Touch panel device

A touch panel device comprising:

• a plurality of drive wiring lines extending in a column direction, each of the plurality of drive wiring lines configured to cause a drive signal to flow;
• a plurality of detection wiring lines extending in a row direction intersecting the plurality of drive wiring lines, each of the plurality of detection wiring lines configured to cause a detection signal to flow, the detection signal indicating a change in a capacitance formed based on the corresponding drive wiring line among the plurality of drive wiring lines;
• a plurality of drive electrodes individually connected to the corresponding drive wiring line among the plurality of drive wiring lines;
• a plurality of detection electrodes individually connected to the corresponding detection wiring line among the plurality of detection wiring lines;
• and
• a switching unit configured to switch a connection state of each two of the plurality of drive wiring lines, wherein
• the plurality of drive wiring lines include a plurality of first drive wiring lines and a plurality of second drive wiring lines alternately arranged,
• the plurality of drive electrodes are alternately connected to the plurality of first drive wiring lines and the plurality of second drive wiring lines adjacent to each other for every first predetermined constant number of the drive electrodes along a column direction, and
• the switching unit is configured to switch between
• a first connection state in which the first drive wiring line and the second drive wiring line that are adjacent to each other among the plurality of drive wiring lines are connected, and
• a second connection state in which the first drive wiring lines adjacent to each other are connected to each other and the second drive wiring lines adjacent to each other are connected to each other.
