Abstract: Small-molecule-based organic light emitting devices (OLEDs) have been shown to have the brightness, range of colors and operating lifetime to be useful in full-color flat panel display applications. Recent technological advances have created exciting new opportunities for OLEDs in flat panel display applications. These include the development of a transparent OLED device for vehicular windshields, architectural windows, and 'head up' displays; a novel vertically-stacked OLED pixel structure that provides full- color tunability, minimum pixel size, and maximum fill factor for high-resolution displays; and an ultra- lightweight, flexible OLED for use in conformable or foldable displays. In addition, we discuss other development issues for the fabrication of high-resolution, full-color OLED displays. !24
