The transparent substrate is disposed over the viewing surface. Each light source is disposed over a side surface of the transparent substrate and is configured to emit a light into the transparent substrate from the side surface upon being turned on. The transparent substrate is provided with a plurality of dots, which are configured to scatter the light from each light source such that the viewing angle over the viewing surface is switched by turning on or off the each light source. A display apparatus including a viewing angle control device is also disclosed, where the transparent substrate of the viewing angle control device is disposed over a display surface of a display panel."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Viewing angle control device and display apparatus","description":"A viewing angle control device capable of controlling a viewing angle over a viewing surface is disclosed herein, which includes a transparent substrate and at least one light source.
