Polymer Light Emitting Diodes (PLEDs) and Organic Light Emitting Diodes (OLEDs) have made great progress in terms of efficiency, brightness and lifetimes during its last few years of development. The technology looks mature enough to produce real commercial products like high-resolution flat panel displays for cell phones, computers and televisions. However, it is also quite promising for low information content displays. In this work, the technology of low information content displays like 7-segment and simple billboard type of displays using polymer and small molecules has been developed. The processes, structures, characteristics and advantages of OLEDsand PLEDs over LCDs and inorganic LEDs are presented.
