摘要: Embodiments described herein provide capacitive sensing devices and methods. A substrate having a plurality of pairs of conductive traces formed thereon is provided. The pairs of conductive traces include first and second conductive traces having first and second opposing ends. A capacitance variation of a plurality of the first conductive traces and a plurality of the second conductive traces is measured. The capacitance variation of at least some of the second conductive traces is measured before the capacitance variation for all of the plurality of first conductive traces is measured. A position coordinate in a two-dimensional coordinate system on the capacitive sensing device is determined based on the measuring a capacitance variation of a plurality of the first conductive traces and a plurality of the second conductive traces.
