Design of calcite-doped random depolarization films for real-color displays

Liquid-crystal displays and organic light-emitting diode displays cause a blackout problem or a color change problem, viewed through polarized sunglasses. The random depolarization film (RDF), a polymer film doped with calcite particles, improves both the problems of the displays and contributes to realizing real-color displays. However, RDF degrades sharpness of the displayed image owing to light scattering by the dopant particles. In this study, we achieve RDF that improves the image sharpness by utilizing directional forward scattering caused by micro-sized particles. In the conference, we will discuss the optimization of the dopant size in RDF for realizing real-color displays with the sharp image.
