Abstract
A detection apparatus includes a substrate, a plurality of first electrodes provided on the substrate, a first selection circuit provided on the substrate, the first selection circuit including a plurality of first input terminals that receive a first control signal supplied from an outside and a plurality of first output terminals that output a first selection signal based on the first control signal, and a second selection circuit provided on the substrate, the second selection circuit including a plurality of second input terminals that receive a second control signal supplied from the outside and a plurality of second output terminals that output a second selection signal based on the second control signal.
Claims19
A detection apparatus comprising:
- a substrate;
- a plurality of first electrodes provided on the substrate;
- a first selection circuit provided on the substrate, the first selection circuit including a plurality of first input terminals that receive a first control signal supplied from an outside and a plurality of first output terminals that output a first selection signal based on the first control signal;
- and
- a second selection circuit provided on the substrate, the second selection circuit including a plurality of second input terminals that receive a second control signal supplied from the outside and a plurality of second output terminals that output a second selection signal based on the second control signal, wherein
- the first electrodes are supplied with a drive signal having a phase determined based on the first selection signal and the second selection signal, and
- N≤P×Q is satisfied where N is number of the first electrodes, P is number of the first output terminals, and Q is number of the second output terminals.
A detection apparatus comprising:
- a substrate;
- a plurality of first electrodes provided on the substrate;
- drive signal supply lines coupled to the first electrodes and configured to supply a drive signal to the first electrodes respectively;
- a first selection circuit provided on the substrate and configured to provide a plurality of first selection signals;
- a plurality of first selection signal lines configured to output the first selection signals individually from the first selection circuit;
- a second selection circuit provided on the substrate and configured to provide a plurality of second selection signals;
- a plurality of second selection signal lines configured to output the second selection signals individually from the second selection circuit;
- and
- a plurality of third selection circuits provided on the substrate and coupled to drive signal supply line blocks respectively, the drive signal supply line blocks each including some of the drive signal supply lines, wherein
- one of the third selection circuits is coupled to the plurality of the first selection signal lines and one of the second selection signal lines and provide the drive signal based on the first selection signals and one of the second selection signals.
