Quantum dots (QDs) have shown great potential for next generation displays owing to their fascinating optoelectronic characteristics. In this work, we present a novel full-color display based on blue organic light emitting diodes (BOLEDs) and patterned red and green QD color conversion layers (CCLs). To enable efficient blue-to-green or blue-to-red photoconversion, micrometer-thick QD films with a uniform surface morphology are obtained by utilizing UV-induced polymerization. The uniform QD layers are directly inkjet printed on red and green color filters to further eliminate the residual blue emissions. Based on this QD-BOLED architecture, a 6.6-inch full-color display with 95% Broadcasting Service Television 2020 (BT.2020) color gamut and wide viewing-angles is successfully demonstrated. The inkjet printing method introduced in this work provides a cost-effective way to extend the applications of QDs for full-color displays.

喷墨印刷的均匀量子点作为全色OLED显示器的颜色转换层。

量子点（QD）由于其引人入胜的光电特性，已显示出用于下一代显示器的巨大潜力。在这项工作中，我们提出了一种新颖的基于蓝色有机发光二极管（BOLED）以及图案化的红色和绿色QD颜色转换层（CCL）的全色显示器。为了实现有效的蓝绿色或蓝红色转换，通过利用紫外线诱导的聚合反应，可以获得具有均匀表面形态的微米级厚QD膜。均匀的QD层直接喷墨印刷在红色和绿色滤色镜上，以进一步消除残留的蓝色放射。基于这种QD-BOLED架构，成功演示了具有95％广播服务电视2020（BT.2020）色域和宽视角的6.6英寸全彩色显示器。
