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.
