Abstract

Liquid crystal display (LCD) is the most widely used display technology in our life, however there are still room to improve the color performance and energy efficiency. Quantum dots(QDs) have the advantages of narrow spectrum emission and high quantum efficiency, which play a key role in improving the color quality and perceived brightness of LCD display. This paper introduces the optical design of QD-LCD, the stability issues of QDs, as well as the challenges in backlight integration. Based on the analysis of QD-LCD’s requirements of low cost, low toxicity and easy integration, the industrial prospects of perovskite QDs are discussed. Finally, we present the future directions of QD-LCD, especially the problems of spectral cross of color filters and the energy loss of polarizer.
