Abstract: The quantum dot is a kind of semiconductor nanocrystal with quantum confinement effect, which attracts a lot of attention due to the excellent optoelectronic properties and has been widely used in the display area. The quantum dot become one of the core materials of display with several advantages including the high luminance efficiency, tunable emission wavelength, narrow FWHM and low-cost solution fabrication. Micro display technology is applied in the near eye display scenario with small effective display area (diagonal < 1 inch). Recently, the rising of VR/AR application scenarios require micro display technology with higher luminance, higher pixel density, and full color display. In this paper, we review the current progress of the quantum dot in micro display from photoluminescence and electroluminescence technique routes. The chances and challenges of the quantum dot in micro display are also summarized.
