Driving and sensing method for single-layer mutual capacitive multi-touch screen

A driving and sensing method for a single-layer mutual capacitive multi-touch screen wherein a 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 comprises 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, the driving and sensing method comprising:

• inputting a first driving signal to a plurality of driving areas of the plurality of touch sensing electrodes along a first direction, and receiving a first sensing signal corresponding to the first driving signal from a plurality of receiving areas of the plurality of touch sensing electrodes along a second direction, wherein the second direction is substantially perpendicular to the first direction;
• and
• in a specific condition, further inputting a second driving signal to the plurality of driving areas of the plurality of touch sensing electrodes along the first direction and receiving a second sensing signal corresponding to the second driving signal from the plurality of receiving areas of the plurality of touch sensing electrodes along the first direction, and inputting a third driving signal to the plurality of driving areas of the plurality of touch sensing electrodes along the second direction and receiving a third sensing signal corresponding to the third driving signal from the plurality of receiving areas of the plurality of touch sensing electrodes along the second direction.
