摘要
利用LB(Langmuir-Blodgett)转移印刷技术成功制备了分辨率为12 700 ppi的高性能QLED(Quantum Dot Light-emitting Devices,量子点发光二极管)。通过该方法制备的超高分辨率红色QLED器件的EQE为15.27%。此外还成功制备了EQE为4.9%的超高分辨率白色QLED器件。本工作为下一代高分辨率显示器的实现提供了一种思路。
With the continuous development of near-eye display technology,the next generation display technology has more stringent requirements on resolution.In this work,a Langmuir-Blodgett transfer printing(LB-TP)technology was used to realize high-performance quantum-dot light-emit-ting diodes(QLEDs)with a resolution of 12700 pixels per inch(ppi).The external quantum efficien-cy(EQE)of the red QLED device prepared by this method was as high as 15.27%.In addition,a white ultra-high resolution QLED device with an EQE of 4.9%was successfully realized.This work could provide a route for manufacturing of the next generation high resolution display.
