  • Detection method for enhanced 3D detection module
    Patent number: 10318037
    Abstract: A detection method for enhanced 3D detection module includes a plurality of touch units configured to sense positions of touch points, a plurality of pressure-sensitive units configured to sense pressing forces and a signal processing circuit, the detection method including: providing a touch scanning pulse to the plurality of touch units and providing a pressure scanning pulse to at least two of the pressure-sensitive units; generating touch signals by the plurality of touch units in response to the touch scanning pulse sensing the positions of the touch points and generating a superimposed pressure signal by the at least two of the pressure-sensitive units in response to the pressure scanning pulse sensing the pressing forces; and determining a position and a pressing force value of at least one touch point by the signal processing circuit according to the superimposed pressure signal and the touch signals.
