Liquid crystal displays backlit

Current flat-panel display technology primarily revolves aroimd inorganic LEDs, backlit liquid crystal displays (LCDs) and vacuum fluorescent displays. Although these technologies are trim and efficient compared with cathode ray tubes, they can be bulkier and much more power consuming than required for many applications. In many battery-operated devices, such as laptop computers, cellular telephones and other hand-held instruments, the illuminated display is the primary energy consumer. Furthermore, LED displays are expensive to fabricate because of the many individual diodes required to make up an alphabet, each with its own contacts and interconnections. These problems forced researchers to look for other materials.
