LIQUID CRYSTAL LENS, A LIQUID CRYSTAL MODULE HAVING THE LIQUID CRYSTAL LENS AND A METHOD OF DRIVING THE LIQUID CRYSTAL MODULE

摘要

A liquid crystal lens includes a plurality of first sub liquid crystal portions having refractive indexes varied based on voltages applied thereto, a plurality of second sub liquid crystal portions having refractive indexes varied based on voltages applied thereto, where the second sub liquid crystal portions are adjacent to the first sub liquid crystal portions, respectively and a controller which controls the voltages applied to the first sub liquid crystal portions and the voltage applied to the second sub liquid crystal portions to provide a lens part.
