英文摘要：

Ink-jet printing technology has attracted considerable attention in recent years due to its non-contact, precision dispensing capability and high resolution. It offers a practical and economic manufacturing process for polymer light emitting devices （PLED） industry due to low cost, large area processing, and multicolor addressable capabilities. In this article, the progress in film preparation of electroluminescent polymers by ink-jet printing in PLED fabrication has been reviewed. The current issues related to polymer ink rheology and film uniformity were also discussed.
