Quantum Dots technology is being used today in many display applications (mostly in LCD and OLED displays), and it is expected that adoption QDs in the display industry will continue to grow quickly. Here are some recent and popular news that you may find of interest:

• DSCC: QD-OLED TV market will grow to 1.5 million units in 2026
• Newly-developed perovskite QDs are promising for display color conversion applications
• Samsung Display completes the switch to a full-fledged QD-OLED centered business
• NanoSys demonstrates a 6-inch QD-EL display, brands the technology as NanoLED
• DSCC sees QD display production growing 15% in 2023, with further growth ahead
• Samsung announces new QD-OLED panels and products
• Philips launches a QD-OLED gaming monitor
• Amazon launches its own brand of QD-enhanced LCD TVs
• Samsung said to increase QD-OLED capacity to produce monitor panels for Apple
• LG Display invests $2.1 million in QD film developer InnoQD

Researchers from Kyung Hee University and the Korean Institute of Science and Technology have demonstrated that a low-temperature processed PTAA hole transport layer (HTL) can improve the performance of flexible light emitting quantum dots (QD-EL, or QLEDs) - produced on plastic substrate.

The researchers say that using a low-temperature process ensures that the flexible substrate is not deformed. Such QLED devices suffer from low performance compared to glass based devices that use optimal PTAA HTLs, but the new process and materials improve the flexible devices closer to glass based ones.

DSCC says that QD displays (QD-OLED and QD-LCD) will continue to grow, with area growth of nearly 15% in 2023. The largest application for QD displays by far is TV, with 15.6 million QD-enhanced TVs to ship in 2023.

Regarding QD-OLED panels, DSCC notes that the only producer today is Samsung Display, that has a converted LCD line with plans to reach a capacity of 45,000 8.5-Gen substrates per month by 2025. The company did not yet commit to further investments. QD-OLED production, by area, will reach 1.7 million square meters in 2025. QD-LCD panel area will reach 23 million square meters in the same year.

Quantum Dots developer Nanoco Technologies announced that Samsung Electronics agreed to pay $150 million USD in settlement for a patent lawsuit over a technology used in Samsung's quantum-dot LED TVs.

The two parties reached the settlement shortly before the start of the trial last month. The settlement includes a license agreement and the transfer of "certain patents" and settles all related proceedings.

Samsung Electronics reported its financial results for Q4 2022, with revenues of $57.3 billion, and an operating profit of $3.5 billion.

Amid a tough business environment, Samsung says that its large-area display unit loss was lower as it is increasing its QD-OLED panel sales. In addition, Samsung says that it exhausted its LCD inventory, completing the switch to a full-fledged QD-OLED centered business.

According to a report from Korea, Samsung has updated its QD-OLED material stack (now called QM2). The new stack adds a new ETL layer to the green OLED emitter.

Samsung also started to recycle the waste materials used in the production process. Finally, UBI reports that Samsung is set to increase its production capacity from the current 30,000 monthly substrate to 45,000 monthly substrates by 2024 (this was already hinted at in November 2022).

According to reports, Nanosys demonstrated a QD-EL (QLED) display at CES 2023 in a private room. The company showed a 6" display. This was an early prototype - the company said that it won't have a commercially-ready blue QD emitter by 2025/2056 at the earliest.

Nanosys brands the technology as NanoLED.

There are reports from Korea that say that the Korean Government is considering designating quantum dots display technology as a "national strategic technology", which means that companies will be given tax benefits, to encourage further investments and R&D.

According to the reports, next week the government will unveil a new draft tax law next week that will also include OLEDs and microLEDs displays as strategic technologies.

Update: TCL says it issued that statement by mistake, and it has no current plans to ship a QD-OLED TV in 2023

TCL says that later in 2023 it will launch its first QD-OLED TVs, which will make it the third company (after Samsung and Sony) to offer these TVs.

TCL did not give any more details on its upcoming QD-OLED lineup.
