Patent ID: 8524314

Claim:
A method for manufacturing a touch screen having an inorganic substrate with a bacteria inhibition layer, the method comprising: forming a dispersing solution by uniformly dispersing particles of nano-sized metal material in a solvent, the nano-sized metal material being nano-sized silver (Ag); mixing the dispersing solution with an anti-glare treatment solution which comprises silicate, water, acid and solvent to forum an acid solution so that the acid solution has a concentration of 20 ppm to 500 ppm of nano-sized metal material; evenly coating the acid solution on a surface of the inorganic substrate of the touch screen; and performing a heat treatment to the inorganic substrate at a temperature ranged from 160° C. to 200° C. until the solvent in the acid solution is completely evaporated so that the particles of the nano-sized metal material are densely adhered to the surface of the inorganic substrate of the touch screen to form a bacteria inhibition layer thereon, wherein, the bacteria inhibition layer has a thickness between 50 Å and 5000 Å.
