Simulation study on the optical properties of hybrid films adopted in quantum-dot edge-lit backlights for LCD applications

A new hybrid optical film integrating several optical functions was adopted in a quantum-dot (QD) backlight for liquid crystal display applications. The hybrid film included two prism sheets and one reflective polarizer between which index-matching layers were inserted. The optical performances of t...

Description
Summary:A new hybrid optical film integrating several optical functions was adopted in a quantum-dot (QD) backlight for liquid crystal display applications. The hybrid film included two prism sheets and one reflective polarizer between which index-matching layers were inserted. The optical performances of the hybrid QD backlight were comparable to those of a conventional QD backlight where optical films were separately adopted. The on-axis luminance decreased slightly while the viewing angle became enhanced by adopting the hybrid film. The color gamut of the present hybrid QD backlight was more than 100% according to the National Television Standards Committee standard. The hybrid film suggested in this study can be used to reduce the number of optical films substantially and, thus, the fabrication process of backlights.
