摘要

有机电致发光显示器（OLED）因具备低功耗、自发光、高柔性、色彩丰富和响应速度快等优势，被认为是未来显示的发展方向。随着压电喷墨打印的无接触、液滴精准定位和大面积快速印制等技术的引入，使得大尺寸OLED的量产应用成为可能。印刷喷射过程中的液滴均匀性对高质量OLED功能层的形成起着至关重要的作用，为此，本文综述了压电印刷OLED性能优化方法，主要从脉冲波形的优化、控制系统的自修复和油墨的流变特性调控来进一步提升液滴喷射性能，并进一步列举了压电印刷OLED在显示与照明领域中的应用。

Abstract

Organic electroluminescent display (OLED) is considered to be the development direction of future display due to its advantages of low power consumption

self-luminescence

high flexibility

rich colors and fast response speed. With the introduction of technologies such as piezoelectric inkjet printing

such as non-contact

precise positioning of droplets

and large-area fast printing

mass production applications of large-size OLEDs have become possible. The uniformity of droplets in the printing and jetting process plays a vital role in the formation of high-quality OLED functional layers. For this reason

this paper reviews the performance optimization methods of piezoelectric printing OLED

mainly from the optimization of pulse waveform

self-healing control system and rheological characteristics of the ink to further improve the droplet injection performance

and further cited the application of piezoelectric printing OLED in the display and lighting fields.
