Abstract: Compounds, compositions, articles, devices, and methods for the manufacture of light guide plates and back light units including such light guide plates made from glass. In some embodiments, light guide plates (LGPs) are provided that have similar or superior optical properties to light guide plates made from PMMA and that have exceptional mechanical properties such as rigidity, CTE and dimensional stability in high moisture conditions as compared to PMMA light guide plates.

Abstract: A method includes heating a glass preform having a plurality of glass layers and drawing the glass preform in a distal direction to form a drawn glass sheet extending distally from the glass preform and having the plurality of glass layers. The drawn glass sheet is thinner than the glass preform. The drawn glass sheet can be rolled onto a collection spool. At least a portion of a glass layer can be removed from the drawn glass sheet. An exemplary glass sheet includes a first glass layer, a second glass layer adjacent to the first glass layer, and a thickness of at most about 0.1 mm. An exemplary ion exchanged glass sheet includes a thickness of at most about 0.1 mm and a surface layer that is under a compressive stress and extends into an interior of the glass sheet to a depth of layer.

Abstract: Computer-implemented methods and apparatus are provided for predicting/estimating (i) a non-equilibrium viscosity for at least one given time point in a given temperature profile for a given glass composition, (ii) at least one temperature profile that will provide a given non-equilibrium viscosity for a given glass composition, or (iii) at least one glass composition that will provide a given non-equilibrium viscosity for a given time point in a given temperature profile. The methods and apparatus can be used to predict/estimate stress relaxation in a glass article during forming as well as compaction, stress relaxation, and/or thermal sag or thermal creep of a glass article when the article is subjected to one or more post-forming thermal treatments.

Abstract: A silicate glass that is tough and scratch resistant. The toughness is increased by minimizing the number of non-bridging oxygen atoms in the glass. In one embodiment, the silicate glass is an aluminoborosilicate glass in which −15 mol %≤(R2O+R′O−Al2O3−ZrO2)−B2O3≤4 mol %, where R is one of Li, Na, K, Rb, and Cs, and R′ is one of Mg, Ca, Sr, and Ba.
