Abstract
A controller for position detection is disclosed. At least one first 1-D position corresponding to at least one external object is determined based on signals of a plurality of first sensors by self-capacitance detection. Then, at least one second 1-D position corresponding to the at least one first 1-D position is determined based on signals of a plurality of second sensors by mutual-capacitance detection.
