Abstract

In this paper, a three-dimensional relaxation method and a finite difference method (FDM) are used to model the dynamic response behavior of liquid crystal (LC) microlens. Simulations have been done for the focus-swing patterned electrodes structures. The formation of disclination lines in the director orientation can be accurately predicted. Based on the simulation, a careful choice of the device structure and the voltage will help to design better lens. We can expect that the model developed by us can be utilized to design more complex LC microlens or other functioned LC structure.
