High contrast ratio, scattering index of LC, optimized liquid crystal, critical point

We quantitatively investigated the relation between the luminance in the black state and scattering index of liquid crystal, in order to choose optimized liquid crystal to improve the contrast ratio. It was found that scattering index decreased from 0.345×105m/N to 0.137×105m/N, the contrast ratio would improve from 1000:1 to 1800:1.
