Quantum dot (QD) enhanced LCDs are among today’s best‐in‐class displays exhibiting high brightness and large color gamut. In this presentation we focus on the underlying key mechanism of the embedded QD films, the down‐conversion of light, and explore the optical characteristics of a state‐of‐the‐art perovskite QD film by measuring its down‐converting properties as a function of the viewing angle. The good agreement of the experimental results with simulations of the QD film indicates that computer aided parameter optimization can be key tool for engineering QD displays.
