Differential transmission is provided in a capacitive sensor for reducing cross-talk between rows and columns. A capacitive touch sensitive device as disclosed herein includes row conductors and column conductors, a first row signal generator for transmitting a first row signal on a first row conductor, a second row signal generator for transmitting a second row signal on a second row conductor, and a touch processor for identifying a touch event on the touch interface by processing signals present on at least one of the column conductors. The first and second row signals together form a differential row group of signals that cancel each other out or at least substantially mitigate each other so as to reduce cross-talk interference in the sensor. |
