PROBLEM TO BE SOLVED: To provide a low-load driving method, driver integrated circuit employing the same, and touch display system.SOLUTION: A driver integrated circuit (IC) is arranged to selectively operate in a display mode and touch-sensing mode when the driver IC is coupled to a touch display panel. When the driver IC operates in the display mode, the driver IC controls a plurality of common voltage lines of the touch display panel to have a common voltage. When the driver IC operates in the touch-sensing mode and provided that a specific common voltage line is arranged to detect a current touch, the driver IC controls a first source line of the touch display panel which corresponds to the specific common voltage line, or controls a neighboring common voltage line of the specific common voltage line, to have a first signal pattern the same as the first signal pattern on the specific voltage line or to be floating.SELECTED DRAWING: Figure 5 |
