Researchers from Korea's Institute for Basic Science, led by Professor KIM Dae-Hyeong, published a new article in Nature that details intrinsically stretchable quantum dot LEDs. 

The researchers say that using current technology, making stretchable light-emitting devices results in poor luminous performance. The researchers now produced the intrinsically stretchable QD-LEDs using a mechanically soft and stretchable emissive layer consisting of a ternary nanocomposite of colloidal quantum dots, an elastomeric polymer and a charge transport polymer.

Samsung Display recently decided to move around 500 engineers from its large-area QD-OLED business unit to its small-and-medium sized AMOLED business unit. This move could signal a change in SDC's confidence in its QD-OLED technology.

A new article at OLED-Info discusses the technology and market challenges of QD-OLEDs, the recent activities in the display industry and market - and states that Samsung may be not invest further in its QD-OLED technology.

DSCC says that the demand for QD materials in the display industry is growing, and the market will grow to $100 million in 2024. It will continue to grow and reach $122 million in 2027. 

The main application is in LCD displays (color conversion), but materials used in QD-OLED's (by Samsung Display) is growing and accounts for 31% of the market (in the chart above DSCC notes QD-OLEDs as QD-CC). Production of QD-OLED panels is limited (SDC's total capacity is for around 2 million panels per year) but the material usage is large compared to QD-LCDs.

Sharp was demonstrating two new QDEL prototype at CES 2024. The first was 12-inch in size (you can see this in the video below), and the second a 30-inch prototype (Sharp did not allow to take photos/videos of the larger display).

Sharp did not disclose much about the display, or any commercialization plans. This seems to be an early-stage development. We do know that Sharp is using QD materials produced by Nanosys (SHOEI), and that the display is produced on an IGZO (Oxide-TFT) backplane.

During CES 2024, several device makers announced new TVs and monitors based on Samsung Display's QD-OLED panels. It seems as if market acceptance for SDC's high-end QD panels is on the rise:

• Samsung Odyssey 2024 gaming monitors (27" 1440p 360Hz / 32" 4K 240Hz / 49" 5120x1440 240Hz QD-OLED
• Samsung S95D, S90D, S85D (QD-OLED and WOLED TVs)
• Gigabyte AORUS 2024 QD-OLED monitors (27", 31.5", 34" QD-OLEDs)
• HP Omen Transcend 32 gaming monitor (32" 240Hz 4K QD-OLED)
• Dell Alienware AW2725DF / AW3225QF monitors (27", 32" QD-OLEDs)

TCL announced what it says is the world's largest miniLED backlit QD display - the QM8 (Model 115QM89). This 115" TV offers 20,000 local dimming zones, TCL's AIPQ Ultra processor,  a 6.2.2 channel speaker system, and the company's High Brightness Ultimate LED backlighting, which can produce up to 5,000 nits of peak brightness.

TCL did not yet disclose the price or availability of the 115" QM8.

Korea-based automotive component supplier Hyundai Mobis announced that it has developed a premium vehicle display combining Quantum Dots and Local Dimming technologies. The display is 27-inch in size. The company refers to this display as QL (Quantum dots and Local dimming).

The company says that this is the first such display in the world, and that it offers enhanced color reproduction thanks to the quantum dots technology, and higher contrast thanks to the local dimming technology.
