  • Patent number: 10809555
    Abstract: According to one embodiment, a force sensing device includes a first insulating layer, a first electrode layer on the first insulating layer, a second electrode layer provided in opposition to the first electrode layer, and an elastic layer held between one or both of the first insulating layer and the first electrode layer, and the second electrode layer, and configured to prevent the first and second electrode layers from coming into contact with each other even while allowing the first and second electrode layers to get close to each other. When the first electrode layer or the second electrode layer is pressed, the pressing force is sensed on the basis of a variation in the capacitance between the first electrode layer and the second electrode layer.

  • Patent number: 10725593
    Abstract: The display device includes: a cover glass including a screen that can be pressed; a liquid crystal panel arranged on a back side of the cover glass in a thickness direction (Z direction); a drive electrode arranged in a region corresponding to the screen in the liquid crystal panel; a base electrode arranged in the region corresponding to the screen at a position spaced apart from the drive electrode on the back side in the thickness direction; a cushion layer arranged between the liquid crystal panel and the base electrode; and a circuit that detects an electric signal representing the amount of change in capacitance between the drive electrode and the base electrode as a signal which enables calculation of a pressing force of the press. The cushion layer has such a characteristic that an elastic modulus decreases as approaching a periphery from a center in the region corresponding to the screen.
