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).
NanoPalomaki posted an interesting teardown video of Samsung's S95B QD-OLED TV. You can see the sub-pixel structure of the OLED TV:
This is only the first part of the teardown, we'll see what is revealed in the second part.
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.
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.
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%.
