Single-mode transflective liquid crystal display tailored for wide-band single gamma curve.
This paper proposes a single cell gap transflective patterned vertically aligned liquid crystal mode with the same gamma curve for both reflective and transmissive operation. The gamma curve of the proposed transflective mode is obtained by tuning the chevron-type electrode structure in the reflective part to diminish the difference of the optical polarization path on the Poincare sphere, between the transmissive and reflective parts. Wide-band characteristics can be obtained by using in-cell lambda/4 retardation films with different optic axes in the transmissive and reflective parts.
