摘要：

A simplified hybrid white organic light-emitting diode (WOLED) employing a p-type interlayer is designed, simultaneously realizing high efficiency, high color rendering index (CRI), low efficiency rolloff, low voltage and stable color. The device exhibits maximum total efficiencies of 29.8 cd/A and 20.91m/W, which slightly decrease to 28.6 cd/A and 16.5 lm/W even at a high luminance of 5000 cd/m(2). Besides, a slight color-shift and a CRI of 85 at 100 cd/m(2) (3.65 V) are obtained. Such superior results systematically demonstrate that the use of p-type interlayer is a new way to realize high-performance hybrid WOLEDs.
