A touch sensing system for avoiding display noises includes a touch display panel, a display driver integrated circuit and a touch control integrated circuit. The display driver integrated circuit is connected to the touch display panel for performing a display operation. The touch control integrated circuit is connected to the touch display panel and the display driver integrated circuit. The touch control integrated circuit performs a touch sensing on the touch display panel in a vertical blanking interval based on a vertical synchronous signal to generate a first set of touch position data, and perform a touch sensing on the touch display panel in a non-vertical blanking interval to generate a second set of touch position data. The touch control integrated circuit updates the second set of touch position data based on the first set of touch position data.
