摘要
量子点显示器件具有高光谱纯度、宽色域、高亮度等优势,被认为是显示行业未来的一个重要发展方向。发展量子点高精度光刻图案化技术对实现其在显示领域的应用具有重要的意义。本文阐述了量子点光刻技术的最新进展,主要包括光刻胶辅助剥离光刻和直接光刻技术。在直接光刻技术方面,着重介绍混入光刻胶光刻和配体工程光刻,并对图案化的量子点发光层在光致发光和电致发光中的应用进展进行评述。同时,介绍量子点光刻中存在的问题并展望其在超高分辨率显示领域的应用前景。
Quantum dot(QD)light-emitting diodes(LEDs)are considered as a promising direction for next-generation display applications because of their excellent spectral purity,wide color gamut,and high brightness.However,developing a technology for high-resolution patterning of QDs remains challenging.This paper expounds the latest progress of QDs photolithography technology,including lift-off photolithography and direct photolithography technology.In the direct photolithography technology,we are focusing on the mixed photoresist and ligand engineering photolithography,we also introduce the progress of patterned QDs luminescence layer in photoluminescence and electroluminescence application.Finally,we provide the problems in QDs photolithography and our outlooks for potential future directions in the field of ultra-high resolution display.
