Abstract:
1. A method for position detection that neglects wide-area touches, 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; obtaining a first 1-D sensing information from signals of the first sensors by self-capacitance detection; obtaining a second 1-D sensing information from signals of the second sensors by self-capacitance detection; determining a detected touch related sensing information based on the range of each touch related sensing information on the first 1-D sensing information and the second 1-D sensing information, wherein each touch related sensing information corresponds to a touch or approach by at least one external object; analyzing at least one 1-D position based on each detected touch related sensing information; and analyzing at least one 2-D position by performing mutual-capacitance detection on each 1-D position.
