Substantially alkali free glasses are disclosed with can be used to produce substrates for flat panel display devices, e.g., active-matrix liquid crystal displays (AMLCDs). The glasses have high annealing temperatures and Young's modulus. Methods for producing substantially alkali free glasses using a downdraw process (e.g., a fusion process) are also disclosed.

High strain point and high young's modulus glasses

A method of forming a glass laminate includes providing a substrate having a core layer and at least one cladding layer; heat treating the substrate at a temperature such that the at least one cladding layer is phase-separated after the heat treating; and etch treating the substrate for at least 10 sec. A phase-separated glass laminate includes a substrate having a core layer and at least one phase-separated cladding layer, such that the glass laminate has a % transmission of at least 96%, and the at least one cladding layer comprises a grain size in a range of 10 nm to 1 μm, or a graded glass index of greater than 5 nm.

Anti-reflection and anti-glare glass laminates

A laminate glass article is provided that includes: a core glass layer comprising a first coefficient of thermal expansion (CTE); and a plurality of clad glass layers, each comprising a first primary surface, a second primary surface in contact with the core glass layer and a second CTE that is lower than the first CTE of the core glass layer. The difference in the first and second CTE is about 10×10/#C to about 70×10/#C. Further, each of the core glass layer and the clad glass layers comprises a viscosity from 10to 10Poise from about 550 #C to about 700 #C.
