Abstract
A novel capacitive touch system includes a first controller having a plurality of channels, a first sensor row having a first discrete sensor element and a second discrete sensor element, a second sensor row having a first discrete sensor element and a second discrete sensor element, a first sensor column, a second sensor column, and a first signal line electrically coupling one of the plurality of channels of the controller to both the first and second discrete sensor elements of the first sensor row. In a particular embodiment, the first controller includes a second channel electrically connected to both the first and second discrete sensor elements of the second sensor row. In another particular embodiment, the capacitive touch system includes a second controller having a plurality of channels, the first sensor column includes a first discrete sensor element and a second discrete sensor element, and a first channel of the second controller is electrically coupled to both the first and second discrete sensor elements of the first sensor column.
