QuantumDots-Info is a knowledge hub focused on the Quantum Dots industry and markets, with a focus on quantum dots for displays.
China-based BOE has demonstrated a new 4.7" AMQLED display prototype, a self-emissive QD based panel.
The panel offers a resolution of 1440x2560 (650 PPI), a color gamut of 85% BT2020 and a high contrast ratio (rated at 10,000,000:1).
Samsung Display demonstrated its latest QD-OLED displays, in TV format (77-inch) and also in monitor formats. SDC's QD-OLED panel display won the SID Display of the Year award, and is indeed an impressive display. The company's latest QD-OLED panels offer new OLED materials, new optimized algorithms, and a maximum brightness of over 2,000 nits.
Besides the 77-inch TV, Samsung also showed 34-inch QD-OLED monitors, and 49-inch QD-OLED monitors with a ultra-wide aspect ratio (32:9).
Acer revealed its latest gaming monitor, the Predator X34 V. The monitor is based on a 34" 175Hz 3440 x 1440 curved QD-OLED panel, and it offers a 0.1 ms Gray-to-Gray response time, peak brightness of 1,000 nits, AMD FreeSync Premium comparability and VRR.
The Predator X34 V will ship in November 2023, for $1,299.
Researchers from Samsung Display, led by Changhee Lee, developed an all-inkjet-printed 12.4" full color 182 PPI EL-QD display, that offers improved performance.
The researchers say that by controlling carrier transport properties and charge balance through ligand exchange in QDs and ZnMgO surface, they were able to create this display that has a potential for low cost and material-consumption-efficient display manufacturing. The researchers will disclose the paper at SID Displayweek 2023 next week.
Quantum Dots developer Nanosys announced a milestone in QD technology commercialization - the 1,000th unique display product that utilizes its QD materials. Nanosys says that it has shipped over 140 tons of QD materials and it holds more than 800 unique patents.
Nanosys offers QD solutions for LCDs, OLEDs, microLEDs and QD-EL displays (which it calls nanoLEDs). The company’s tier-one customer base includes all top-10 global television brands and four of the top-five IT brands, including Samsung, LG, Sony, VIZIO, TCL, Hisense, Acer, ASUS, and Phillips.
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:
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.
Sony launched new QD-OLED TVs for 2023, the A95L series. The A95L offer 55", 65" or 77" 120Hz 4K panels, Sony's XR processor, Pentonic 1000, Acoustic Surface Audio+ and Google TV platform.
Sony did not yet announce the price and availability of its A95L OLED TVs.
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.
