Controller for position detection
First Claim
Patent Images
1. A controller for position detection, performing at least the following operations:
- determining at least one first 1-D position corresponding to at least one external object based on signals of a plurality of first sensors by self-capacitance detection, wherein each first 1-D position is determined based on a differential sensing information whose each value is a difference between signals of two 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 a plurality of second sensors by mutual-capacitance detection.

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. Each first 1-D position is determined based on a differential sensing information whose each value is based on signals of two 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.
