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%.
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.
Here's a nice video from Insight Media, showing Nanosys' booth and technologies at DisplayWeek 2022.
You can see several QD-ehhanced LCDs, a prototype microLED microdisplay by glo (which Nanosys recently acquired), and a side-by-side comparison of Samsung's QD-OLEDs and LG's WOLED TVs. You can also see the new xQDEF laminate films developed with Bready.
