ABSTRACT
Chiral dopant plays an important role in TN model. To investigate how chiral dopant adjusts performance of TN model, two liquid crystal mixtures which were made of different liquid crystal system were chosen as hosts, and then two series of chiral-nematic liquid crystal mixtures which contain different concentration of chiral dopant were obtained. The alignment of LCs in cells was investigated and explained theoretically from the view of elastic constants K. It indicates that chiral dopant affect the alignment behavior of LCs. The concentration of chiral dopant is proportional to threshold voltage and steepness. However, the concentration of chiral dopant is inversely proportional to contrast ratio. The research of chiral dopant could make the LCs match the integrated circuit (IC) better, which contribute to a higher contrast ratio and make the display more clear, detailed and realistic.
