Abstract: Setting a slew rate, e.g., a rising time or a falling time, of a scanning signal can be performed with a first operation, and a shunting resistance of the scanning line can be set with a second operation. A scanning system that scans a display screen, a touch screen, etc., can set a desired slew rate during a first period of time and can set a desired shunting resistance during a second period of time. A gate line system can sequentially scan gate lines to display an image during a display phase of a touch screen. The gate line system can, for example, increase the falling times of gate line signals. After the falling gate line signal has stabilized, for example, the gate line system can decrease the shunting resistance of the gate line.
