The OLED Microdisplay industry is enjoying increased interest in the last few years, as the world's leading device makers (led by Apple, Facebook, Sony, Google, Samsung and others) are all developing next-generation VR and AR devices that are based on high-end microdisplays. OLED is regarded as the most fitting technology to power these next-generation devices.

Up until a few years ago, there was only a handful of companies that developed and produced microdisplays - led by eMagin, Sony, OLiGHTEK and MicroOLED, and the combined production volume was very limited, as applications were mostly in the defense, medical and high-end cameras sectors. But the increased demand spawned many more companies, some of which have already started to sell displays in the market, which expanded the global supply dramatically.

Researchers from Russia's Ural Federal University developed a new OLED emitters based on cyanopyrazine-enhanced fluorophores. The presence of cyanogroup substance in the composition of fluorophores significantly increases the efficiency of the OLED emitters.

The researchers say that they have modified the pyrazine-based push-pull system with cyanogroup and studied how this affected the photophysical properties of the fluorophores and the performance of OLED devices based on these materials.

TCL CSoT says that it has developed a new hinged-pixel design that can enable uniform stretchable displays.

The idea is to connect adjacent pixels with flexible hinges, so that when the display is stretched, the hinges make sure the pixels retain a fixed distance between them. The company says that this design can remain uniform for up to 40% expansion.

During Lenovo's Tech World 2022 event, the company and its Motorola subsidiary showed new device prototypes, including two interesting rollable OLED devices.

In the video above, you can see a new laptop prototype that has a rollable OLED display, that opens up to increase the screen size. There's also a smartphone that opens from a 4-inch display to a 6.5-inch one using a rollable display.

LG Display announced that its OLED TV and monitor panels has been recognized as having a perfect black level in any environment, from UL Solutions. The company received the new verification for its panels ranging from 42-inch to 97-inch.

LGD says that it is the only company that has been recognized in this verification for TV and monitor panels.

During the 2022 Light+Building tradeshow, OLEDWorks and Audi demonstrated a new OLED automotive rearlight unit:

The unit is Audi's latest rear model demonstrator of the A6 e-tron concept vehicle. The new concept features a significant increase in the number of OLED segments from what is currently on the road from Audi, and it looks like a beautiful concept.

The OLED microdisplay industry is enjoying high demand, and over the past years we have seen several new producers join the market, and new projects and developments. Here are some of the latest OLED microdisplay related industry news:

US-based Jet Aviation announced that it has delivered its quietest and lightest cabin interior to date. The VVIP interior uses six 55-inch curved WOLED screens, three on each side above the window line.

The company says that the new OLED displays were installed as of to reduce the cabinetry required to house the screens, providing further opportunity for reducing the weight of the cabin and maximizing the floor space of the interior.

According to reports from Korea, the OLED market is slowing down, as part of the overall weakness in the consumer electronics markets and specifically in the display market. It is reported that OLED TV sales dropped 18.1% in the second quarter, while in the second half of 2022, LGD's OLED TV panel shipments decreased by 11.4%.

The slowdown is also apparent in the OLED smartphone market, and DSCC estimates that 554 million OLED smartphones will ship in 2022, a 13% decrease compared to 2021.

Researchers from the Université de Rennes in France have developed a simplified PHOLED green emitter that achieves the world's highest efficiency in single-layer PHOLEDs - an EQE of 22.7%.

The researchers, led by Prof. Cyril Poriel, say that the emissive layer was developed using a rational molecular design. The impact of the phosphorescent emitter on the ambipolarity of the charge transport is particularly evidenced and appear as a key concept in the high performance that was achieved.
