A full-color electroluminescent device and patterned photoalignment using light-emitting liquid crystals

The principle of combining liquid crystals and organic light-emitting diodes (OLED) technology to produce full-color OLEDs with enhanced capabilities was analyzed. The deposition and the photolithographic patterning of polymerizable and light-emitting liquid crystals using standard liquid crystal display (LCD) manufacturing procedures, to fabricate a three-color OLED, was described. A latest class of organic copolymers designed specifically as hole-transporting, photoalignment layers for OLEDs was discussed. The results demonstrate the viability of the polymerizable liquid-crystal approach to give full-color, high-information-content, large-area OLEDs, as well as to generate latest kinds of 3D OLEDs.Link_to_subscribed_fulltex
