摘要
A display device includes a sensor, a display panel, and a plurality of electrodes for a touch sensor. The plurality of electrodes include drive electrodes and detection electrodes. The drive electrodes are also used as common electrodes for display, which are provided in the display panel. An image display operation of the display panel and a driving operation of the electrodes for the touch sensor are performed in a time sharing manner. In the driving operation of the electrodes for the touch sensor, a code division multiplexing (CDM) drive is performed in units of successive common electrodes, and a drive signal which synchronizes with the CDM drive is input to all common electrodes other than successive common electrodes subjected to the CDM drive.
