dc.description.abstract We have applied a simple cross-patterning technique for the fabrication of phosphorescent white organic light-emitting diodes (WOLEDs) with red, green and blue (RGB) emitters; the resulting device has relatively low driving voltage and high colour stability. The selectively cross-patterned multicolour emitting layer (EML) was easily prepared using a metal mask without an alignment process. Not only was the characteristic of low driving voltage obtained but also of improved colour stability, which can be ascribed to the simplified stack of the EML and the corresponding suppression of the biased shift in the recombination zone. The spatial distribution and variation of the stacked EML structure could explain the origin of the robust white emission. Compared with the conventional WOLED with a RGB simple stack, the cross-patterned multi-EML device showed a slight change in colour coordinates in the luminance range 1008000cdm 2, with a decrease in the driving voltage of 0.52.0V, while the luminous efficiency was maintained. © 2012 IOP Publishing Ltd. -
