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).
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.
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%.
BOE Group, founded in 1993 in Beijing, China, is the world's largest display producer. BOE makes both LCDs and OLEDs. BOE also produces LCD backlighting units and solar panels.
BOE produces Quantum Dots enhanced LCDs. In addition the company develops QD-OLED panels and QDEL panels (which the company refers to as AMQLED).
