Abstract
A system and method for increasing a scanning rate, reducing the effects of noise and reducing power consumption when using a touch sensor having an electrode grid formed by co-planar but orthogonal XY electrodes, wherein the touch sensor may be used to determine the position of an object on a surface of the touch sensor in a single measurement cycle by using a single drive line that defines a touch sensor area and the XY electrodes as sense electrodes of the touch sensor.
