Capacitance type touch screen with bi-layer structure

The invention discloses a capacitance type touch screen with a bi-layer structure, which comprises a driving layer and an inductive layer. The driving layer comprises a plurality of mutually-parallel driving lines, the inductive layer comprises a plurality of mutually-parallel ITO (Indium Tin Oxide) inductive lines, and the driving lines are mutually vertical to the ITO inductive lines. The driving lines have the constant widths, the ITO inductive lines are of a string of bead shape and are formed by connecting a plurality of same inductive units in series, and each inducting unit is of a sandglass or olive shape. Compared with traditional screen body structures of rhombic driving lines and rhombic inductive lines, the capacitance type touch screen with the bi-layer structure disclosed by the invention has the advantages of reducing the resistances of the inductive lines, increasing the effective capacitance and improving the space uniformity of the touch by changing the shapes of the upper layer inductive lines on the premise of not losing a capacitance touch property.
