A touch screen is disclosed. In some examples, the touch screen comprises a touch sensor panel including a plurality of touch pixels that include a first and a second touch pixel, a first sense connection coupled to the first touch pixel, and a second sense connection coupled to the second touch pixel. In some examples, a touch controller is configured to detect an object coupled to the first touch pixel and the second sense connection, and in response to detecting the object, output substantially no touch signal associated with the second touch pixel. In some examples, the touch controller is further configured to scale a first touch signal associated with the first touch pixel by a first correction coefficient corresponding to the first touch pixel and the second touch pixel, and subtract the scaled first touch signal from a second touch signal associated with the second touch pixel.
