Abstract:
A method of determining a touch event in a touch detection system includes transmitting at least one driving signal to a touch panel of the touch detection system; receiving a sensing signal corresponding to the driving signal from the touch panel; determining whether the touch event occurs by performing an initial digital operation on the sensing signal; determining whether the sensing signal is interfered with by a noise signal; and performing an entire determination on the sensing signal when the touch event is determined to occur or the sensing signal is determined to be interfered with by the noise signal.
