Provided are multi-component films useful as optical display filters. The optical display filters include a multi-layer stack that contains at least one organic layer. The filters have high visible light transmittance, low visible light reflection, and provide electromagnetic interference shielding.

Multi-component films for optical display filters

Provided are multi-component films useful as optical display filters. The films include a transparent substrate, a nucleation layer, an electrically-conductive layer, a barrier layer, and a dielectric layer. The films can provide high visible transmission, are corrosion-resistant, and can provide shielding from electromagnetic interference (EMI shielding). The optical display filters are useful as components of active optical devices such as display panels including liquid crystal display panels such as those used on mobile hand-held phones.

Patterning an organic light emitting diode (OLED) after it has been encapsulated by permanently changing the light emissivity of the diodes. The OLED includes an intervening layer between a source of laser treatment and a light emitting layer. Depending on the composition of the light emitting layer, the laser treatment will enhance or diminish brightness.

Internally replenished gas-containing enclosures are described. Such enclosures include a replenishing gas source internal to the enclosure, wherein the gas source comprises a gas contained within a permeable membrane. Exemplary gas sources include a plurality of bubbles and pouches. Materials useful for the permeable membrane include glass, glass ceramics, metals, metal oxides, polymeric films, as well as combinations of such materials. The gas source may be located within the enclosure or it may be incorporated into a resin (e.g., an adhesive or a gasket) positioned between sections of an enclosure. Methods of internally replenishing an enclosure are also described.

Patterning an organic light emitting diode (OLED) after it has been encapsulated by permanently changing the light emissivity of the diodes. The OLED includes an intervening layer providing a pressure sensitive touch panel or touch screen panel. Depending on the composition of the light emitting layer, the laser treatment will enhance or diminish brightness.

A shock indicator is described comprising (A) a base having a first side and a second side; (B) an indicator associated with the first side of the base, the indicator comprising a plurality of indicator subparts, the subparts comprising solid material arranged (i) in a first configuration when the shock indicator is in a first state prior to a shock event, and (ii) in a second configuration when the shock indicator is in a second state following a shock event; and (C) means associated with the second side of the base for attachment of the shock indicator to a surface. A method of manufacture is also provided.

A laser imaging system for direct imaging with high optical power density a series of pixels forming an image on a media surface, The laser imaging system includes a laser light source, wherein the laser light source emits a laser beam representative of the image on the media surface. An optical path is defined between the laser light source and the media surface. A scanner is provided having a mirrored surface positioned along the optical path. An optical assembly is positioned along the optical path for shaping and focusing the laser beam at the media surface, including an F-Theta lens assembly positioned along the optical path between the scanner and the media surface. The F-Theta lens assembly includes a spheric lens, an aspheric lens and a toric lens, providing an increase in optical power density at the media surface.

Direct laser imaging system

A method of imaging an article comprising a metal/metal oxide imageable layer with a laser beam. In particular, the present invention relates to a method for imparting a color image on the article. The method includes: a) providing an article including a substrate and an imageable layer, the imageable layer comprising a metal/metal oxide layer; b) imagewise applying a laser beam to the article; and c) in the portion of the article having the laser applied thereto, imparting a color to the metal/metal oxide layer different from the color in the non-imaged portion. Preferably, the imageable layer comprises aluminum/aluminum oxide. Also presented are imageable articles, and the resulting imaged articles.

Flexible optically uniform sign face substrate comprising at least one layer of durable thermoplastic sheeting and an optically uniform dimensionally stable scrim film, and more particularly a sign face substrate comprising at least one layer of optically uniform dimensionally stable multilayer scrim film laminated between at least two layers of durable thermoplastic sheeting for use in areas such as awning, canopy, fascia or sign material construction.

Flexible optically uniform sign face substrate

A process and composition are provided that provide for thermal transfer of ink compositions and eliminate the need to prepare articles such as sign faces, particularly flexible sign faces, by painting with ink compositions that contain solvents. The present process and composition permit thermal transfer from a carrier to a receptor at low temperatures with the use of vacuum pressure. The transferred ink adheres tenaciously to the receptor and is flexible.
