Abstract: A driving and sensing method for a single-layer mutual capacitive multi-touch screen includes inputting a first driving signal to a plurality of touch sensing electrodes along a first direction and receiving a first sensing signal corresponding to the first driving signal along the first direction; and inputting a second driving signal to the plurality of touch sensing electrodes along a second direction and receiving a second sensing signal corresponding to the second driving signal along the second direction; wherein the second direction is substantially perpendicular to the first direction. The plurality of touch sensing electrodes are disposed in the single-layer mutual capacitive multi-touch screen, and each of the plurality of touch sensing electrodes includes at least one driving area and at least one receiving area, wherein all driving areas and receiving areas are located in a same layer of the single-layer mutual capacitive multi-touch screen.
