Abstract
Aspects of the invention relate to a method and apparatus for scanning an array of sensors. More particularly, the invention is directed towards scanning an array of sensors to accurately determine actuated sensors on a contact-sensitive surface. In one embodiment, three sets of sensing lines can be incorporated into the sensing area for ghost-free detection of up to two keys. Further in other embodiments, n sets of sensing lines can be incorporated into the sensing area for ghost free detection of up to n−1 keys.
