The liquid crystal lens includes a first substrate having a plurality of first electrodes, a second substrate disposed opposite to the first substrate and having a second electrode, a liquid crystal layer constituting liquid crystal molecules disposed between the first substrate and the second substrate, and a plurality spacers. The controller is configured to, when the display apparatus is in a 2D display state, control a first voltage between the first electrodes and the second electrode to generate a first electric field with an equal electric field intensity, which causes the liquid crystal molecules to rotate by a predetermined degree such that a refractive index difference between the liquid crystal molecules and the spacers is within a preset range."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"2D/3D switchable stereoscopic display apparatus","description":"A 2D/3D switchable stereoscopic display apparatus includes a display panel, a liquid crystal lens, and a controller.
