Electrical Annealing For Flexible Organic Light-Emitting Diodes Having Poly(3,4-Ethylenedioxythiophene):Poly(Styrene Sulfonate) Anodes: Spontaneous Buckling For Enhanced Light Extraction

We herein present efficient light emission from flexible organic light-emitting diodes (FOLEDs) having conductive polymer anodes on a polyethersulfone substrate. We have successfully demonstrated high bright and efficient solution-processed green FOLEDs, which show a peak luminescence of 14,900 cd/m(2) and a maximum current efficiency of 50.5 cd/A.
