Integral sensing apparatus for touch and force sensing and method for the same

An integral sensing apparatus for touch and force sensing, the integral sensing apparatus comprising:

• a touch electrode layer having a plurality of first touch electrodes arranged along a first direction and a plurality of second touch electrodes arranged along a second direction substantially perpendicular to the first direction;
• 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;
• a capacitance sensing module electrically connected to the touch electrode layer and the force electrode layer;
• in touch sensing operation, the capacitance sensing module sequentially or randomly sending a touch driving signal to selected ones of the second touch electrodes, and sequentially or randomly receiving a touch sensing signal from selected ones of the first touch electrodes;
• in force sensing operation, the capacitance sensing module sending a force capacitance-exciting signal to the at least one force sensing electrode and obtains a force sensing signal from the force sensing electrode.
