 cd/m2, EQE of 23% and >10,000 LT50 (@ 1,000 cd/m2) .

TCL shows a smartphone concept that includes a rollable and foldable OLED display

Chinese smartphone producer TCL unveiled an interesting new smartphone prototype (concept?) called the Fold ‘n’ Roll.

As you can see in the video, the device has a 6.87-inch OLED display when fully folded. It can open up (out-folding) into a 8.85-inch display, and then it can open even further to a 10-inch tablet-like device using a rolling mechanism. The display itself is produced by TCL's CSoT subsidiary.

Will Samsung Electronics start using LGD's OLED TV panels?

According to an interesting report from Korea, Samsung Electronics is discussing a potential supply agreement with LG Display for WOLED TV panels. Samsung is aiming, according to the report, to buy 1 million OLED TV panels in 2021, and 4 million (around 50% of LGD's capacity!) in 2022.

This development, if true, may have a major impact on the industry, and may spur LGD (and other OLED makers) to accelerate OLED TV production and capacity expansion plans.
