Method for controlling touch panel

A method for controlling a touch panel comprising:

• providing the touch panel comprising a driving layer and a sensing layer opposite to the driving layer;
• the driving layer comprising a first conductive layer and a plurality of driving electrodes located on a side of the first conductive layer along a first direction;
• the sensing layer comprising a second conductive layer and a plurality of sensing electrodes located on a side of the second conductive layer along a second direction cross with the first direction;
• wherein the sensing layer is divided into a first area and a second area along a boundary parallel to the first direction, the plurality of sensing electrodes located on the first area are defined as first sensing electrodes, the plurality of sensing electrodes located on the second area are defined as second sensing electrodes;
• applying a first driving signal V1 to the plurality of driving electrodes one by one, obtaining a plurality of first electrical signals by scanning the first sensing electrodes one by one, and converting the plurality of first electrical signals into a plurality of first digital signals by digital analog conversion with a first amplified factor κ;
• and
• applying a second driving signal V2 to the plurality of driving electrodes one by one, obtaining a plurality of second electrical signals by scanning the second sensing electrodes one by one, and converting the plurality of second electrical signals into a plurality of second digital signals by digital analog conversion with a second amplified factor κ′;
• wherein the second driving signal V2 is greater than the first driving signal V1.
