Abstract

The next generation of advanced displays must have flexible form factors and high-definition red, green, and blue (RGB) pixels. Here, we demonstrate full-color, ultrahigh-resolution nanocrystal patterning for ultrathin wearable displays. The development of double-layer dry transfer printing of the PeNC and organic charge transport layers prevent internal cracking during the transfer printing procedure. As a result, 100% transfer yield RGB pixelated PeNC patterns with up to 2,550 PPI and monochrome patterns with up to 22,450 PPI are produced. The perovskite light-emitting diodes (PeLEDs) with transfer-printed active layers demonstrate exceptional electroluminescence properties and have the highest reported external quantum efficiency of printed PeLEDs at 14.8%. Moreover, the manufacture of extremely thin multi-color PeLEDs is made possible by double-layer transfer printing.
