Paper Abstract

A new type of display equipped with a transparent screen was proposed. One can see the background of the display through the screen on which the information is displayed. The see- through display was constructed by two main components; a polymer dispersed liquid crystal (PDLC) panel and an illuminating unit with an edge-lit hologram. The OFF pixels in the scattering mode of the PDLC were illuminated by monochromatic light from the illuminator to display necessary information and/or patterns. The other part of the display was clear and the background was observed through the display because the ON pixels as well as the illuminator were transparent. The design to realize the multi-color display as well as the process to make quality edge-lit holograms were also discussed.
