Title: MASKING AND FIXTURING 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 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.
