Microfluidics-based quantum dot color conversion layers for full-color micro-LED display

Applied Physics Letters, 2021
In this study, quantum dot color conversion layers (QDCCLs) for full-color micro-LED display were successfully fabricated using microfluidics to conduct red and green perovskite quantum dots to the position of the pixel array. The QDCCL with full-color pixel size of 200 × 200 μm and sub-pixel size of 140 × 50 μm was achieved.

Reduced Self‐Absorption of Quasi‐2D Perovskites and Their Application in Color Conversion Layers

Advanced Optical Materials, 2022
AbstractLead halide perovskites (LHPs) have recently demonstrated great potential for color conversion layers (CCLs) in backlight displays due to their ultrahigh color purity and high photoluminescence quantum yield. However, the severe self‐absorption effect of LHPs due to small Stokes shift restricts their optical conversion efficiency (OCE) as CCLs.
