    IPC: G06F3/041 ,  G09G5/00

    Abstract: A display device includes a display panel. A window is disposed on the display panel. A conductive sheet is disposed beneath the display panel such that the display panel is disposed between the window and the conductive sheet. A pressure sensor is disposed between the display panel and the conductive sheet. The pressure sensor includes a sensing area corresponding to a portion of the pressure sensor. A pressure concentration bump is disposed between the window and the conductive sheet. The pressure concentration bump overlaps the sensing area. The pressure sensor includes a first electrode disposed within the sensing area and a second electrode spaced apart from the first electrode.
