Abstract
Embodiments of the invention generally provide an input device having a reduced system complexity and low production cost. As the size of input devices, such as touch pads and other similar devices increase, the need for an input device that is able to maintain or even improve the touch sensing accuracy without greatly increasing the manufacturing cost becomes increasingly important. Embodiments of the invention may provide an input device that includes an array of capacitive sensing pixels that each include a unique pair of sensor electrodes, wherein at least one of the electrodes in a first pixel is also in communication with another sensor electrode in at least one other pixel, which is not in the same row or column with the first pixel.
