Classification: CPC G | IPC G

Claim 5:
6. The sensor device of claim 1, wherein
the panel further includes a third electrode provided on the second main surface side of the insulating layer,
the first electrode and the second electrode are located in a first area,
the third electrode is located in a second area outside the first area,
the first circuit further includes a second amplifier,
during the first sensing drive period,
the timing control circuit outputs a fifth synchronization signal generated based on the first synchronization signal and having a polarity inverted from the polarity of the first synchronization signal, and
the second amplifier amplifies the fifth synchronization signal and provides the amplified fifth synchronization signal to the third electrode, and

an amplitude of the fifth synchronization signal amplified by the second amplifier is greater than an amplitude of the second synchronization signal amplified by the first amplifier.
