An organic light emitting diode includes a substrate having a surface modification layer. The surface modification layer includes a first film and a second film. The first film has a coefficient of expansion that is greater than the coefficient of expansion for the second film. The second film has ridges and troughs. A method of making a surface modification layer. A first film is formed over a substrate. The coated substrate is heated to expand the first film to a second surface area. A second film is formed over the expanded first film. The substrate coated with the first and second films is cooled to form ridges and troughs in the second film.

An organic light emitting diode () includes a substrate () having a first surface () and a second surface (), a first electrode (), and a second electrode (). An emissive layer () is located between the first electrode () and the second electrode (). The organic light emitting diode () further includes a surface modification layer (). The surface modification layer () includes a non-planar surface ().

A coated article includes a non-conductive substrate, such as glass. At least one conductive coating is formed over at least a portion of the substrate, such as by chemical vapor deposition or physical vapor deposition. The conductive coating can be a functional coating and can have a thickness in the range of greater than 0 &#x212b; to less than 25,000 &#x212b;, such as less than 10,000 &#x212b;. At least one polymeric coating is electrodeposited over at least a portion of the conductive coating.

A reflective article, such as a solar mirror, includes a highly transparent substrate having a first major surface and a second major surface. At least one reflective coating is formed over at least a portion of one of the surfaces, e.g., the second major surface (or, alternatively, the first major surface). The reflective coating includes at least one metallic layer. An encapsulation structure can be formed over at least a portion of the second reflective coating.

Reflective article and method of making a reflective article

Reflective article

An article includes a substrate, e.g. a glass sheet having a first major surface and an opposite second major surface having a textured surface to provide a predetermined pattern on the second surface of the substrate, and an overlay, e.g. a coating over the pattern. The percent of visible light transmittance, and percent visible light reflectance, of the substrate and the overlay is selected such that the pattern is visible when the article is viewed through one of the surfaces of the substrate or overlay. In one non-limiting embodiment, the substrate is glass and the article has a metallic appearance. In another non-limiting embodiment, the overlay is a transparent coating deposited on the second surface of the glass sheet into grooves of the pattern. Other non-limiting embodiments include the substrate having a Delta % haze of greater than 15%, and a protective overcoat over the coating.

A method and coating are provided for temporarily protecting a substrate or article during shipping, handling or storage by applying a removable protective coating over at least a portion of the substrate. The substrate may be flat or curved and may have zero, one or more functional coatings. A plurality of substrates with the protective coating of the invention may be arranged in a shipping container so that the protective coating reduces the possibility of damage to the substrate or optional functional coating. In one embodiment, the protective coating is the evaporation or reaction product of an aqueous coating composition containing a polyvinyl alcohol polymer which may be subsequently removed by aqueous washing, thermal decomposition or combustion. In another embodiment, the protective coating is formed by sputtering a substantially carbon coating onto the substrate. The carbon coating is subsequently removed by combustion. The protective coating may have identification materials, such as colorants or fragrance materials, such that different types of substrates and/or functional coatings can be distinguished from each other. Additionally, the temporary protective coating can improve the heating of a functionally coated glass substrate.

The present invention is directed to an article with a patterned appearance provided by a visually observable contrast between one or more genereally transparent thin film coatings deposited over a substrate. At least one of the deposited coatings exhibits a reflected color and/or contrast and visible differing transmitted color and/or contrast or a plurality of coatings together exhibit different reflected colors and/or contrasts. The coatings are selected from the group of: metals depositable by magnetron sputtering vacuum deposition, chemical vapor deposition, pyrolytic coating, or sol-gel techniques, metal oxide coatings, metal nitride coatings, semi-conductor containing coatings, metal oxynitrides and mixtures thereof. The present invention is also directed to a method of making the articles having a visually observable patterned appearance involving masking and applying the coating or applying the coating and removing a portion of the coating to form the pattern.

The present invention is directed to an article with a patterned appearance provided by a visually observable contrast between one or more generally transparent thin film coatings deposited over a substrate. At least one of the deposited coatings exhibits a reflected color and/or contrast and visible differing transmitted color and/or contrast or a plurality of coatings together exhibit different reflected colors and/or contrasts. The coatings are selected from the group of: metals depositable by magnetron sputtering vacuum deposition, chemical vapor deposition, pyrolytic coating, or sol-gel techniques, metal oxide coatings, metal nitride coatings, semi-conductor containing coatings, metal oxynitrides and mixtures thereof. The present invention is also directed to a method of making the articles having a visually observable patterned appearance involving masking and applying the coating or applying the coating and removing a portion of the coating to form the pattern.

A layer for protecting an underlying functional coating stack for example a single silver layer or double silver layer Low-E coating stack includes silicon oxynitride or silicon aluminum oxynitride layer. The protective film may have a uniform composition throughout its thickness i.e. homogeneous protective layer, a constantly increasing or decreasing index of infraction throughout its thickness i.e. a graded protective layer, or a combination of all or some of the foregoing i.e. a non-homogeneous protective layer. The graded and non-homogeneous layers may have an outer surface of silicon nitride, silicon aluminum nitride, silicon dioxide, silicon oxynitride or silicon aluminum oxynitride. The protective layer of the invention may be the last layer deposited on the functional coating stack or may have a film deposited thereon.

Multilayer high transmittance, low emissivity coatings deposited over transparent substrates have improved mechanical durability, e.g. scratch resistance by the inclusion of at least one mechanical durability enhancing layer (hereinafter 'MDE layer'). The MDE layer includes one or more pairs of a zinc oxide sublayer having deposited thereover a sublayer of an oxide of zinc and tin. In one embodiment of the present invention, the MDE layer is composed of two sublayers which includes a first sublayer of an oxide of zinc having deposited thereover a second sublayer of an oxide of zinc and tin. In another embodiment of the invention, the MDE layer is composed of four sublayers which includes a first sublayer of an oxide of zinc, having deposited thereover a second sublayer of an oxide of zinc and tin, having deposited thereover a third sublayer of an oxide of zinc, having deposited thereover a fourth sublayer of an oxide of zinc and tin. Coated articles having the MDE layer of the invention can be thermally processed for tempering, heat strengthening, annealing or bending without haze formation and can be manipulated prior to such thermal processing with little or no surface scratching appearing after such thermal processing.
