Please refer to FIG. 1, which is a schematic diagram of a prior art touch screen display device. The touch screen display device i includes a liquid crystal panel 16 and a: a touch screen 10 disposed on the liquid crystal panel 16, the liquid crystal panel 16 includes a main circuit board 19, and the touch screen 1 is coupled to the main body by a flexible circuit board 18. The circuit board 19 is connected. The touch screen 10 includes a transparent conductive substrate u, a transparent conductive film 12, a protective layer 13, an adhesive layer 17, and a plurality of dot spacers 14, and the transparent conductive film; [2] The plurality of dots 14 are evenly spread between the transparent conductive substrate u and the transparent conductive film 12, by the dead layer being together. The protective layer 13 is disposed outside the transparent conductive film 12. The circuit structure of the touch screen 10 is as shown in FIG. 2. The edge of the transparent conductive substrate 11 is provided with two parallel electrodes 15A. The edge of the transparent conductive film 12 is also provided with two parallel electrodes 150, and the two parallel electrodes 150 of the transparent conductive film 12 are parallel to the two of the transparent conductive substrate n. The electrode 15 is perpendicular. Two transparent pads 152 are disposed at one corner of the transparent conductive substrate 11, and the corresponding positions of the transparent film 200842683 are also provided with two solder joints 152, which are separated from each other. The four electrodes 150 are connected to the four pads 152 by wires 153, respectively. The four pads 152 are respectively connected to the four pads 151 on the flexible circuit board 18.
