摘要

随着有机电致发光显示（OLED）技术的不断发展，OLED在智能手机、智能手表和电视等市场应用不断扩大。尤其是在小尺寸智能手机市场，OLED已成为主流的显示技术，并有望逐步替代LCD技术。但在中大尺寸显示产品如平板电脑、笔记本、显示器、电视等应用领域，受限于目前真空蒸镀工艺的高成本及可靠性问题，发展较为缓慢，但市场对其需求依然很高。相比于真空蒸镀技术，通过喷墨印刷技术制备显示器件，可极大地提高材料利用率，降低设备成本，且由于其是一种增材制造方式，可减少资源消耗和环境污染，更有利于实现大面积、轻、薄、柔的显示屏制造。本文介绍了用于喷墨印刷OLED的各功能层材料研究进展，并对印刷OLED器件结构、制备工艺及器件性能进行了讨论，最后对印刷OLED的发展前景进行了展望。

Abstract

With the continuous development of organic light emitting diodes （OLED）， the application of OLED in markets such as smartphones， smart watches， and TVs continues to expand. Especially in the small-size smartphone market， OLED has become the mainstream display technology and is expected to gradually replace LCD technology. However， in the application fields of medium and large size display products such as tablets， notebooks， monitors， TVs， ,etc,.， limited by the high cost and reliability of the current vacuum evaporation process， the development is relatively slow， but the market demand for them is still very high. Compared with vacuum evaporation technology， the preparation of display devices by inkjet printing technology can greatly improve the utilization rate of materials and reduce equipment costs. And because it is additive manufacturing， it can reduce resource consumption and environmental pollution， which is more conducive to the realization of large-size， light， thin and flexible display manufacturing. This paper introduces the research progress of various functional layer materials for inkjet printing OLEDs， and discusses the device structure， preparation process and device performance of current printed OLEDs. Finally， the development trends of printed OLEDs are prospected.
