Abstract
A touch position detector includes a plurality of capacitance sensors, a negative capacitance compensation unit, an analog/digital converter and a micro processing unit. The negative capacitance compensation unit is utilized to compensate the capacitance of the capacitance sensor and get a capacitance change. The micro controller unit is utilized to detect the touch position according to the capacitance change. It is easy to get the touch position by using the touch position detector.
