Abstract
A touch sensitive system includes a touch sensitive area. A plurality of spaced apart first electrodes are disposed in the touch sensitive area and extend continuously along a first direction. A plurality of spaced apart second electrodes are disposed in the touch sensitive area and extend continuously along a different second direction. A plurality of nodes are disposed in the touch sensitive area, each node being defined by corresponding first and second electrodes traversing each other at the node. The touch sensitive system detect a location of a touch applied proximate a node by detecting a change in a coupling capacitance between the corresponding first and second electrodes traversing each other at the node. Each first electrode traverses at least one, but not all, of the second electrodes, and each second electrode traverses at least one, but not all, of the first electrodes.
