Sensing apparatus for touch and force sensing

A touch and force sensing apparatus comprising:

• a touch electrode layer comprising a plurality of first touch electrodes arranged along a first direction and a plurality of second touch electrodes arranged along second direction, wherein the first direction is substantially perpendicular to the second direction;
• a protection layer arranged on a side of the touch electrode layer;
• a force electrode layer arranged on a side of the touch electrode layer, the side being opposite to the protection layer, the force electrode layer comprising at least one force sensing electrode;
• a resilient dielectric layer, arranged on a side of the force electrode layer, the side being opposite to the touch electrode layer;
• and
• a capacitance sensing module sequentially or randomly applying 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 a touch sensing operation;
• the capacitance sensing module sequentially or randomly applying a force capacitance-exciting signal to the at least one force sensing electrode, and receiving a force sensing signal from the force sensing electrode in a force sensing operation.
