Abstract:
Embodiments of the present invention provide a touch screen, an electronic device comprising the same and a method for manufacturing the same. The touch screen comprises driving electrode layers, a transparent organic polymer layer and metal bridges conductively communicated with two adjacent driving electrode layers, and protective layers covering the metal bridges to prevent the oxidation of the metal bridges are disposed between the driving electrode layers and the metal bridges. In the touch screen provided by the embodiment of the present invention, as the metal bridges are respectively covered by the protective layers, the metal bridges will not undergo oxidation reaction due to the contact of transparent organic polymers, and thus the electric conductivity of the metal bridges can be effectively guaranteed; the increase of the impedance of oxide layers can be avoided; and the product yield of the touch screen can be improved.
