Problems solved by technology

However, as the dielectric anisotropy increases, the response time of the liquid crystal display becomes slower and slower, which affects the display effect. Specifically, the response formula of the liquid crystal display depends on the rotational viscosity of the liquid crystal. The lower the rotational viscosity, the faster the response time
