Switchable Fresnel lens and fabrication method thereof

摘要

A switchable Fresnel lens and a fabrication method thereof are disclosed. The switchable Fresnel lens comprises: an upper plate having a first electrode; a lower plate having a second electrode; and a lens cell comprising a liquid crystal layer sealed between the upper plate and the lower plate. The lens cell comprises a Fresnel lens formed by an electric field applied through the first and second electrodes, and having a discontinuous boundary. The lens cell comprises barrier ribs that are vertically formed between the upper plate and the lower plate at the discontinuous boundary of the Fresnel lens.
