In a 3D display mode, under control of an electric field, liquid crystal molecules of a first liquid crystal layer are deflected to form a plurality of first lenticular lens structures. In case of switching from the 3D display mode into a 2D display mode, under the control of an electric field, liquid crystal molecules in a second liquid crystal layer are deflected to form a plurality of second lenticular lens structures; the second lenticular lens structures are mirror symmetric to the corresponding first lenticular lens structures, so as to compensate a phase delay of a light modulated by the first lenticular lens structures, such that the light passes through the double-layered liquid crystal lens without deflection, and thus a normal 2D display state is realized."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Double-layered liquid crystal lens and 3D display apparatus","description":"A double-layered liquid crystal lens in which two liquid crystal layers are disposed, and a 3D display apparatus.
