A device for displaying images having variable colors comprises a substrate; a light-transmissive coloring layer painted or laminated on the substrate, the coloring layer comprising colorants of different colors and having a rear side in contact with the substrate and a varnished front side; a display layer comprising a silvering material directly plated on the varnished front side of the coloring layer, the display layer comprising a display pattern forming a visible displayed image, the silvering material comprising a metal, a metalloid, or an oxide thereof to form a one-way-mirror; an illuminator configured and positioned to illuminate the coloring layer from the rear side of the coloring layer. When the coloring layer is unilluminated by the illuminator, the unilluminated coloring layer is hidden behind the one-way-mirror. When the coloring layer is illuminated by the illuminator, the illuminated coloring layer visibly colorizes the displayed image through the one-way-mirror.

A metallized plastic component includes a base body of at least one light-permeable plastic to which a metal layer is applied into which at least one illuminatable structure is introduced. The at least one illuminatable structure is formed by an area in the metal layer in which a plurality of light-permeable openings is arranged in a dot matrix.

A decorative sheet includes a decorative layer. Holes arranged in a plurality of directions are provided in the decorative layer. An average of values of an array pitch of holes arranged in a first array direction, in which the array pitch has a least value among the plurality of directions, and a standard deviation thereof, and an average of values of an array pitch of holes arranged in a second array direction, in which the array pitch has a second least value among the plurality of directions, and a standard deviation thereof, meet particular conditions.

A method for producing a plastic article including a) providing at least one film 10 having a carrier film and at least one decorative layer, b) forming, by means of lasers, at least one first area 21 and at least one second area 22 in the plane formed by the at least one film 10, wherein the at least one second area 22 has a higher transmittance than the at least first area 21, c) arranging at least one varnish layer 12 in the at least one second area 22 by means of digital printing, d) curing, the at least one film 10, and/or the at least one varnish layer 12, e) arranging the at least one film 10, on a substrate 11, f) obtaining a plastic article 1 comprising the at least one first area 21 and the at least one second area 22.

A display device includes a window panel over a display panel. The window panel includes a display area to transmit an image generated by the display panel and a non-display area adjacent the display area. The window panel includes a first light-shielding printed layer and first to third decor printed layers. The first light-shielding printed layer is in the non-display area. The first decor printed layer is in the non-display area and covers a side surface of the first light-shielding printed layer and at least a portion of an upper surface of the first light-shielding printed layer. The second decor printed layer is on the first light-shielding printed layer and the first decor printed layer. The second light-shielding printed layer is on the first light-shielding printed layer and the second decor printed layer.

An intelligent container is provided. The container includes a body; and a light-emitting device disposed on the body. The light-emitting device includes at least one light-emitting unit, the light-emitting unit being configured to emit light towards the inside of the body and the outside of the body. The light-emitting unit of the intelligent container can emit light bidirectionally to provide a light source for a plant therein in the growth process of the plant, and simultaneously provide an illumination to the outside.

A method of making a multi-layered film includes depositing thin film layers onto a first side of a double-sided transparent substrate. The thin film layers are transparent, and two adjacent layers of said plurality of thin film layers have different refractive indices. One or more absorbers are deposited at an interface formed between two of the thin film layers that are adjacent to one another, or formed by the first side of the substrate and one of the thin film layers. The absorbers absorb selected wavelengths of incident light and reflect part of the incident light after inducing a phase shift. The location of the interface is selected to provide desired wavelengths of absorbed and reflected light. The multi-layered film has a first appearance when viewed from the first side of the substrate and a second appearance when viewed from the second side of the substrate.
