Abstract: Articles including a substrate, a cover glass layer disposed over a top surface of the substrate, and an adhesive layer having a dynamic elastic modulus disposed between a bottom surface of the cover glass layer and the top surface of the substrate. The cover glass layer may have a thickness in the range of 1 micron to 200 microns. The dynamic elastic modulus of the adhesive layer may include a first elastic modulus in the range of 10 kPa to 1000 kPa measured at a stress frequency in the range of 0 Hertz to 5 Hertz and a temperature of 23 degrees C., and a second elastic modulus of 500 MPa or more measured at a stress frequency in the range of 10 Hertz to 1000 Hertz and a temperature of 23 degrees C. The adhesive layer may be optically transparent. The articles may be bendable electronic display devices or bendable electronic display device modules.

Abstract: A substrate including a via with a beveled overburden is disclosed. The substrate can include a substrate having a first surface, a second surface opposite the first surface, and a via passing from the first surface to the second surface. The via can be coated with a metallic layer that includes a first beveled overburden on the first surface, and the first beveled overburden can include a first outer edge that forms a first bevel angle greater than 95° with the first surface. The substrate can include a second beveled overburden that includes a second outer edge that forms a second bevel angle greater than 95° with the second surface. Methods of making the beveled overburdens are also disclosed.

Abstract: A via includes a substrate and a porous electrically conductive material. The substrate includes a first surface and a second surface opposite to the first surface. The substrate includes a through-hole extending from the first surface to the second surface. The porous electrically conductive material extends through the through-hole. The porous electrically conductive material includes a first porosity in a central region of the through-hole and a second porosity less than the first porosity proximate the first surface and the second surface of the substrate.

Abstract: A foldable electronic device module includes a glass cover element having a thickness from about 25 μm to about 200 μm, an elastic modulus from about 20 GPa to about 140 GPa and a puncture resistance of at least 1.5 kgf. The module further includes a stack with a thickness between about 100 μm and about 600 μm; and a first adhesive joining the stack to the cover element with a shear modulus between about 1 MPa and about 1 GPa. The stack further includes a panel, an electronic device, and a stack element affixed to the panel with a stack adhesive. Further, the device module is characterized by a tangential stress at a primary surface of the cover element of no greater than about 1000 MPa in tension upon bending the module to a radius from about 20 mm to about 2 mm.
