SMUDGE, SCRATCH AND WEAR RESISTANT GLASS VIA ION IMPLANTATION

---

Abstract

---

Mechanical properties of a cover glass for a touch screen are improved by ion implanting the front surface. The implant process uses non-mass analyzed ions that physically embed in voids between inter-connected molecules of the glass. The embedded ions create compression stress on the molecular structure, thus enhancing the mechanical properties of the glass to avoid scratches. Also, implanting ions containing fluoride enhances the hydrophobic and oleophobis properties of the glass to prevent finger prints.
