(a) Photos of flexible SLG-WOLEDs and an high brightness SLG-WOLED illuminating coloured objects. (b) Emission spectrum of WOLEDs on SLG and ITO. (c) EQE of SLG-WOLEDs on various substrates with high index lens for enhanced light out-coupling. (d) PE and CE of SLG-WOLEDs and ITO-WOLEDs with enhanced light out-coupling. The error bars represent the s.d. of multiple measurement results.
