  • Quantum dots are rising as suitable candidates in the field of display application due to their extremely high color purity, tunable emission spectra and high photoluminescence efficiency, especially for their contribution to the expanded color gamut in display technology. Motivated by the commercialization in the market, quantum dots based backlights have drawn great deal of attentions from both the scientific and industrial circles. In this paper, the research progress of quantum dot liquid crystal display backlight technology is reviewed, including the selection of quantum dots materials, the application of backlight structure and the development of composite materials and encapsulation technology. In addition, this paper also introduces the low-cost perovskite quantum dot optical film technology, which is widely concerned by industrial circle, especially the low-cost perovskite quantum dot optical film technology with independent intellectual property rights. This technology has the advantages of wide color gamut(124% NTSC), easy processing, and low cost with a great development potential.
