Abstract
A processing system configured to receive a first display control signal corresponding to a non-display update period of a display frame and a second display control signal corresponding to a display update period of the display frame. The processing system is further configured to acquire, based on receipt of the first display control signal, first resulting signals from sensor electrodes electrically connected to the sensor driver by operating the sensor electrodes for a first type of input sensing during a first period overlapping with at least a portion of the non-display update period. Further, the processing system is configured to acquire, based on receipt of the second display control signal, second resulting signals with the sensor electrodes by operating the sensor electrodes for a second type of input sensing during a second period overlapping with at least a portion of the display update period.
