| Zusammenfassung: | Disclosed is a capacitance detection apparatus including a panel having a parasitic capacitor formed therein and including an electrode which forms a self-capacitor with an object, a compensation capacitor configured to share charges with the parasitic capacitor and the self-capacitor to output a detection signal with compensation for an influence of the parasitic capacitor, a switch unit including a plurality of switches which get turned on or off so that the compensation capacitor compensates for the influence of the parasitic capacitor, and an output voltage adjusting unit connected to the compensation capacitor and configured to adjust an output range of the detection signal output by the compensation capacitor. |
