Abstract: A display device and a method of driving a display device. The display device includes a housing, a display touch module including a non-exposed area covered by the housing, an exposed area located outside the housing, and an active area over the non-exposed area and the exposed area. The display touch module includes a display member configured to display an image and a touch member on the display member configured to sense a touch input. The display device also includes a boundary determining member configured to sense a capacitance of the touch member and calculate coordinates of an exposure boundary between the exposed area and non-exposed area of the display touch module. The display device is configured to adjust a display range of the active area according to the coordinates of the exposure boundary calculated by the boundary determining member.
