Ultrafast response time, high resolution, high luminance, and a dynamic range for outdoor use are all important for non-pixelated, pupil-forming optics. The current mainstream technologies using liquid crystals and organic materials cannot satisfy all these conditions. Thus, finely patterned light-emissive solid-state devices with integrated circuits are often proposed to meet these requirements. In this study, we integrated several advanced technologies to design a prototype microscale light-emitting diode (LED) arrays using quantum dot (QD)-based color conversion. Wafer-scale epilayer transfer and the bond-before-pattern technique were used to directly integrate 5-µm-scaleNature communicationsQuantum dot-integrated GaN light-emitting diodes with resolution beyond the retinal limit.PMC89868352017R1C1B20122272018R1A6A1A0302570820191395Lee SHan MJeon DChoi YLim JKim IYoo HShin YBae JfalseQuantum dot-integrated GaN light-emitting diodes with resolution beyond the retinal limit.Near-eye display technology is a rapidly growing field owing to the recent emergence of augmented and mixed reality.
