摘要:
A touch detection method for a touch control device including a touch panel includes examining whether a charging capacity for charging a measured capacitor of the touch panel and a discharging capacity for discharging the measured capacitor are determined; charging and discharging the measured capacitor by using the charging capacity and the discharging capacity when the charging capacity and the discharging capacity are determined and receiving a count value representing the capacitance of the measured capacitor, examining whether a base count value is set, calculating a difference between the count value and the base count value when the base count value is set, for determining whether the touch panel is touched, examining whether the count value is in a predetermined range, and performing a charging and discharging capacity setting process when the count value is out of the predetermined range, for adjusting the charging capacity and the discharging capacity.
