Detecting apparatus and display apparatus

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.

Display device unit, control device, and image display panel

In a display apparatus, a touch panel where driving and sensing electrodes face each other across a dielectric substance outputs a detection signal from the sensing electrode in synchronization with a driving signal applied to the driving electrode. A pointing device points to a position on a touch surface of the touch panel. A detection assisting device includes an inverting circuit for obtaining a detection driving signal corresponding to the driving signal and inverting the phase thereof to generate an inversion signal, and outputs the inversion signal to the sensing electrode via the pointing device. A control device applies the driving signal to the driving electrode, obtains the detection signal generated at the sensing electrode according to the mutual capacitance between the driving and sensing electrodes and the inversion signal, and detects the pointing device in contact with or proximity to the touch panel based on the detection signal.
