Considering the imminent global energy crisis and inefficient energy utilization, energy-efficient organic light-emitting diodes (OLEDs) are considered one of the most competitive candidates for displays and particularly for future energy-saving lighting sources. Full color displays require all primary colors: red, green, and blue (RGB). In recent decades, numerous phenanthroimidazole (PI) RGB-emitting materials have been developed for efficient OLEDs. In organic electronics, considerable interest is shown on PI, due to ease in fluorophore modification. This chapter focuses on the design and synthesis of PI-based materials and their applications in OLEDs. At first, some nondoped blue, green, and yellow fluorescent materials are comprehensively studied. Then attention has been paid for typical blue, green, yellow, orange, and red PhOLEDs of PI-based fluorophores as a host materials are briefly presented. The molecular design concept, general synthetic routes for PI materials, and the applications of fluorophores in fluorescent OLEDs and host materials in PhOLEDs are reviewed.

A full color 2.2″ passive matrix organic light-emitting diodes (OLEDs) with 128 (RGB) * 160 pixels was developed. The display features that driving circuit can transform 18 bits gray-scale data from a PC to the OLED panel via a DVI channel. The size of the pixel was 240μm240μm, while that of mono sub-pixel is 190μm45μm. The lifetime of panel was estimated over 5000h because of the use of dual-scan driving technology, and the power consumption of the display was 300mw about when the average luminance of panel reach 40cd/m2.
