Abstract
Devices, methods and media relating to a touch sensor and touch-sensor controller. The touch sensor has a plurality of drive lines and sense lines for detecting touch of an object. The touch-sensor controller provides drive signals to particular drive lines within the plurality of drive lines of the touch sensor. In response to a detected touch, the touch-sensor controller sends a first set of drive signals to one or more drive lines within a touch window of the touch sensor and sends a second set of drive signals to one or more drive lines in at least one portion of the touch sensor outside the touch window. The first set of drive signals each have a first number of pulses. The second set of drive signals each have a second number of pulses. The first number of pulses is greater than the second number of pulses.
