Capacitive touch detection system and detection signal receiving and waveform shaping module |
摘要 |
An exemplary capacitive touch detection system includes a capacitive touch panel and a detection control circuit. The capacitive touch panel includes a plurality of input terminals and output terminals. The detection control circuit includes a scanning signal transmitting module electrically coupled to the input terminals and a detection signal receiving and waveform shaping module including a receiver and an impedance-matching network. The detection signal receiving and waveform shaping module is electrically coupled to the output terminals for receiving and processing a plurality of detection signals outputted from the respective output terminals and thereby producing a plurality of processed detection signals. The receiver is used for receiving the detection signals. The impedance-matching network is used for performing a waveform shaping operation applied to the detection signals to compensate an effect caused by uneven RC loading distribution in the capacitive touch panel and thereby producing the processed detection signals. |
