Minimal driving of transmitters to increase hover detection

A touch sensor is provided with different operational modes. One mode may be the operation of the touch sensor with a reduced set of transmitting rows than another mode. Transmitting on a reduced set of rows from the normal set of transmitting rows provides an operational mode that is able to detect...

Zusammenfassung:A touch sensor is provided with different operational modes. One mode may be the operation of the touch sensor with a reduced set of transmitting rows than another mode. Transmitting on a reduced set of rows from the normal set of transmitting rows provides an operational mode that is able to detect touch events at greater distances from the touch surface than when a full set of transmitting rows is being driven.
