摘要：
Color stability of white organic light-emitting diodes was improved by using a charge confining device structure, which can confine charges at the center of the emitting layer. A red phosphorescent emitting layer was sandwiched between blue phosphorescent emitting layers and there was little change of color coordinate from 100 to 10 000 cd/m(2).
