P‐265: <i>Late‐News Poster:</i> A Liquid Crystal Material with High Negative Dielectric Anisotropy for Improving Response Time

Response time is one of the most important parameters to evaluate an LCD panel. To achieve faster response in LCDs, better liquid crystal monomers are needed while other parameters remain unchanged. For this purpose, liquid crystal monomers with higher dielectric anisotropy and lower rotational viscosity are urgently required. Herein, in this work, we reported a new liquid crystal material, named DBDF, that possessed highly negative dielectric anisotropy and relatively low viscosity. Utilizing a proper ratio in the liquid crystal mixtures, DBDF could maintain high reliability and stability before and after UV irradiation. Furthermore, compared to normal liquid crystal materials, the addition of DBDF enabled a shorter response time when keeping other parameters the same. Overall, DBDF will be a good candidate to improve the response of liquid crystals.
