摘要
Abstract
The high birefringence liquid crystals have important applications in LCD,but they are in-stable under UV exposure due to the conj ugated unsaturated structures.The ultraviolet stability of high birefringence liquid crystals was studied in this paper.First,several different additives were add-ed to the liquid crystal mixture A,such as triphenylphosphine oxide,4’-propylbi(cyclohexane)-4-formaldehyde,4-propyl-4’-cyclopentyl-3,5-difluorobiphenyl and UV-P.The liquid crystal mixtures were poured into TN-7.0-R test cells after stirred uniformly,then the test cells were exposed to ultra-violet,finally the liquid crystal parameters were tested.The results show that the UV stability of liq-uid crystal A can be significantly improved by UV-P,because the UV absorption of UV-P is most sim-ilar with liquid crystal A.关键词
