Integrated test system for a touch sensor
In one embodiment, a method includes restricting current flow between a node of a touch sensor and each of a drive system of the touch sensor, a sense system of the touch sensor, and a test system of the touch sensor. The method further includes capacitively coupling the drive system to the sense sy...

| Zusammenfassung: | In one embodiment, a method includes restricting current flow between a node of a touch sensor and each of a drive system of the touch sensor, a sense system of the touch sensor, and a test system of the touch sensor. The method further includes capacitively coupling the drive system to the sense system through the test system. The method further includes using at least the drive system and the test system, inducing a charge on the sense system. The method further includes measuring the induced charge on the sense system. The method further includes making a pass or fail determination for at least a portion of the touch sensor based at least in part on the measured induced charge. |
