Abstract
A detector circuit and detect method of a capacitive touch panel conditionally abort sensing of useless traces of the capacitive touch panel when the capacitive touch panel senses the traces thereof. For a selected trace, the trace voltage thereof is sampled to be compared with a threshold voltage. If the sampled voltage is lower than the threshold voltage, the sensing of this trace is aborted and thus the operation of the detector circuit is reduced to improve the performance of the capacitive touch panel.
