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.

Korean researchers demonstrate a highly flexible ultrathin QLED device

Researchers from Seoul National University developed an ultrathin QLED device, that can be folded just like a paper. The researchers demonstrated a 3D foldable QLED, which can be produced in customized 3D structures.

To produce the device, the researchers developed a new fabrication process, that can partially etch the epoxy film deposited on the QLED surface without damaging the underlying QLED. This changes the QLED film from a planar shape to the 3D foldable shape.

BOE shows a 55-inch 4K emissive QD display prototype at SID Displayweek 2021

China-based BOE shows its latest emissive-QD display (AMQLED) at SID Displayweek 2021:

The 55-inch display offers a 3840x2160 (4K) resolution, a contrast ratio of 1,000,000 : 1 and a wide color gamut (90% BT2020). BOE says that all the functional layers of this display (HIL, HTL, QD and ETL) were ink-jet printed which enable BOE to achieve a material utilization rate of over 90%.
