Abstract: An electronic device includes a display device including a display panel, a touch panel, and a touch sensing circuit configured to sense a touch input. The electronic device also includes an input pen configured to provide, to the touch sensing circuit, information on intensity of pressure applied to the display device. The touch panel includes touch pressure sensors and signal lines connected to the touch pressure sensors. Each touch pressure sensor has an area per unit length that increases along an extended direction of each touch pressure sensor. Each touch pressure sensor has a resistance that varies with an intensity of pressure and an area of pressure applied to the touch pressure sensors.

Abstract: A flexible display device includes a bendable touch display panel, a touch detector, a screen divider, and a panel driver. The touch display panel includes at least one touch sensor. The touch detector detects a curved portion of the touch display panel and touch information corresponding to a touch applied to the touch display panel based on a sensing result from the at least one touch sensor. The screen divider divides a display area of the touch display panel into a plurality of divided areas with respect to the curved portion, and defines the divided areas as a display divided area and a non-display divided area, respectively, based on the touch information. The panel driver activates at least a portion of the display divided area and deactivate the non-display divided area.

Abstract: A flexible display device includes a flexible display panel to generate an image and a bending detection screen to detect a bending angle and a bending position. The bending detection screen includes an angle detection sensor and a position detection sensor. The angle detection sensor includes a material with a resistance that changes in correspondence to an intensity of an applied stress. The angle detection sensor has an area per unit length that is substantially constant on a base surface. The position detection sensor includes a material with a resistance that changes in correspondence to an intensity of the applied stress. The position detection sensor has an area per unit length that increases along a length direction on the base surface. Signal lines are connected to the angle and position detection sensors.
