Abstract:
An integral sensing apparatus for touch and force sensing includes a touch electrode layer having first touch electrodes and second touch electrodes arranged, a protection layer arranged on one side of the touch electrode layer, a force electrode layer having at least one force sensing electrode, a resilient dielectric layer arranged between the touch electrode layer and the force electrode layer, and a capacitance sensing module. In touch sensing operation, the capacitance sensing module sequentially or randomly sends a touch driving signal to selected ones of the second touch electrodes, and sequentially or randomly receives a touch sensing signal from selected ones of the first touch electrodes. In force sensing operation, the capacitance sensing module sends a force capacitance-exciting signal to the at least one force sensing electrode and obtains a force sensing signal from the force sensing electrode.
