1. A method for position detection, comprising:

  • providing a sensing device including a plurality of sensors including a plurality of first sensors and a plurality of second sensors, these first and second sensors intersecting each other at a plurality of intersecting points;

    determining at least one first sensor corresponding to at least one external touch based on signals of these first sensors by self-capacitance detection; and

    determining at least one second 1-D position while each of the at least one determined first sensor is provided with a driving signal based on signals of these second sensors by mutual-capacitance detection.
