Mutual capacitive touch substrate, display apparatus, touch panel, method of driving mutual capacitive touch substrate, and driver circuit

A method of driving a mutual capacitive touch substrate having a matrix of a plurality of touch electrode blocks along a first direction and a second direction, the plurality of touch electrode blocks grouped into a plurality of touch control repeating units,

• wherein each of the plurality of touch control repeating units comprises a touch sensing electrode, one or more first touch scanning electrodes on a first side of the touch sensing electrode, and one or more second touch scanning electrodes on a second side of the touch sensing electrode, the first side is different from the second side;
• the touch sensing electrode abuts at least a portion of each of the one or more first touch scanning electrodes and at least a portion of each of the one or more second touch scanning electrodes;
• and
• the plurality of touch control repeating units are electrically insulated from each other;
