Quantum dots design for display applications

Quantum dots technology enhances light emitters and becomes increasingly important in display applications for providing higher luminance and larger color gamut. When light passes through a film with quantum dots, the light is scattered or absorbed, and a portion of the absorbed light is re-emitted at a different wavelength. The photon events within quantum dots, on the macroscopic level, can be described probabilistically using rays with unconverted or converted wavelengths. When the rays exit the material, metrics can then be evaluated from the ray data to assess display performance. Therefore, by varying the parameters of the quantum dots, the performance of quantum dot displays can be optimized. In this paper, we discussed how scattering events are modeled in quantum dots, explain a few display performance metrics, and describe an example of quantum dot display design.
