Title: APPARATUS AND METHOD FOR MASKING THE PERIMETER EDGE OF A GLASS-BASED ARTICLE DURING A COATING PROCESS AND ARTICLES PRODUCED THEREBY
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.
