Abstract
An exemplary double-sided liquid crystal display includes a light guide plate, illuminators, a first liquid crystal panel, and a second liquid crystal panel. The light guide plate includes a first light emitting surface and a second light emitting surface. The first and second light emitting surfaces are configured for light emission. The illuminators are configured for providing light beams for the light guide plate. The first liquid crystal panel is configured for receiving the light beams from the first light emitting surface. The second liquid crystal panel is configured for receiving the light beams from the second light emitting surface. When the first liquid crystal panel is configured to display, the first liquid crystal panel is illuminated by only part of the illuminators. When the second liquid crystal panel is configured to display, the second liquid crystal panel is illuminated by all the illuminators.
