Abstract: Due to high quantum efficiency, narrow spectral emission, unique size-tunable spectra and excellent solution-processcompatibility, quantum dots have great potential in high-color-quality display. With deep exploration on mechanisms of excitation and attenuation, improvements of quantum yields, structural optimization of devices and effective transportation of charge carrier, external quantum efficiency of quantum-dot electroluminescent devices have been increased from less than 0.01% to about 20.5%, which is very close to the value of commercial OLEDs. In the long term,quantum-dot electroluminescent technology will transcend the photoluminescence brightness enhancement film and color filter products, and it is expected to become the next-generation display technology. Along with the link of “materials to device to panel”, this review first outlines the properties and categories of quantum dots. Next, the structures, types,mechanisms of devices are summarized. The key scientific and technological challenges of commercialization of quantum-dot display are finally identified.
