We have developed highly transparent color liquid crystal display (LCD) using newly developed scattering‐type liquid crystal, which shows transparent state when voltage is not applied, with field sequential color (FSC) driving method without employing color filter and polarizer. Furthermore the light is directly introduced to the panel glass substrates from the edge of the substrates (not from back surface). At surface of the substrates, the light takes a total reflection by difference of refractive index between glasses and air. So the light propagates through the substrate. On the other hand, when a voltage as higher than a threshold voltage (Vth) is applied to liquid crystal (LC) layer, the light is scattered towards the viewers. This newly developed display has high transmittance (80%), wide color gamut and fast response time.
We have developed an error-diffusion dithering method for a reflective MIP LCD to provide a high-quality moving image. We have restricted error diffusing area within several segments defined on the image without deterioration of the image quality, and successfully resolved the fluttering problem in moving image.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
