Abstract
A detection apparatus includes a substrate, a plurality of first electrodes provided on the substrate, and a first electrode selection circuit provided on the substrate and including a first selection circuit configured to provide a first selection signal having a phase determined for each of the plurality of first electrodes and a second selection circuit configured to provide a second selection signal having a phase determined for each of first electrode blocks including the plurality of first electrodes.
Claims20
A detection apparatus comprising:
- a substrate;
- a plurality of first electrodes provided on the substrate;
- and
- a first electrode selection circuit provided on the substrate and including a first selection circuit configured to provide a first selection signal having a phase determined for each of the plurality of first electrodes and a second selection circuit configured to provide a second selection signal having a phase determined for each of first electrode blocks including the plurality of first electrodes, wherein
- the first electrode selection circuit has
- a first detection mode of supplying same signal of the first drive signal to each of the first electrode blocks in a time-division manner based on the first selection signal and the second selection signal, and
- the first electrode selection circuit has a second detection mode of supplying, to the plurality of first electrodes, a second drive signal having a phase determined for each of the plurality of first electrodes based on the first selection signal and the second selection signal.
