Abstract
Detection device is provided and includes first and second electrodes disposed facing or close to first electrodes; first drive circuit configured to supply first drive signal; second driver circuit configured to supply second drive signal; and detector configured to detect detection signal output from first electrodes, wherein detection device has first period in which detector detects first detection signal output from first electrodes in response to supply of second drive signal to second electrodes, if first detection signal detected in first period is equal to or higher than predetermined threshold, detector is configured to output an output signal including panel coordinates generated based on first detection signal, if first detection signal detected in first period is lower than predetermined threshold, detection device is transitioned to a second period in which detector detects second detection signal output from first electrodes in response to supply of first drive signal to first electrodes and supply of guard signal synchronized with first drive signal to second electrodes, and detector is configured to output an output signal including panel coordinates generated based on second detection signal.
