Abstract

Various advanced organic light-emitting devices (OLEDs) for enhancing performances of OLED displays, particularly active-matrix OLED displays, are reviewed in this paper. These include top-emitting OLEDs, inverted OLEDs, high-contrast OLEDs, microcavity OLEDs, and their combinations. How these device structures enhance display performances, such as color saturation, brightness or emission efficiency, contrast, and aperture ratio of pixels, etc., are discussed. The critical technical issues and the status of development associated with each device technology are reviewed.
