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.

Abstract: A display apparatus includes a display panel and a touch sensing unit disposed on the display panel. The touch sensing unit includes a touch sensor and a first pressure sensor. The touch sensor includes a first touch electrode layer and a second touch electrode layer disposed on the first touch electrode layer. The first pressure sensor includes: a transmission pressure electrode, a sensing pressure electrode separated from the transmission pressure electrode, and a piezoresistive pattern contacting each of the transmission pressure electrode and the sensing pressure electrode. Each of the transmission pressure electrode and the sensing pressure electrode is disposed in a same layer as any one of the first touch electrode layer and the second touch electrode layer.

Abstract: A display device includes a display element. The display device may include a touch substrate overlapping the display element and may overlap an external object when the external object provides a touch to the display device. The display device may include a first angle sensor disposed at a first corner of the touch substrate for determining a first touch angle related to the touch. The display device may include a second angle sensor disposed at a second corner of the touch substrate for determining a second touch angle related to the touch. The display device may include a force sensor disposed at the first corner of the touch substrate for determining a distance related to the touch. The display device may include a computation part configured to determine a touch coordinate associated with the touch based on the first touch angle, the second touch angle, and the distance.
