In a display system, a second display device is disposed adjacent to a first display device. The first display device includes a first touch detection region adjacent to the second display device. The second display device includes a second touch detection region. A first frame period of the first display device includes a first display period for which the first display device displays an image and a first touch detection period for which a first touch detection circuit performs touch detection in a first touch detection region. A second frame period of the second display device includes a second display period for which the second display device displays an image and a second touch detection period for which a second touch detection circuit performs touch detection in a second touch detection region. Start and end timings of a first touch detection period overlap with a second display period.
