A preparation method of capacitive touch screen electro-conductive glass with a shadow eliminating function comprises the following steps: selecting electronic level glass, cutting glass substrates, automatically grinding glass edges, washing, inspecting grinded edges, washing, examining, loading glass sheets on a machine, heating, painting a silicon dioxide baffle membrane, an indium tin oxide membrane, a tantalum pentoxide membrane, and a silicon carbide shadow eliminating membrane on the glass sheets by a magnetron sputtering coating machine, cooling, unloading glass sheets from the machine, and testing the performance of the indium tin oxide membrane. The prepared electro-conductive glass has the advantages of low square resistance, good sheet resistance uniformity, high light transmittance, and short etching time. Two surfaces of the glass are coated, and multiple membranes are continuously plated on the glass. The electro-conducive glass has a shadow eliminating function. The production efficiency is im
