Inkjet printing developer Notion Systems has started to construct a new company headquarters in Schwetzingen, Germany, with a new production plant. The company recently held a groundbreaking ceremony of the new building which will have 3,600 m² of floor space.

Notion Systems is growing at a rate of 20% per year, and these new premises are needed to cope with its increasing number of orders. The company estimates that 18% of its revenue in coming years will be generated from the display industry, for which the company offers machines for inkjet printing of QLED and OLED displays.

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.
