Abstract
A touch sensitive system includes a touch surface, a display, and a latency control system. The latency control system reduces the latency between a touch event occurring on the touch surface and a graphical response displayed by the display. Specifically, the latency control system is a feedback system that synchronizes touch scan and display operations. The touch scan and display operations are synchronized by adjusting timing parameters, such as the start times and frequencies of the scan and display operations. Thus, the latency control system is an adaptable system that may reduce latency even when the processing times of various operations vary over time.
