Classification: CPC G  H | IPC G  H

Claim 1:
2. The display device according to claim 1, comprising a switching circuit configured to switch a connection destination of each of the divided second electrodes between a power supply circuit configured to supply a fixed potential for allowing the drive current to flow through the display element and a pseudo driving signal output circuit configured to supply a pseudo driving signal having a same phase and a same potential as the touch driving signal, wherein
during the current measurement period, the switching circuit connects a divided second electrode corresponding to a block to which sensor electrodes that are targets for application of the touch driving signal belong to the pseudo driving signal output circuit, and connects a divided second electrode corresponding to a block other than the block to which sensor electrodes that are targets for application of the touch driving signal belong to the power supply circuit.
