Abstract
A substrate () comprising a sheet of either a glass, a glass ceramic, or a ceramic and having increased edge strength. A polymeric edge coating () prevents creation of strength limiting defects along the edges of the substrate and protects the bend strength of the edges. The substrate may also have at least two parallel high strength edges () and an edge coating () of a polymeric material covering at least a portion of each of the high strength edges to preserve the high strength edges from the introduction of defects and damage to the edges. Each of the two parallel high strength edges has a bend strength that is capable of less than about 2% failure probability at a stress level of 200 MPa over a test length of 50 mm. A method of making the substrate is also provided.
