Various components of an electronic device housing and methods for their assembly are disclosed. The housing can be formed by assembling and connecting two or more different sections together. The sections of the housing may be coupled together using one or more coupling members. The coupling members may be formed using a two-shot molding process in which the first shot forms a structural portion of the coupling members, and the second shot forms cosmetic portions of the coupling members.

The present invention discloses a decorative sheet, an electronic apparatus cover plate and an electronic apparatus. The decorative sheet is used for forming a three-dimensional image to represent a three-dimensional material object. The decorative sheet comprises a transparent protective layer, a graph-text structure layer and a reflective layer; the graph-text structure layer and the reflective layer are located on a same side of the transparent protective layer; the graph-text structure layer comprises a number of graph-text sub-blocks which form the three-dimensional image and each of which comprises a micro-structure that represents corresponding lightness of the three-dimensional material object. The lightness of light rays emitted by each graph-text sub-block comprising the micro-structure is different, and thus a change of lightness is produced among the graph-text sub-blocks. By using the lightness change among the graph-text sub-blocks to represent the lightness change of the three-dimensional material object in a natural state, the graphs and text displayed on the graph-text structure layer are enabled to have a three-dimensional effect.

A glass cover board structure comprises a top cover and a bottom plate, wherein, the top cover comprises a top plate and a plurality of side wall plates used in surrounding the top plate, the side wall plates at least comprise end surfaces, the bottom plate comprises a contacting area, and the end surfaces are adhesive to the contacting area. In the present invention, design a traditional planar glass cover board into a concave-shape glass cover board, remove assembling gaps to a rear cover of an electronic product when assembling the rear cover, and assemble the gaps at an invisible area after processing printing art to the glass cover board to achieve objects of raising appearing of electronic product.

An electronic device may have transparent housing structures such as walls formed of glass or sapphire. Housing structures such as transparent housing structures may have a colored coating. The colored coating may include an absorptive layer and a metal layer. The coating may exhibit a color that can be adjusted by adjusting the thickness of the thin absorptive layer. A colored layer such as a layer of colored polymer may be incorporated into the colored coating to further adjust the color of the coating. The colored coating may be formed on an inner or outer housing structure surface. The surface may have a texture to provide the coating with a matte appearance. When formed on an outer surface, a diamond-like carbon layer may protect the colored coating. When formed on an inner surface, a passivation layer may be used to prevent oxidation of the metal layer.

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.

An electronic device may have a housing. The device may include metal structures such as a metal member forming a portion of the housing, a portion of a strap, or other portions of the device. A gold-containing coating such as a layer of elemental gold or a gold alloy may cover the metal member to provide the metal member with a gold appearance or other desired appearance. To protect the metal member and the gold-containing coating, the metal member and gold-containing coating may be covered with a protective coating layer such as an organic protective layer. The organic protective layer may have a fluoropolymer layer with thiol coupling groups to promote adhesion to the gold-containing layer or may contain a polymer layer with silane and thiol coupling groups that serves as an adhesion promotion layer for an overlapping fluoropolymer layer with silane coupling groups.

Textured cover assemblies for electronic devices are disclosed. The textured cover assemblies may provide a combination of optical and tactile properties to the electronic devices. In some cases, a textured cover assembly may be provided over decorative coating.

A display device for vehicle interiors includes a screen having an active front screen surface comprising a main area and a marginal area, and a decorative layer covering the marginal area and not covering the main area. The decorative layer is configured such that in a non-switched-on state of the screen in the marginal area, the marginal area is not visible through the decorative layer In a switched-on state of the marginal area, light emitted from the marginal area is visible through the decorative layer. Furthermore, a method of manufacturing such a display device is provided.

The present disclosure is drawn to covers for electronic devices. In one example, a cover for an electronic device can include an enclosure with a light metal substrate with an opening therethrough, and a first protective coating covering the light metal substrate. A second protective coating is on the first protective coating, and a chamfered edge is present along the opening where the chamfer cuts through the first protective coating and the second protective coating to expose the light metal substrate at the chamfered edge. In one example, a transparent passivation layer is included along the chamfered edge.

An electronic device may include electrical components and other components mounted within an interior of a housing. The device may have a display on a front face of the device and may have a glass layer that forms part of the housing on a rear face of the device. The glass layer may be provided with regions having different appearances. The regions may be textured, may have coatings such as thin-film interference filter coatings formed from stacks of dielectric material having alternating indices of refraction, may have metal coating layers, and/or may have ink coating layers. Textured surfaces may be formed on thin glass layers and polymer films that are coupled to the glass layer. A glass layer may be formed from a pair of coupled glass layers. The coupled layers may have one or more recesses or other structures to visually distinguish different regions of the glass layer.
