Abstract:
1. A foldable display device, comprising: a first body configured to support a first display screen; a second body configured to support a second display screen, wherein the first display screen and the second display screen are provided at a first side of the foldable display device; an angle sensing unit configured to sense a folding angle between the first body and the second body, wherein the first body and the second body are foldable in a direction to which the first display screen and the second display screen are facing; a first illuminance sensing unit provided in the first side configured to sense illuminance; a second illuminance sensing unit provided in the second side, which is an opposite side of the first side, configured to sense illuminance; and a processor configured to control the first body, the second body, the angle sensing unit, the first illuminance sensing unit, and the second illuminance sensing unit, wherein the processor is further configured to: set illuminance of the first display screen, the second display screen, or any combination thereof provided at the first side, based on a first illuminance value detected by the first illuminance sensing unit of the first side, when the folding angle between the first body and the second body is equal to an illuminance threshold angle or greater than the illuminance threshold angle, set the illuminance of the first display screen, the second display screen, or any combination thereof provided at the first side, based on a second illuminance value detected by the second illuminance sensing unit of the second side, when the folding angle between the first body and the second body is smaller than the illuminance threshold angle.
