P-114: Achromatic Dark State of MVA-LCDs with a Negative C-Plate and a Biaxial Film

We propose a new approach to achieve achromatic dark state of MVA‐LCDs using a negative C‐plate and a biaxial film. In comparison to conventional approach which uses a negative C‐plate and a positive A‐plate, our design shows that the maximum light leakage over entire viewing cone is reduced by ∼6X...

Description
Summary:We propose a new approach to achieve achromatic dark state of MVA‐LCDs using a negative C‐plate and a biaxial film. In comparison to conventional approach which uses a negative C‐plate and a positive A‐plate, our design shows that the maximum light leakage over entire viewing cone is reduced by ∼6X at 450 nm and ∼4X at 650 nm. The achromatic dark state is essential for improving the contrast ratio, viewing angle and color saturation of MVA LCDs.
