Methods of manufacturing a layered glass element and various components of a layered class element, such as a pre-form assembly and a woven panel, are disclosed herein. These methods include the step of supplying a woven panel having a plurality of elongated strands woven into an open weave to define a first porous surface opposite of a second porous surface. A layer of interlayer material is applied to the first and second porous surfaces to encapsulate at least a portion of the woven panel within the interlayer material. These elements may be placed between a first and second layer of glass materials. A degree of pressure and heat is then applied for a first period of cure time to bond the interlayer material and the woven panel into either a pre-form assembly or a layered glass element.

Methods for preparing multi-layer optical laminates include placing an optical film that is free form an adhesive layer between first and second glass substrates that are free of an adhesive layer, placing this laminate under vacuum, and then heating the laminate under pressure to a temperature above the softening temperature of the optical film. The glass substrates are free of an adhesive layer but may include a silane surface treatment. The resulting multi-layer laminate is optically clear and does not show scattering of reflected light by the optical film.

A transparent illumination system and related light guide plate is provided. The system is configured to facilitate total internal reflection propagation of light through the light guide plate despite low index of refraction differences between the glass material of the light guide layer and the adjacent layer.

The light guide plate includes internal light extraction features.
