In recent years, and for the next generation of TVs and monitors, increasing resolution is a key trend. One challenge is keeping the transmittance while pixel density increases. Chiral Polymer Stabilized Vertical Alignment (C-PS-VA) technology uses LC mixtures with higher birefringence and a chiral dopant and increases transmittance by more than 10% compared to conventional Polymer Stabilized Vertical Alignment (PS-VA). This paper summarizes the recent developments of liquid crystal mixtures for C-PS-VA.
