1. A detection method for enhanced 3D detection module, comprising steps of:

  • providing a pressure scanning pulse to an independent pressure-sensitive unit and at least one adjacent pressure-sensitive unit at a same time;

    respectively generating a first resistance variation and a second resistance variation from the independent pressure-sensitive unit and the at least one adjacent pressure-sensitive unit when the independent pressure-sensitive unit and the at least one adjacent pressure-sensitive unit are deformed by a pressing force from a touched point;

    generating a first pressure signal by the independent pressure-sensitive unit and a second pressure signal by the at least one adjacent pressure-sensitive unit in response to the pressure scanning pulse at the same time, wherein the first pressure signal includes the first resistance variation and the second pressure signal includes the second resistance variation;

    superimposing the first resistance variation and the second resistance variation to generate a superimposed pressure signal; and

    determining a pressing force value of the pressing force from the touched point according to the superimposed pressure signal.
