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.

Abstract: An image display apparatus includes a display panel that displays an image and a switching panel operated in a two-dimensional mode or three-dimensional mode such that the image is perceived as a two-dimensional mode or three-dimensional image on the display panel. The switching panel includes a plurality of unit devices. Each of the unit devices includes a first zone disposed at one side of a center axis of the unit device and a second zone disposed at the other side of the center axis. Each of the first zone and the second zone includes a plurality of electrodes, respectively. The plurality of electrodes do not overlap the center axis.
