Abstract
An apparatus includes a touch screen panel including a sensing matrix arranged in a row-column format. The apparatus also includes a control device to scan the sensing matrix to detect a presence of multiple objects at least proximate to the touch screen panel. The control device can identify rows and columns of the sensing matrix that correspond to the presence of the multiple objects. The control device can orthogonally multiplex the identified rows and columns into one or more row-column pairs. The control device can scan at least one of the row-column pairs to detect locations of the multiple objects relative to the touch screen panel.
