| Zusammenfassung: | According to an embodiment of the present invention, a capacitance detecting apparatus includes a signal source for providing a driving signal, a capacitance detecting panel for receiving the driving signal and providing a capacitance detection signal formed by the driving signal and a noise signal formed by receiving a noise, and a detection circuit unit for receiving the capacitance detection signal and the noise signal, removing the influence of the noise signal from the capacitance detection signal and outputting the signal without the influence of the noise signal. Accordingly, the present invention can obtain the signal without the influence of the noise signal.
