Quantum dots (QDs) have been successfully applied in the liquid crystal display (LCD) industry for 10 years. With the developments of quantum dot diffusion plate, QD-OLED technology and perovskite quantum dots, QD-LCD has experienced a rapid development, making QDs an important driving force to promote LCD industry. Except for the enhanced color gamut, QD-LCD also plays an important role in the aspects of eye protection, energy saving and so on. This review summarizes the current progress of QD-LCD display application with a discuss of the future perspective. This paper will be helpful to the engineers working on the display technology.
