摘要： 负性液晶MBBA在液晶盒中垂面排列,沿面外加电场后产生挠曲电效应.基于液晶弹性理论研究这一效应,基于变分理论得到了液晶指向矢满足的微分方程及边界条件.应用差分迭代方法进行了数值求解.在小角度近似下,得到了指向矢分布的解析解,与数值解和专著结果进行了比较.
关键词: 挠曲电效应, 负性液晶, 弱锚泊, 差分迭代方法
Abstract: Negative liquid crystal MBBA that aligns along the normal to the plates in liquid crystal cell will arise the flexoelectric effect when a external electric field is applied in the plane of slab.Based on the elastic theory of liquid crystal and variation theory, the effect is studied, and the differential equation and boundary condition about the director of liquid crystal have heen obtained.Finite-difference iterative method is used for numerical solution. Under the approximation of small angle, analytical solution of the distribution of the director has been also obtained, and compared with the numerical solution and the result of book.
Key words: flexoelectric effect, negative liquid crystal, weak anchoring, finite-difference iterative method
