What is it about?
White organic light-emitting diodes (WOLEDs) have huge potential in flat-panel displays and solid-state lighting application. A hybrid WOLED, with an ultra-high CRI of 96, a high EQE of 19.34%, and good color stability was develpod.

Why is it important?
By employing simple device structure without the introduce of doping process, we demonstrated the first WOLED with good tradeoff among device efficiency, CRI, and color stability. These results indicate that the proposed novel architecture would be an effective way to develop low-cost, high-efficiency/CRI/color stability WOLEDs with unique and simplified structures for a wide range of next-generation lighting applications.
Perspectives
The proposed novel concept would provide an effective way to develop high performance WOLEDs with simplified structure and a low cost for next-generation lighting application. I hope this work will provide a guidance towards the developments of simplified but high-performance hybrid WOLEDs.
