Abstract
A touch screen, includes a position sensing assembly and a display assembly. The position sensing assembly includes: a substrate, a first polymer layer and a second polymer layer, the first polymer layer is formed on a surface of the substrate, a conductive material is embedded in the first polymer layer to form a first conductive area and a first lead on a surface of the first polymer layer, the second polymer layer is formed on a surface of the first polymer layer; a conductive material is embedded in the second polymer layer to form a second conductive material and a second lead on a surface of the second polymer layer. The touch screen omits a transparent conductive film, and achieves an effect of conducting through embedding a conductive material in the first and second polymer layer, thus material cost is relatively low and the producing process is relatively simple.
