Input device

An input device comprising:

• a plurality of X scan electrodes extending in a Y direction to be arranged with intervals in an X direction perpendicular to the Y direction;
• a plurality of Y scan electrodes extending in the X direction to be arranged with intervals in the Y direction and insulated from the X scan electrodes;
• detection electrodes forming electrostatic capacitance with the X scan electrodes and the Y scan electrodes;
• an X driver supplying a pulsed driving signal to the X scan electrodes;
• a Y driver supplying a pulsed driving signal to the Y scan electrodes;
• and
• a detection unit detecting scan electrodes to be approached by a control object from detection signals to be obtained from the detection electrodes and the timing at which the driving signals are supplied to the X scan electrodes and the Y scan electrodes,
• wherein the driving signal that is supplied from the X driver to the X scan electrodes and the driving signal that is supplied from the Y driver to the Y scan electrodes are opposite in the timing of rising and falling of the pulses, and at the same scan time, one X scan electrode and one Y scan electrode are selected simultaneously and the driving signals are supplied to the selected X and Y scan electrodes, and
• wherein a predetermined number of repetitions of scan time be one cycle, and, in a first cycle, the same Y scan electrode is selected in all of the scan time and different X scan electrodes are selected at the respective scan time, and in a second cycle, a Y scan electrode different from the Y scan electrode in the first cycle is selected in all of the scan time and different X scan electrodes are selected at the respective scan time, and
• the cycles where different Y scan electrodes are selected are repeated a predetermined number of times.
