| description | The invention provides a touch control sensing device including a plurality of pins, a logic control module, a drivesensing control module, a noise suppressing module and an analogdigital converting module. The drivesensing control module defines a drive pin and a sensing pin of the pins according to signals of the drivesensing control module. The drive pin and the sensing pin are coupled to a drive line and a sensing line of a conducting film sensor respectively. The noise suppressing module is composed of an exchange capacitance amplifier and is used for detecting the coupling capacitance among different nodes between the drive line and the sensing line according to noise suppressing control signals, and excluding the capacitance between the drive line and a grounding terminal as well as the sensing line and the grounding terminal. The analogdigital converting module converts analog data processed by the noise suppressing module into digital data and outputs the digital data to the logic control module. |
