the disclosure relates to a touch sensing device and method . an embodiment of the disclosed method includes starting to count with a counter while charging a sensing point which has distributed capacitance periodically , then transferring the charge on the sensing point to a second capacitor . next , the voltage on the second capacitor is compared with a reference voltage , and if the former exceeds the latter , the counter stops counting and saving the value . if the voltage on the second capacitor is less than the reference voltage , the sensing point is judged to determine whether it is in touching state or in non - touching state according to the saved count value while discharging the second capacitor , clearing the counter after the discharge , then restarting the method . using the device and method of this disclosure , the touching sensing action can be tested accurately .
