A layered structure for an organic light-emitting diode (OLED) device, the layered structure including a light-transmissive substrate and an internal extraction layer formed on one side of the light-transmissive substrate, in which the internal extraction layer includes (1) a scattering area containing scattering elements composed of solid particles and pores, the solid particles having a density that decreases as it goes away from the interface with the light-transmissive substrate, and the pores having a density that increases as it goes away from the interface with the light-transmissive substrate, and (2) a free area where no scattering elements are present, formed from the surface of the internal extraction layer, which is opposite to the interface, to a predetermined depth.

Methods and apparatus are provide for: a substrate having first and second opposing surfaces, and an elastic modulus; and layer(s) having a thickness between first and second opposing surfaces thereof, the first surface of the layer contacting the second surface of the substrate, forming an interface. The layer may exhibit one or more of: a first elastic modulus proximate to the first surface thereof and a second elastic modulus proximate to the second surface thereof, the second elastic modulus being substantially higher than the elastic modulus value, the first elastic modulus being lower than the elastic modulus of the substrate, the second elastic modulus being higher than the elastic modulus of the substrate, and the layer exhibiting an increasing elastic modulus gradient through the thickness thereof from the first elastic modulus to the second elastic modulus.

Certain example embodiments of this invention relate to heatable glass substrates that may be used in connection with lighting applications, and/or methods of making the same. In certain example embodiments, a glass substrate supports an antireflective (AR) coating on a first major surface thereof, and a conductive coating on a second, opposite major surface thereof. Bus bars connect the conductive coating to a power source in certain example embodiments. The substrate may be heat treated (e.g., heat strengthened and/or thermally tempered), with one or both coatings thereon. The heatable glass substrate thus may help provide a chemical and/or environmental barrier for the luminaire or lighting system disposed behind it. In addition, or in the alternative, the heatable glass substrate may help reduce the amount of moisture (e.g., snow, rain, ice, fog, etc.) that otherwise could accumulate on the luminaire or lighting system.

One or more aspects of the disclosure pertain to an article including a film disposed on a glass substrate, which may be strengthened, where the interface between the film and the glass substrate is modified, such that the article has an improved average flexural strength, and the film retains key functional properties for its application. Some key functional properties of the film include optical, electrical and/or mechanical properties. In one or more embodiments, the interface exhibits an effective adhesion energy of about less than about 4 J/m.sup.2. In some embodiments, the interface is modified by the inclusion of a crack mitigating layer containing an inorganic material between the glass substrate and the film.

Embodiments of an article including a substrate and a patterned coating are provided. In one or more embodiments, when a strain is applied to the article, the article exhibits a failure strain of 0.5% or greater. Patterned coating may include a particulate coating or may include a discontinuous coating. The patterned coating of some embodiments may cover about 20% to about 75% of the surface area of the substrate. Methods for forming such articles are also provided.

The invention provides an IG unit comprising two panes and a between-pane space located between the two panes. A desired surface of a selected one of the two panes bears a coating comprising both a transparent conductive oxide film, and an overcoat film located over the transparent conductive oxide film. The IG unit further comprises a bus bar and a transparent conductor bridge each located over the desired surface. The bus bar is spaced apart from the coating and is connected electrically to the transparent conductive oxide film by virtue of the transparent conductor bridge extending from the bus bar to a top surface of the overcoat film. In some embodiments, the IG unit further comprises a frit located over the desired surface and extending around a perimeter thereof. The bus bar is located over the frit. Certain embodiments provide a refrigerator having a door comprising such an IG unit.

A method of forming a coating layer on a glass substrate in a glass manufacturing process includes: providing a first coating precursor material for a selected coating layer composition to at least one multislot coater to form a first coating region of the selected coating layer; and providing a second coating precursor material for the selected coating layer composition to the multislot coater to form a second coating region of the selected coating layer over the first region. The first coating precursor material is different than the second precursor coating material.

A method for preparing a laminate substrate for a light emitting device includes providing a glass substrate having a refraction index, at 550 nm, of between 1.45 and 1.65, coating a glass frit having a refractive index, at 550 nm, of at least 1.7 onto the glass substrate, firing the resulting frit coated glass substrate at a temperature above the Littleton temperature of the glass frit thereby forming a first high index enamel layer, coating a metal oxide layer onto the first high index enamel layer, and firing the resulting coated glass substrate at a temperature above the Littleton temperature of the glass frit, thereby making react the metal oxide with the underlying first high index enamel layer and forming a second high index enamel layer with a plurality of spherical voids embedded in the upper section of the second high index enamel layer near the interface with air.

The invention provides transparent conductive coatings based on indium tin oxide. The coating has an oxide overcoat, such as an alloy oxide overcoat. In some embodiments, the coating further includes one or more overcoat films comprising silicon nitride, silicon oxynitride, silicon dioxide, or titanium dioxide.

A production method for a glass roll includes a start preparation step (S1) of feeding-out a first lead film (LF1) coupled to a starting end portion (GFa) of a first glass film (GF1) from an unwinding device (3) and allowing a winding device (8) to wind the first lead film (LF1 after passing of the first lead film (LF1) through a thermal film-forming device (4),). The start preparation step (S1) includes a temperature increasing step of causing the thermal film-forming device (4) to be increased in temperature to a film-forming temperature. The first glass film (GF1) reaches the thermal film-forming device (4) before the thermal film-forming device (4) is increased in temperature to the film-forming temperature.
