A decoration member including: a color developing layer including a light reflective layer and a light absorbing layer provided on the light reflective layer; and a substrate provided on one surface of the color developing layer. The substrate includes a pattern layer, and the light absorbing layer includes silicon (Si).

An embossed sheet configuring a decorative sheet includes a sheet-shaped base that has translucency, and a plurality of reflective portions provided on one surface of the base. Each of the plurality of reflective portions has a reflective main surface that reflects incident light, and connecting surfaces that are provided between the reflective main surface and the base. Each reflective main surface is rectilinear on a first cross-section and curvilinear on a second cross-section. A gradient of a straight line at a center position of the reflective main surface that is rectilinear on the first cross-section, in relation to the one surface of the base, varies within a range of ±40 degrees in each of the plurality of reflective portions. As a result, the reflective portion can reflect incident light at regular and non-regular angles.

A decoration method of a printed matter includes: forming a printed layer on a surface of a sheet or of a mounting paper with a transparent varnish, printing a predetermined pattern on the surface of the printed layer by an ink or by a resin which are capable of being adhered to the printed layer; and pressing a metal foil onto the pattern printed by the ink or the resin with an adhesive agent. The adhesive agent does not adhere to the printed layer but adheres to the pattern. As a result, the metal foil 6 is printed only to the pattern.

Provided are an electronic device housing, a preparation method therefor and an electronic device therewith. The electronic device housing comprises a housing body and a logo layer, wherein the housing body is provided with a first surface and a second surface which are opposite each other, the first surface is provided with a first area and a second area which are adjacent to each other, the second area is located on the periphery of the first area, and the surface roughness of the second area is greater than that of the first area; and the logo layer is arranged on the first surface, and an orthographic projection of the logo layer on the first surface coincides with the first area.

The present disclosure discloses an emblem structure in which an emblem is coupled to a part in an integral form, thereby minimizing the amount of protrusion and an image is implemented in a distorted form, and advancing the quality of a product. The emblem structure includes a base layer, an image layer disposed on an outer surface of the base layer or to be spaced apart from the outer surface, and a transparent layer deposited on the base layer to cover the image layer. The transparent layer is configured such that light is transmitted and refracted and that the light reflected by the base layer and the image layer is lost, thereby improving visual recognition of the image layer.

The present disclosure relates to a decoration element comprising a light reflective layer; and a light absorbing layer provided on the light reflective layer, wherein the light reflective layer has surface resistance of 20 ohm/square or less.

An optical imaging film includes: a focusing layer, having two or more focusing structures; and a graphic layer, having two or more sub-graphics, and at least part of the sub-graphics are configured as a partial pattern of a preset graphic. The focusing layer is adapted to the graphic layer, and the focusing structures are provided corresponding to the sub-graphics, such that the optical imaging film presents an image of the preset graphic with a magnifying effect. The graphic layer of the optical imaging film includes a plurality of sub-graphics, and each of the plurality of the sub-graphics interacts with the corresponding focusing structure to form an image with a magnifying effect. Therefore, the sub-graphic is relatively large, thereby increasing the size of the images. That is, the optical imaging film can increase the magnification of the preset graphic.

A decoration element including: a color developing layer including a light reflective layer and a light absorbing layer provided on the light reflective layer; and a substrate provided on a surface of the color developing layer. The substrate comprises a pattern layer, and the light absorbing layer comprises an aluminum oxynitride (Al.sub.aO.sub.bN.sub.c).

An optical device includes an array of lenses and a plurality of segments disposed under the array of lenses. The plurality of segments corresponds to a plurality of images. Upon tilting the device at different viewing angle, the array of lenses presents images sequentially. In some examples, individual ones of the segments can comprise specular reflecting, transparent, diffusely reflecting, and/or diffusely transmissive features. In some examples, individual ones of the segments can comprise transparent and non-transparent regions. The images can produce one or more optical effects.
