1. A detection method for a capacitive touch screen, comprising:

  • providing a capacitive touch screen, including;

    a conductive strip pattern having a plurality of conductive strips exposed from each other, the conductive strip pattern including;

    a plurality of first conductive strips operatively provided with a driving signal during mutual capacitive detection, wherein each first conductive strip includes a plurality of first connecting lines aligned in a first direction and a plurality of first conductive pads aligned in a second direction, and the first connecting lines are connected with the first conductive pads; and

    a plurality of second conductive strips providing mutual capacitive coupling signals, the first conductive strips and the second conductive strips being exposed and separated from each other, wherein each second conductive strip includes a plurality of second connecting lines aligned in the second direction and a plurality of second conductive pads aligned in the first direction, and the second connecting lines are connected with the second conductive pads; and

    simultaneously and continuously providing the driving signal to at least one first conductive strip, and providing a direct current (DC) signal to first conductive strips not driven by the driving signal; and

    generating sensing information based on the mutual capacitive coupling signals provided by the second conductive strips each time the driving signal being provided.
