Abstract
A strengthened film for a substrate such as a glass panel is provided. The strengthened film may be formed by implanting sodium in the film, and then performing an exchange through which the sodium is replaced by potassium. The film may be an anti-reflective coating. Related assemblies and methods are also provided.
Claims20
A method for strengthening, comprising:
- providing a material;
- inserting a first plurality of atoms into the material;
- and
- exchanging a second plurality of atoms respectively defining a relatively greater volume with the first plurality of atoms in the material to strengthen the material.

An electronic device, comprising:
- a display configured to output a graphical image;
- and
- a protective assembly covering the display, the protective assembly comprising:
- a substrate;
- and
- a film coupled to the substrate,
- wherein the protective assembly is strengthened by inserting a first plurality of atoms into at least one of the substrate and the film and exchanging a second plurality of atoms respectively defining a relatively greater volume with the first plurality of atoms.
4 more elements
A computer program product comprising at least one computer-readable storage medium having computer-executable program code portions stored therein, the computer-executable program code portions comprising:
- program code instructions for providing a material;
- program code instructions for inserting a first plurality of atoms into the material;
