The display apparatus includes a light-transmitting substrate, a backlight source, a liquid crystal layer and a grate-like structure. The liquid crystal layer is disposed between the light-transmitting substrate and the backlight source. The grate-like structure is disposed on a side of the light-transmitting substrate proximal to the liquid crystal layer. The grate-like structure is reused as both an electrode configured to control an equivalent refractive index of the liquid crystal layer and a grating. The backlight source includes a light guide plate and a collimated light source which is disposed on a side of the light guide plate. The grate-like structure is disposed on a side of the liquid crystal layer distal from the light guide plate and reused as both an electrode configured to control the refractive index of the liquid crystal and a grating."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Display apparatus and control method thereof, and display device","description":"Disclosed are a display apparatus and a control method thereof.
