Abstract
In certain embodiments, a touch sensor controller estimates an area of a display screen that a display controller will update at a first time and estimates an area of a touch sensor that the touch sensor controller is expected to scan at the first time. The touch sensor controller further identifies an expected interference based on a comparison between the update of the estimated area of the display screen by the display controller at the first time and the scan of the estimated area of the touch sensor by the touch sensor controller at the first time. Based on the expected interference, the touch sensor controller suspends, for a first time period, the scan of the estimated area of the touch sensor for touch events based on the expected interference. The touch sensor controller resumes the scan after the first time period.
