Abstract: A display device includes a pressure sensing element. The pressure sensing element senses a pressure input applied thereto from the outside, and the display device is controlled based on the sensed pressure input. The pressure sensing element includes a contact sensing area to sense the pressure input and a defect sensing area to sense a defect. The pressure sensing element measures a resistance value in the defect sensing area and identifies whether at least one of lines of the pressure sensing element is disconnected.

Abstract: A touch panel includes a substrate, detection electrodes, and connection electrodes. The substrate includes a planar surface portion and a curved surface portion adjacent to the planar surface portion in a first direction, the curved surface portion including an active region and another region disposed outside the active region. The detection electrodes are disposed on the substrate. The detection electrodes are arranged in the first direction and a second direction crossing the first direction. The connection electrodes electrically connect adjacent detection electrodes arranged in a same direction as one another. A connection electrode of the connection electrodes connecting detection electrodes adjacent to each other of the detection electrodes arranged in the first direction is disposed in the active region of the curved surface portion. The connection electrode includes a portion extending in a different direction than the first direction.

Abstract: An electronic device includes a window, a display module, a pressure sensor, and a bracket. The window includes a flat area and a curved area. The display module is disposed on a lower surface of the window to overlap with the flat area and the curved area. The pressure sensor is disposed on a lower surface of the display module to overlap with the curved area. The bracket is disposed on the lower surface of the display module and coupled to at least one of the window and the display module. The pressure sensor is disposed between the window and the bracket. The lower surface of the window and the lower surface of the display module face the same direction.
