Abstract:
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 1-D position 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 corresponding to the at least one first 1-D position based on signals of these second sensors by mutual-capacitance detection, further comprising: determining at least one touch-related first sensor based on the at least one first 1-D position; and determining at least one touch-related second sensor based on the at least one second 1-D position, further comprising: when the number of the at least one touch-related second sensor is greater than the number of the at least one touch-related first sensor, providing at least one 2-D position based on the at least one second 1-D position corresponding to the at least one first 1-D position.
