Abstract: Methods for coating a glass-based article, for example a cover glass, with a coating layer that is not deposited on the perimeter edge of the glass-based article. The methods may include disposing a mask having an eave over a glass-based article to protect perimeter portions of the glass-based article from coating of the coating layer during a deposition process. The eave may be dimensioned to form a coating layer having non-uniform coating thickness region around the edge of the coating layer that is not visible to the naked eye on the surface of a glass-based article. The methods may be used to make a glass-based article with non-edge-to-edge coating layers.

Abstract: Methods for coating a glass-based article, for example a cover glass, with a coating layer that is not deposited on the perimeter edge of the glass-based article. The methods may include direct patterning of a sacrificial material over a first region on a top surface the glass-based article but not a second region on the top surface of the glass-based article. The first region includes at least a portion of a perimeter edge of the glass-based article that is to be protected from deposition of the coating layer. After direct patterning of a sacrificial material and deposition of a coating layer, the sacrificial material may be removed such that the coating layer is disposed on the second region on the top surface of the glass-based article and not the first region. These methods may be used to make a glass-based article with non-edge-to-edge coating layers.
