Abstract
Embodiments of a deadfront article are provided. The deadfront article includes a substrate having a first surface and a second surface. The deadfront article also includes a semi-transparent layer disposed onto the second surface of the substrate. The semi-transparent layer has a region of a solid color or of a design of two or more colors, and the semi-transparent layer has a first optical density. Further, the deadfront article includes a contrast layer disposed onto the region. The contrast layer is configured to enhance visibility of the color(s) of the semi-transparent layer.
Claims20
A deadfront article comprising:
- a substrate comprising:
- a first surface;
- and
- a second surface opposite the first surface;
- a semi-transparent layer disposed on the second surface of the substrate and having an optical density of from 0.1 to 0.5, the semi-transparent layer forming a pattern of two or more colors, wherein the semi-transparent layer is printed onto the second surface of the substrate using a CMYK color model;
- a contrast layer disposed onto at least a portion of the semi-transparent layer, wherein the contrast layer comprises a reflective surface that reflects light in the visible spectrum and renders the pattern visible when the deadfront article is viewed from the first major surface;
- and
- a color layer disposed on the contrast layer, wherein the color layer comprises multiple colors, wherein the semi-transparent layer is printed onto the contrast layer using a CMYK color model.
A display assembly comprising:
- a deadfront article;
- and
- a display, wherein:
- the deadfront article exhibits a pattern of a plurality of colors when not backlit by the display, the pattern being formed by a first ink layer disposed on a surface of a substrate of the deadfront article,
- visibility of the pattern is enhanced by a contrast layer printed on the first ink layer, the contrast layer including a surface that reflects light in the visible spectrum,
- an appearance of the display assembly is determined at least in part by a second ink layer disposed on the contrast layer,
- the second ink layer is printed onto the contrast layer,
- the second ink layer includes multiple colors,
- when the display is off, a border of the display is not visible through the deadfront article, and
- when the display is on, graphics rendered by the display are visible through the deadfront article.
