Organic/polymer light-emitting diodes (O/PLEDs) are considered as one of the most potential and promising technologies in the 21st century due to their excellent characteristics including low energy consumption

wide visual view

colorful

fast response

environment friendly and the capability of being fabricated to flexible screen. White polymer light-emitting diodes (WPLEDs) have been attracting considerable attention due to their potential applications in large-area flat panel displays and solid-state lighting because they can be easily fabricated using wet processes

including the spin-coating

screen printing

and ink-jet printing techniques

which are expected to be lower in cost in mass production.In this paper

the domestic research progress on white-light-emitting-polymers and polymer white light-emitting diodes were introduced from two aspects.Besides

the application of this kind of diodes and the future of this research field as well as some questions which needed to be solved urgently were also discussed in detail.
