Design of random depolarization film using various birefringent particles for real-color displays

Le résumé fourni par la source

Liquid-crystal and organic light-emitting diode displays emit linearly polarized light, which causes blackout and color change problems when the displays are viewed through polarized sunglasses. To address both the blackout and color change problems, we proposed a random depolarization film (RDF), a polymer film doped with birefringent microparticles. Owing to the birefringence of randomly dispersed particles, the RDF converts linearly polarized light to randomly polarized light. In this study, to realize real-color displays with the RDF, the dopant particles were investigated based on a retardation, which is defined as a product of a birefringence and thickness of the dopant particles.
