ABSTRACT
The driving force for the fast development of light-emitting polymers is closely linked with their potential for applications in various fields [110]. It has been shown that PLEDs can emit different colors with good efficiency (1-4%) at low voltages. They are light and flexible and can be easily processed to form large-area, robust films. The response time for PLEDs is fast (usually submicrosecond), and the in tensity of light is proportional to the current. It is obvious that PLEDs have great potential as a new lighting source, for small-scale instrumental displays, and ulti mately in large-area, full-color flat-panel displays. The potential market for flatpanel displays is at least $10 billion/year.
