Abstract:
A housing for an electronic device includes a metal substrate and a ceramic coating directly formed on at least portions of the substrate, the coated portions of the substrate having a rough surface. A method for fabricating the housing comprises roughening predetermined portions of the substrate; thermally spraying a ceramic coating on the roughened portions of the substrate, fixing the substrate on a tool having cold water circularly running there within during the thermal spraying; and grinding and polishing the ceramic coating.
Abstract:
A metal housing (10) includes a base (110) and an outer layer (120). The base is made of a thin metal plate. The outer layer includes a plurality of first sections (121) and second sections (122). The material of the first sections is different from that of the second sections. The first sections and the second sections are arranged on the base in an interleaving manner.
Abstract:
An exemplary housing of electronic device includes a metallic main body and a metallic three-dimensional weaving member formed on at least a part of a surface of the metallic main body. An electronic device using the housing is also provided. The housing of the electronic device has a textured touching feeling.
Abstract:
The present invention provides a spacer placed between a top substrate and a bottom substrate for a field emission display device. The spacer comprises at least two insulating layers for electrical insulation; and at least one metal layer sandwiched between the insulating layers, wherein the metal layer has plural apertures for electrons passing therethrough and disturbing pathway of electrons as the electrons impact the apertures.
Abstract:
A method for making a device housing comprises: providing a metal substrate; etching grooves on a portion of the surface of the metal substrate; forming a metallic coating on the surface of the metal substrate and in the grooves; and removing the metallic coating formed on the surface of the metal substrate not comprising the grooves. A device housing made by the method is also described there.
Abstract:
A method to fabricate a pattern on a housing, includes following steps: placing a film having a first lightproof area and a first light-transmissible area on a housing having light-sensitive inks formed in surface; radiating light on the film and light passing through the light-transmissible area and solidifying the light-sensitive inks; removing the film from the housing and cleaning the un-solidified light-sensitive inks; wiredrawing first wires in the housing and forming first wires in exposed area correspondingly; covering part of the first wires and wiredrawing second wires, the second wires crosses with part of the first wires.
Abstract:
The present invention provides an electron amplification plate placed between a first substrate and a second substrate of a field emission display device. The electron amplification plate comprises at least two insulating layers for electrical insulation; and at least one conductive electrode layer having plural apertures, wherein the conductive electrode layer is sandwiched between the insulating layers. The surface of the inner wall of the apertures is coated with an electron-amplifying material for multiplying the quantity of electrons as the surface is impacted. The inner wall of each aperture comprises an upper concave wall and a lower concave wall, and the lower concave wall is used for collecting electrons, and the upper concave wall is used for focusing electrons. Thereby, the electron beam emitted from the emitters can be effectively amplified, and color purity of the field emission display device is high.
