Abstract:
According to an aspect, a display device with a touch detection function includes a controller, touch wiring that supplies a touch drive signal to drive electrodes, and a plurality of switch groups that are provided for each of the drive electrodes, each of the plurality of switch groups having selection switches. The plurality of switch groups select a drive electrode to be coupled to a touch wiring based on a selection signal from the controller. The selection switches for each of the plurality of switch groups are coupled in parallel with each other between a corresponding drive electrode and the touch wiring, and for each of the drive electrodes, all of the selection switches operate in accordance with the selection signal, couple the corresponding drive electrodes and the touch wiring, and apply the touch drive signal to the corresponding drive electrodes.
