Abstract
Hybrid force sensing includes acquiring absolute capacitance measurements of the absolute capacitance of at least one frame side electrode, acquiring mutual capacitance measurements of the mutual capacitance between the at least one frame side electrode and at least one display side electrode. Hybrid force sensing further includes determining an absolute capacitance derived force from the absolute capacitance measurements, determining a mutual capacitance derived force from the mutual capacitance measurements, and combining the absolute capacitance derived force and the mutual capacitance derived force to obtain a combined force. Hybrid force sensing further includes performing an action based on the combined force.
