The gradient profile of the liquid crystals molecules that causes the gradient profile of the refractive index is achieved by inducing non-uniformly distributed anchoring energy and an external electric or magnetic field applied to the liquid crystal layer. Unlike existing electrically controlled liquid crystal lens, the external electric or magnetic field has a uniform spatial distribution within the liquid crystal layer. The focal length of the liquid crystal lens is controlled via the non-uniformly distributed anchoring energy and by varying the uniformly distributed electric or magnetic field."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Low voltage liquid crystal lens with variable focal length","description":"Disclosed herein is a liquid crystal lens with a variable focal length.
