Abstract
Embodiments of the present disclosure provide a force detection apparatus and method, a touch device and an electronic terminal. The apparatus includes: a first detection capacitor, and a second detection capacitor configured to perform differential processing for a capacitance of the first detection capacitor to cancel an interference signal; wherein the first detection capacitor includes a force detection electrode, and the second detection capacitor includes a reference detection electrode, the force detection electrode and the reference detection electrode being arranged within a surface, such that the first detection capacitor and the second detection capacitor are simultaneously coupled to the interference signal causing interference to force detection, and differential processing is performed for capacitances of the first detection capacitor and the second detection capacitor. In this way, the interference signal, for example, which caused by a display device, is canceled, and sensitivity of force detection is enhanced while temperature drift is inhibited.
