摘要

Abstract

Micro-light-emitting diodes (μ-LEDs) are regarded as the cornerstone of next-generation display technology to meet the personalised demands of advanced applications

such as mobile phones

wearable watches

virtual/augmented reality

micro-projectors and ultrahigh-definition TVs. However

as the LED chip size shrinks to below 20 μm

conventional phosphor colour conversion cannot present sufficient luminance and yield to support high-resolution displays due to the low absorption cross-section. The emergence of quantum dot (QD) materials is expected to fill this gap due to their remarkable photoluminescence

narrow bandwidth emission

colour tuneability

high quantum yield and nanoscale size

providing a powerful full-colour solution for μ-LED displays. Here

we comprehensively review the latest progress concerning the implementation of μ-LEDs and QDs in display technology

including μ-LED design and fabrication

large-scale μ-LED transfer and QD full-colour strategy. Outlooks on QD stability

patterning and deposition and challenges of μ-LED displays are also provided. Finally

we discuss the advanced applications of QD-based μ-LED displays

showing the bright future of this technology.
