Detection device, display device, and detection method

A display device, comprising:

• a display function layer that displays an image;
• at least one first electrode group that includes a plurality of first electrodes, the first electrode outputting a detection signal;
• and
• a selection driver configured to perform a first driving during a first period and a second driving during a second period which is different from the first period,
• wherein, the selection driver is configured to, during the first driving,
• select a plurality of first detection electrodes from the first electrode group according to a first selection signal;
• and
• output a plurality of first integrated signals, the first integrated signal being an integrated value of a plurality of first detection signals, and each of the first detection signals being output by the first detection electrodes on a one-to-one basis, and
• wherein, the selection driver is configured to, during the second driving,
• select a plurality of second detection electrodes from the first electrode group in accordance with a second selection signal, the second detection electrodes being different from the first detection electrodes, and the second selection signal being different from the first selection signal, and
• output a plurality of second integrated signals, the second integrated signal being an integrated value of a plurality of second detection signals, and each of the second detection signals being output by the second detection electrodes on a one-to-one basis.
