1. a kind of touch screen characterized by comprisingMultiple same layers are arranged and mutually independent self-capacitance electrode, multiple self-capacitance electrodes are arranged in array;

  • The a plurality of conducting wire self-capacitance electrode being connected at the frame of the touch screen;

    Wherein, conducting wire and phase described in each itemMutual spaced two self-capacitance electrodes are electrical connected, non-cross between conducting wire described in each item, and with each conducting wire electrical propertyIt is not overlapped mutually between connected each self-capacitance electrode;

    At least in the intermediate region of the touch screen, two are spaced between two self-capacitance electrodes of the connection of conducting wire described in sameSelf-capacitance electrode;

    The periphery cabling to connect one to one at the frame of the touch screen and with conducting wire described in each item;

    It is electrically connected by connecting terminal and the periphery cabling and for passing through each self-capacitance of detection in the touch-control periodThe capacitance variation of electrode is to judge the touch detection chip of position of touch.
