    Abstract: A light guide plate is disclosed, including a plurality of light-adjusting panels disposed on or over a light-emitting side of the light guide plate. The plurality of light-adjusting panels are arranged in an array with a gap arranged between every two adjacent light-adjusting panels, and are configured to be controllable in a transparent state or in an opaque state to thereby realize a switch between a large divergence angle or a small divergence angle. Each light-adjusting panel includes oppositely disposed first electrode and second electrode, and a light adjusting layer disposed therebetween. The light adjusting layer is configured to be in an opaque state or in a transparent state depending on whether there is an electric field between the first electrode and the second electrode. A backlight assembly and a display apparatus containing the light guide plate, as well as a control method thereof, are also disclosed.
