MUTUAL CAPACITANCE TOUCH SENSING DEVICE |
摘要 |
A mutual capacitive touch sensing device is disclosed. The touch sensing device includes a mutual capacitive sensing controller having a plurality of distinct drive lines and a plurality of distinct sense lines; a source for driving a current or voltage separately though each drive line; and a mutual capacitance sensing circuit that monitors the capacitance at the sensing lines. The touch sensing device also includes a plurality of independent and spatially distinct mutual capacitive sensing nodes set up in a non two dimensional array. Each node includes a drive electrode that is spatially separated from a sense electrode. The drive electrode is coupled to one of the drive lines and the sense electrode is coupled to one of the sense lines. Each node is set up with a different combination of drive and sense line coupled thereto. |
