Abstract
A method for driving an optical modulation device is provided. The optical modulation device includes first and second portions. Each of the first and second portions includes a first plate, a second plate opposite to the first plate, and a liquid crystal layer disposed between the first and second plates. The method includes forming a forward phase gradient in the first portion by applying a first driving signal to first and second electrodes in the first plate of the first portion and a third electrode in the second plate of the first portion. The method further includes forming a reverse phase gradient in the second portion by applying a second driving signal differing from the first driving signal to fourth and fifth electrodes in the first plate of the second portion and a sixth electrode in the second plate of the second portion.
