摘要

We have developed full colour top emitting quantum dot light-emitting diode (QD-LED) display driven by a 176-ppi active matrix of metal oxide thin-film transistors. Red, green and blue (RGB) QD-LED subpixel emission layers are patterned by our original UV photolithography process and materials. We also demonstrate the potential to achieve high resolution such as 528 ppi using this process.
