In certain embodiments, a system includes first and second resistive components and a touch sensor controller. The first component is positioned on a first sense line connected to an in-cell touch sensor. The first resistive component is set to a value modifying an RC time constant of a first electrode of the touch sensor. The second resistive component is positioned on a second sense line connected to the in-cell touch sensor. The second component is set to a value modifying an RC time constant of a second electrode of the touch sensor. The value of the modified RC time constant of the first electrode is within 100% of the value of the modified RC time constant of the second electrode. The controller receives signals from the first and second sense lines, such that the first and second resistive components are between the controller and the first and second electrodes, respectively.
