Mircocavity effects are restrained in white top-emitting organic light-emitting diodes (TEOLED). White emission TEOLEDs with high efficiencies of more than 15 cd/A and stable CIE coordinates within (±0.01, ±0.01) are fabricated on flexible PET substrates. Mechanisms on chromaticity stability are explored.
