An insulated glass unit is described and includes at least a first glass layer, a second glass layer and a third glass layer disposed therebetween. The third glass layer is separated from the first glass layer and the second glass layer by first and second sealed gap spaces. The third glass layer has a low CTE as compared to the CTE of the first and/or second glass layers. In some instances, the third glass layer has a CTE of less than 70×10.sup.−7/° C. over a temperature range of 0-300° C.

In some embodiments, a process comprises fixing a first portion of a flexible glass substrate into a first fixed shape with a first rigid support structure and attaching a first display to the first portion of the flexible glass substrate or to the first rigid support structure. After fixing the first portion and attaching the first display, and while maintaining the first fixed shape of the first portion of the flexible glass substrate and the attached first display, cold-forming a second portion of the flexible glass substrate to a second fixed shape and fixing the second portion of the flexible glass substrate into the second fixed shape with a second rigid support structure.

The method for manufacturing the gas adsorption unit includes a preparation step, an activation step, and a sealing step. The preparation step is a step of wrapping a getter with a package material. The activation step is a step of heating the getter wrapped with the package material to activate the getter. The sealing step is a step of melting the package material by heating the package material so as to seal, with the package material, the getter activated in the activation step.

A pre-fractured glass laminate that includes: a glass substrate comprising a thickness, a pair of opposed primary surfaces, a compressive stress region, a central tension (CT) region and a plurality of cracks; a second phase comprising a polymer or a cured resin within the plurality of cracks; a backing layer; and an interlayer disposed between one of the primary surfaces of the substrate and the backing layer. The compressive stress region extends from each of the primary surfaces to a first selected depth in the substrate. Further, the plurality of cracks is located in the CT region.
