Abstract
An integral apparatus for sensing touch and force includes a touch-control panel, a force electrode layer, a touch sensing integrated circuit, and a force sensing integrated circuit. In a touch sensing operation, a plurality of touch sensing electrodes of the touch-control panel are electrically connected to the touch sensing integrated circuit through a plurality of switch circuits in the force sensing integrated circuit to conduct the touch sensing operation. In a force sensing operation, the touch sensing electrodes are electrically connected to a capacitance sensing circuit in the force sensing integrated circuit through a plurality of switch circuits in the force sensing integrated circuit to conduct a force sensing operation.
