Abstract

In this paper, a three-dimensional relaxation method together with a finite difference method (FDM) are used to model the dynamic response behavior of liquid crystal (LC) directors filled into a cavity with complex patterned electrodes. Simulations and analysis have been done for the focus-swing patterned electrodes structures. A new type of LC micro-structure which has an ability to swing its focus over its focal plane has been designed. The simulation shows that the new LC structure designed by us has also a strong ability of swing focus over focal plane. We can expect that the model developed by us can be utilized to design more complex LC microlenses or other functioned LC structures.
