Abstract:
1. A display device with touch detection, comprising: display elements; a plurality of common drive electrodes arranged in parallel to extend in one direction; a plurality of detection electrodes arranged in parallel to extend in a direction which intersects the common drive electrodes and allowing electrostatic capacitance to be formed at each intersection; a scan driving unit performing a first scan drive and a second scan drive, the first scan drive allowing a display drive signal for driving the display elements to be time-divisionally applied to each of the plurality of common drive electrodes in succession, the second scan drive allowing a touch detection drive signal for detecting an external proximity object to be time-divisionally applied to each of the plurality of common drive electrodes in succession; and a detection circuit detecting the external proximity object based on a touch detection signal which is outputted from the detection electrode in response to application of the touch detection drive signal or the display drive signal, wherein the scan driving unit is configured to, the detection circuit is configured to,
