TCL CSoT shows a 14" inkjet printed QD-EL display, announced a $1 million prize to accelerate the technology

TCL CSoT demonstrated a 14" 2.8K inkjet-printed QD-EL display, that offers 30-120Hz VRR refresh rates and a 85% BT2020 color gamut. The impressive display won SID Displayweek's People's Choice Award.

TCL's CEO gave a keynote speech at Displayweek, saying how this is an early-stage technology that still has a lot of challenges before it can be commercialized - mainly the lifetime of the blue material. To encourage collaboration and innovation, TCL CSOT announced the Blue Star Project with a $1 million prize to incentivize collaboration and accelerate breakthroughs in QD-EL technology.

Researchers from the IBS in Korea developed intrinsically stretchable quantum dot LED displays

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.

DSCC: the QD materials market to reach $100 million in 2024, will grow to $122 million by 2027

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 demonstrates 12-inch and 30-inch QD-EL display prototypes

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.
