Projection-type capacitor touch screen

The utility model provides a projection-type capacitor touch screen including a strengthened glass 10, optical cements (20, 40 and 60) and a three-layer ITO film; the three-layer ITO film comprises an upper-layer ITO film 30, a middle-layer ITO film 50 and a lower-layer ITO film 70; the upper-layer ITO film 30 in the three-layer ITO film serves as an X electrode, the middle-layer ITO film 50 serves as a Y electrode, and the lower-layer ITO film 70 serves as a shielding layer. The optical glass structure utilizing the three-layer ITO film to replace a multi-layer coated, so as to achieve simple processing technique, low probability of breakage, and avoid a difficult problem that bubbles are easily generated when two pieces of glass are pasted together with the optical cement and the paste is difficult. Meanwhile, the thickness of the projection-type capacitor touch screen is greatly reduced; the thickness of the thinnest three-layer ITO film can achieve 0.1 to 0.25mm; and the utility model also has the advantages that the cost of capacitor touch screens is reduced, the rate of good product (up to 80 percent) is improved, and the like.
