Abstract:
A force-touch sensing apparatus with metal traces includes an upper substrate, a metal trace layer, a transparent touch-electrode layer, an insulating layer, a transparent force-electrode layer, a resilient dielectric material layer, and a capacitance sensing circuit. The capacitance sensing circuit sequentially or randomly applies a touch capacitance-exciting signal to a selected transparent touch sensing electrode and receives a touch sensing signal from the selected transparent touch sensing electrode for a touch sensing operation. The capacitance sensing circuit applies a force capacitance-exciting signal to the at least one transparent force sensing electrode, and sequentially or randomly applies a counter-exciting signal to the transparent touch sensing electrode and receives a force sensing signal from the at least one transparent force sensing electrode for a force sensing operation.
