Abstract: A method for hybrid touch sensing for detecting a normal touch and a force touch concurrently is provided. The method includes the following steps. Provide a first driving signal to a first capacitor, wherein the first driving signal is a periodic signal with a first frequency. Provide a second driving signal to a second capacitor, wherein the second driving signal is a periodic signal with a second frequency different from the first frequency. Generate a composite sensing signal by feeding the first driving signal and the second driving signal to a front-end circuit. Extract information from the composite sensing signal to calculate a first change in capacitance of the first capacitor and a second change in capacitance of the second capacitor to detect the normal touch and the force touch concurrently.
