Abstract
A system and method for determining location of a touch event on or in proximity to a touch sensitive device is disclosed. The touch sensitive device includes row conductors and column conductors that each only transmit or receive signals during a given frame. Each of the orthogonal row signals is transmitted on a respective one of at least some of the row conductors. Signals are received on each of the column conductors an amount of each of the row signals present on each of the plurality of column conductors is detected. Orthogonal column signals are transmitted on the column conductors. Signals are received on each of the row conductors and an amount of each of the orthogonal column signals present on each of the row conductors is detected. The detected amount of each of the orthogonal row signals and the detected amount of each of the orthogonal column signals is used to determine a location of a touch event on or in proximity to the touch sensitive device. At least one of the transmitting and receiving steps avoids simultaneously transmitting and receiving on at least one of the row conductors or column conductors.
