Samsung Display announced a new OLED technology, called Adaptive Frequency that enables variable refresh rate in AMOLED displays - ranging from 10Hz to 120Hz. Running OLEDs at low refresh rates when possible can reduce the power consumption of the display (over all applications) by up to 22%.

This new display technology was applied for the first time in the Galaxy Note20 Ultra 5G smartphone, announced earlier this month, with its 6.9-inch 1440x3088 Dynamic AMOLED.

Xiaomi announced what could be the world's first mass-produced transparent TV for the consumer market, the Xiaomi Mi TV LUX Transparent Edition that features a 55" 120Hz WOLED TV panel.

The Mi TV LUX uses Xiaomi's AI Master Smart Engine built around a MediaTek 9650 TV chip, and has support for Dloby Atmos. The Mi TV Lux will start shipping on August 16 in China for 49,999 yuan (around $7,200).

OLED-Info is proud to announce an important update to our OLED Microdisplay market report, which now adds a microLED microdisplay section. MicroLED technology shows great promise to enable extremely high-brightness and high-efficiency displays, but there are still challenges to overcome. The report now include details on all microLED microdisplay developers and includes more datasheets and product information - for both OLED and MicroLED microdisplays.

This market report provides a great introduction to both OLED and MicroLED microdisplays, and covers everything you need to know about next-generation microdisplays. This is a great guide if you're considering to adopt microdisplays in your product and if you want to understand this industry better.

At SID Displayweek 2020, BOE demonstrated an OLED automotive taillight module, developed in collaboration with "automotive makers" which BOE did not detail.

The red OLED taillights from BOE offer up to 2,000 nits in brightness and a lifetime of over 20,000 hours. The panels are less than 0.3 mm thick and will operate in a wide temperature range (-40 to 95 Celsius).

During SID Displayweek 2020, BOE demonstrated its 12.3" Full-HD rollable OLED prototype screen:

BOE now details that the display has a rolling radius of 5 mm, and it can roll 4 cycles. BOE says that device can survive over 100,000 bending cycles.

Organic-TFT backplane/emitter developer Mattrix Technologies (previously nVerPix) announced that it has received a $1.5 million investment from JSR Corporation. This second investment by JSR is the first tranche in the company's new round (which will total, hopefully, $3 million)

JSR is a strategic investor, and has also launched a joint-development project for the development of solution-based conductive inks that will be sued in Mattrix's next-generation backplane transistors.

Researchers from Semiconductor Energy Laboratory (SEL) developed flexible OLED displays that incorporate organic image sensors inside the OLED pixels using side-by-side patterning. The sensors can be used as cameras for applications such as fingerprint sensing - which will work on the entire display.

SEL presented two prototypes, one a 3.07" 360x540 (212 PPI) display and the second is a 8" one with a higher pixel density of 302 PPI. SEL says that the fingerprint recognition works even when the display is bent.

China-based OLED producer Visionox demonstrated some of its latest OLED technologies at SID Displayweek 2020.

In the video above you can see the company's latest foldable, wrap-around, rollable and flexible panels, in several configurations.

BOE unveiled a new QD-OLED prototype at SID Displayweek 2020. This new panel is 13.6" in size with a FHD resolution. It supports up to 120 nits and achieves a 100% NTSC color gamut.

This is the first time we hear of BOE's QD-OLED project, this will be interesting to follow.

A report from Korea updates that three Samsung Display researchers in Suwon were arrested for allegedly leaking OLED technology. Directors of a Chinese company subsidiary were also arrested in this case

According to the report, the technology that was leaked relates to optical alignment of inkjet printing processes. Samsung reportedly invested over 10 billion won ($8.5 million) in developing this technology.
