Abstract
A liquid crystal display and a driving method thereof are provided. The liquid crystal display includes a backlight source, a lower substrate at a light exit side of the backlight source, an upper substrate opposite to the lower substrate, and a liquid crystal layer between the two substrates. The backlight source includes a plurality of light sources, and light emitted from each light source is collimated light. The liquid crystal display further includes at least one first electrode and at least one second electrode between the lower substrate and the liquid crystal layer and a light shielding structure, orthographic projections of the light source and the light shielding structure on the lower substrate overlapping. The first and second electrodes are configured to receive different voltages to form an electric field, so that liquid crystal molecules within the electric field are deflected to form convex lens structures.
