Claim:
1. A processing system configured for simultaneously updating a display and performing capacitive sensing, the processing system comprising: a source driver configured to drive a source line with a first source driver voltage during a first time period and to receive resulting signals on a routing trace coupled to a sensor electrode during a second time period that at least partially overlaps with the first time period, the routing trace and the source line being routed proximate each other; and an interference remover configured to acquire first resulting signals during a first display update period and second resulting signals during a second display update period, and to remove display interference from the second resulting signals by combining the first resulting signals and the second resulting signals, wherein first display signals provided for display updates during the first display update period are frame-inverted with respect to second display signals provided for display updates during the second display update period.
