The two sets of wires in the X direction and the Y direction are spatially intersected, and the process is to sequentially deposit the underlying conductive layer, the insulating layer and the upper conductive layer. Since the transparent conductive layers of the two sets of wires must be separately fabricated, the color difference between the two conductive layers is caused, and the quality of the touch screen is lowered. [0006] 4. Since the touch screen lacks a shielding structure, the touch screen cannot shield the display from the display. The electromagnetic interference caused the performance of the touch screen to be affected.
