Abstract

We realise pixels as small as sub-100 nm with ultrahigh pixel resolution up to 169,333 pixels-per-inch (PPI) over an electroluminescent area of 4 mm2. Benefiting from the closely packed light-emitting QD monolayers, our nano-QLEDs exhibit minimal performance degradation upon reducing the pixel size. Notably, the smallest red, green and blue nano-QLEDs maintain average external quantum efficiencies (EQEs) of 17.0%, 10.5% and 5.7%, respectively.
