Noise introduced into touch sensor panel measurements, for example, from display data lines of a display device proximate to the touch sensor panel, can be reduced. In some examples, touch sensing operations and display operations can be synchronized. For example, touch sensing scans (or scan steps) can begin with the rising edge of a display line synchronization signal. Additionally, the display noise can be characterized for the system. Display noise characterization and timing synchronization can be used to discard touch sensing samples including display noise injected into the touch sensor panel that may be synchronized to the display data line synchronization signal. In some examples, a window can be generated based on the characterized display noise, and the window can be applied to annihilate display noise. The application of the window can be time-dependent to account for offsets between the occurrence of the display noise and the touch sensing operation.
