Application of high efficiency phosphorescent OLEDs in both passive and active matrix displays

摘要

High-efficiency electrophosphorescent organic light emitting devices (OLEDs), based on triplet emission, is an enabling technology for low power full-color OLED displays. In addition, top emission OLED architectures can be used to maximize display aperture ratio and pixel current densities. In this paper we report on recent results in red, green and blue phosphorescent and top emission OLEDs and discuss the benefits that these attributes have on both active and passive matrix display performance.
