1. the method for making of a touch circuit two-sided graph structure is characterized in that, comprises following steps:

  • Provide a substrate, two-sided one first conductive base layer and the one second conductive base layer laid respectively of this substrate;

    At this first conductive base layer end face contact, one isolated ultraviolet barrier bed;

    Contact one first photoresist layer in this barrier bed end face, and contact one second photoresist layer in this second conductive base layer bottom surface;

    This first photoresist layer is exposed, and this second photoresist layer is exposed, during by the isolated two-sided ultraviolet ray of this substrate of this barrier bed;

    Develop simultaneously to this substrate is two-sided, impel this first conductive base layer and this second conductive base layer to expose one separately and wait to accept etched zone;

    AndThis first conductive base layer and this second conductive base layer exposed regions are carried out etching simultaneously, impel this first conductive base layer to form one first conducting film of this touch-control circuit, and this second conductive base layer forms one second conducting film of this touch-control circuit.
