We review recent results form two types of small molecule organic light emitting devices (OLEDs). For flat panel display applications, we have developed a novel OLED pixel in which the R, G and B emission layers are vertically stacked to provide a simple fabrication process, minimum pixel size, and maximum fill factor. In separate experiments, we have worked towards achieving electrically- pumped organic lasers by demonstrating low-threshold lasing in an optically-pumped thin film double heterostructure consisting entirely of organic semiconducting materials.
