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%.
