【 摘 要 】

Based on the elastic theory and the dynamics equation of liquid crystal, we use Finite-Difference iterative method to calculate the liquid crystal molecules director distributions under the effect of electric field. According to the director distributions, this paper gets the relationship between LCD modulation phase and the driving voltage. The results of simulation proves that with driving voltage varying from 0 to 5v and the crystal modulation phase varies from 0 to 4π.
