Abstract: Display device and driving method thereof are provided. The display device includes a housing, a display screen, and a drive circuit. The housing includes a first side and a second side opposite to the first side in a first direction. The display screen includes a first end and a second end. At least one of the first end and the second end is accommodated in the housing. A first display area in a display area of the display screen is located between the first side and the second side. A second display area in the display area of the display screen is accommodated in the housing. The drive circuit is configured, when the display screen displays an image, to provide drive signals to the first display area, and control a display of the first display area without providing the drive signals to the second display area.
