摘要： A glass-film laminate or article having a narrow failure distribution or a Weibull modulus of greater than 10. In embodiments, the glass-film laminate or article includes at least one first film disposed on a strengthened glass substrate. A first film or any additional films can exhibit an average strain-to-failure that is less than the strain-to-failure of the strengthened glass substrate. In embodiments, the first first film is adhered to the glass substrate such that the first film does not exhibit visible delamination from the glass substrate. Methods of forming glass-film laminates or articles with a desired strength level and narrow failure strength distrubution are also disclosed.

In some examples, the article exhibits a color shift of about 2 or less, when viewed at an incident illumination angle in the range from about 0 degrees to about 60 degrees from normal under an illuminant. In one or more embodiments, the articles include a substrate, and an optical film disposed on the substrate. The optical film includes a scratch-resistant layer and an optical interference layer. The optical interference layer may include one or more sub-layers that exhibit different refractive indices. In one example, the optical interference layer includes a first low refractive index sub-layer and a second a second high refractive index sub-layer. In some instances, the optical interference layer may include a third sub-layer.

摘要： One or more aspects of the disclosure pertain to an article including a film disposed on a glass substrate, which may be strengthened, where the interface between the film and the glass substrate is modified, such that the article retains its average flexural strength, and the film retains key functional properties for its application. Some key functional properties of the film include optical, electrical and/or mechanical properties. The bridging of a crack from one of the film or the glass substrate into the other of the film or the glass substrate can be prevented by inserting a crack mitigating layer between the glass substrate and the film.
