BOE shows a TADF-sensitized Tandem AMOLED device prototype

During the company's Innovation Partner Conference, BOE demonstrated a new 6.55" OLED panel prototype that utilizes TADF-sensitized materials and a tandem stack architecture. The company says that the TADF materials offer significantly improved color gamut, and it achieve 95% BT.2020 coverage, this in addition to the high power efficiency and long lifetime. 

It is our understanding that BOE's TADF-Sensitized material platform combines a deep green Hyperfluorescence emitter and a standard deep-red phosphorescence material. The blue emitter is likely a standard fluorescence bluet emitter.

 

Basically the main innovation is the green hyperfluorescence emitter, which as combines high efficiency (100% IQE) with a narrow-emission spectrum, which is superior to the emission spectrum of both PHOLEDs and TADF materials. This enables HF emitters to offer a better color gamut and higher-efficiency.
