Abstract:
A sensing apparatus for touch and force sensing includes from, top to bottom, a protection layer, a touch electrode layer, a force electrode layer, and a resilient dielectric layer, and further includes a capacitance sensing module. In touch sensing operation, the capacitance sensing module sequentially or randomly applies 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 sequentially or randomly applies a force capacitance-exciting signal to the at least one force sensing electrode and obtains a force sensing signal from the force sensing electrode.
