• Kyulux says it is on track to commercialize green Hyperfluorescence materials in 2023, red and blue in 2024

Kyulux gave a very upbeat presentation at SID Displayweek, during which it updated on its latest material specification and its commercialization plans.

Kyulux managed to increase the lifetime of its Hyperfluorescence emitter systems (which features an IQE of 100% and a narrow emission spectrum) quite dramatically in the past year its green material now offers a lifetime of 59,000 hours (LT95@1000 nits, top emission), while the red material is at 20,000 hours. The blue material has also increase from280 hours to 450 hours in the past year.

DSCC says that global OLED revenues in Q1 2022 were around $9.5 billion, the same as in Q1 2021, even though unit shipments declined 4%.

Smartphone remained the leading OLED application, with a 79% revenue share, even though shipments decreased 8% (and revenues decreased 3%). The second largest application by shipments is wearables (16% in Q1 2022 by shipments and in 6% market share by revenues).

OLED microdisplay maker eMagin has shown its latest 2.1" 4K (3600×4000) 120Hz OLED microdisplay prototype at SID Displayweek 2022.

As you can see in the image below (click to enlarge), the board says "STEAMBOAT", which lead some analysts to speculate that one of eMagin's VR customers is game developer Valve Corporation (as they publish the STEAM gaming platform).

Idemitsu Kosan announced that it has developed the world's most efficient blue fluorescence OLED emitter system. Idemitsu's new system achieves an EQE of 14% (at current density of 10 mA/cm²), a lifetime of over 400 hours (LT95 @ 50 mA/cm²) and a color point of (0.14,0.08).

The new material system uses a tandem structure of two blue OLED emitter layers. Idemitsu says that by separating the region that causes charge recombination and utilizing TTF (Triplet-Triplet Fusion) it managed to achieve the high light output.

Japan Display (JDI) announced that it has developed a new OLED deposition technology, which they refer to as eLEAP, that is cost effective and can be used to create OLEDs that are brighter, more efficient, and longer lasting compared to OLEDs produced using mask evaporation (FMM). eLEAP also enables OLED freeform deposition. JDI regards its new technology as a " historic breakthrough in display technology".

eLEAP is based on a lithographic method, and does not require any masks. The main advantage seems to be that OLED displays produced by eLEAP technology can achieve an aperture ratio of 60%, compared with FMM OLEDs which achieve a ratio of about 28%. This means that the OLED displays can be driven at lower currents - which extends the lifetime, improves the efficiency and also enables higher-peak brightness when needed.

BOE is showing a new flexible and transparent display prototype at SID Displayweek, this is something we did not see for several years.

The display on show is a 12.5" panel that offers a transmittance of up to 45%. The brightness is 700 nits, and the pixel density is 80 PPI. BOE says it developed a unique pixel scheme to enable the transparency of this display.

LG Display says that according to an original research it has conducted, OLED is the optical gaming display technology.

In this research, several gamers played different gaming genres on LCD and OLED displays, and on curved and flat displays. The study results show that a gamer’s reaction time can be improved by using OLED, while a display’s curvature provides a more immersive gaming experience.

BOE demonstrated its latest OLED technologies and displays at SID Displayweek 2022. The most interesting display is a 95-inch 8K HDR OLED display, produced on an Oxide-TFT panel with a white-OLED CF structure. The panel was produced using an evaporation method.

This is the first time we hear of BOE's evaporation TV program, since around 2016. The company has an active inkjet printing OLED TV project, and in December 2019 it unveiled a 55" 8K (160 PPI) printed OLED TV prototype.

OLED microdisplay maker eMagin reported its financial results for Q1 2022, with a strong quarter. Revenues were $7.4 million (up 9% from 2021), as production increased 27% compared to 2021. The company's operating loss declined to $1.2 million ($2 million in Q1 2021), and its net loss was $0.1 million ($1.3 million adjusted for changes in warrant liability).

eMagin reported strong bookings, and an open orders backlog of $13.6 million.
