Single Pixel Transflective Liquid Crystal Display with Cholesteric Half Mirror
We propose a transflective liquid crystal display (LCD) operated in a whole pixel configuration consisting of the single-polarized LC cell and the broadband cholesteric LC (ChLC) half mirror. The broadband spectrum ChLC film is used for a polarization-sensitive mirror which reflects a given circular polarization but transmits its orthogonal polarization. Our transflective LCD can be demonstrated by just replacing the polarizer, placed toward a backlight unit in the conventional cross-polarized LC modes, with the ChLC half mirror.
