  • Patent number: 10324559
    Abstract: A display device unit includes a plurality of image display panels in such a manner that display surfaces of the plurality of image display panels are orderly arranged on a flat surface, and is configured to display an image using the plurality of display surfaces as a single screen. The image display panel includes a drive electrode unit to which an application voltage is applied and a detection electrode unit at which a detection voltage is generated in accordance with the application voltage. The application voltage is applied solely to the drive electrode unit included in an application image display panel which is a part of the image display panels.
