BOE developed an Oxide-TFT 55" 8K AMQLED display

BOE Technology Group unveiled a 55" 8K AMQLED device, which is said to be the world's first such display. The display is based on QD emitters, and uses an active-matrix Oxide-TFT backplane.

BOE says that all functional layers, except the cathode, were deposited using inkjet printing.

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%.

SmartKem and Nanosys to co-develop OTFT-based emissitve QD displays

UK-based OTFT-developer SmartKem and QD pioneer Nanosys announced a joint-development project to work on low-cost printed QD displays, that will combine SmartKem's printed organic TFT with Nanosys' quantum dots emitter platform.

Nanosys now refers to its emissive (electroluminescent) QD technology as nanoLED. Both technology platforms, the OTFT backplane and the NanoLED frontplane are solution-based, which could indeed result in a low-cost production process.

UBI Research: Samsung has almost finalized its QNED development

Market Analysts from UBI Research say that following an analysis of 160 patents filed by Samsung Display related to its quantum dot nanorod LED (QNED) technology, it has come to the conclusion that SDC has has completed the development of the QNED display structure.

UBI says that Samsung still needs to find a way to maintain the number of aligned nanorod LEDs within each pixels, though, so the development is not finished yet.
