Abstract
A touch device integrated with capacitive and resistive sensing operation includes a first substrate on which a first electrode pattern is formed and a second substrate on which a second electrode pattern is formed. The first and second electrode patterns are respectively connected to a microprocessor via a first scanning circuit and a second scanning circuit. When a user slightly touches a touch operation surface of the touch device, the touch device is set in a capacitive touch position detection mode. When the user forcibly depresses the touch operation surface of the touch device or carries out a hand writing input operation on the touch operation surface of the touch device, the touch device is set in a resistive touch position detection mode.
