摘要：【中文】本发明公开了一种弧形柱状空腔与电极的可变焦液晶透镜，主要包括保护壳、驱动模块、以及设置在保护壳内的上电极、下电极、液晶取向层和液晶。本发明在灌注液晶之后，可以使得里面的液晶分子按照均匀弧形柱状填充空间而均匀分布，之后通过取向作用使液晶分子按照实验研究所需要的方向进行取向排列，这样会使得在未加外电场的时候，液晶分子会有一定的偏转角度。如此以来，后续需要进行更大范围变焦时，液晶分子需要通过外加电压去转动更大的角度，在已有一定偏转角度液晶分子的基础上增加角度，会使所加的外部电场的电压会相对降低，也就是说相对平行板变焦液晶透镜而言，水平液晶分子转过相同度数需要施加的电压比本发明要大。 【EN】The invention discloses a variable-focus liquid crystal lens with an arc-shaped columnar cavity and electrodes, which mainly comprises a protective shell, a driving module, an upper electrode, a lower electrode, a liquid crystal orientation layer and liquid crystals, wherein the upper electrode, the lower electrode, the liquid crystal orientation layer and the liquid crystals are arranged in the protective shell. After liquid crystal is poured, liquid crystal molecules in the liquid crystal layer can be uniformly distributed according to the uniform arc-shaped columnar filling space, and then the liquid crystal molecules are aligned according to the direction required by experimental research through the alignment effect, so that the liquid crystal molecules have a certain deflection angle when an external electric field is not applied. Therefore, when a larger-range zooming is needed subsequently, the liquid crystal molecules need to rotate by a larger angle through an applied voltage, and the angle is increased on the basis of the existing liquid crystal molecules with a certain deflection angle, so that the voltage of an applied external electric field can be relatively reduced, namely, the voltage which needs to be applied when the horizontal liquid crystal molecules rotate by the same degree is larger than that of the parallel plate zooming liquid crystal lens.
