Preferably, the described line of induction and described drive wire are two.Therefore, the touch accuracy of button 2 can be improved, but also be that button is easy to make.
As shown in Figure 1 to Figure 3, in embodiments more of the present utility model, drive singal cabling circuit 232 is many, and many drive singal cabling circuits 232 are all from the same side of the second patterned layer 231 along drawing.Therefore, the many drive singal cabling circuits 232 of drawing from homonymy so that the wiring of touch-screen module 100, but also can improve the stability of touch-screen module 100 further.
Further, the surface of at least one in induced signal cabling circuit 222 and drive singal cabling circuit 232 is provided with insulating protective layer 26.Therefore, the stability of induced signal cabling circuit 222 and drive singal cabling circuit 232 can be improved, avoid the situation that circuit corrosion or short circuit occur.
Preferably, insulating protective layer 26 is ink, and the thickness of ink is less than 2 microns.Therefore, not only effectively can improve the stability of circuit, but also the thickness of touch-screen module 100 can be reduced.
Further, transparent conductive film (i.e. ITO) is in the first patterned layer 221 and the second patterned layer 231.
As shown in Figure 3, in embodiments more of the present utility model, the first transparency conducting layer 22 bonds on cover plate 21 by the first adhesive linkage 24, and the second transparency conducting layer 23 is bonded on the first transparency conducting layer 22 by the second adhesive linkage 25.Thus improve the stability of button 2.
Preferably, at least one in the first adhesive linkage 24 and the second adhesive linkage 25 is double sided optical glue, and the thickness of at least one in the first adhesive linkage 24 and the second adhesive linkage 25 is in the scope of 0.05 millimeter to 0.125 millimeter.Not only can improve the stability of button 2 structure, but also the thickness of button 2 can be reduced.
Advantageously, cover plate 21 is glass cover-plate, and the thickness of glass cover-plate is in the scope of 0.4 millimeter to 1.0 millimeters.Reduce the thickness of button 2 further.
The touch-screen module 100 of the utility model specific embodiment is simply described with reference to the accompanying drawings.
As shown in Figure 1 to Figure 3; touch-screen module 100 of the present utility model comprises: cover sheet, button 2 (or thin film sensor, Film Sensor), flexible print circuit board (Flexible Printed Circuit; i.e. FPC) and combination drive part, this touch-screen module can be capacitance touch screen module or electric resistance touch screen module etc.
