The plastic frame is combined with an inner surface of the metal frame, the plastic frame has an integrally formed structure. An electronic device having the composite frame structure and a method for manufacturing the composite frame structure are provided.

Abstract: A coated member, an electronic device, and a method for manufacturing the coated member are provided. The coated member comprises a substrate, a color layer formed on a surface of the substrate, and an interference layer formed on a surface of the color layer. A coordinate L* corresponding to a color space presented by the color layer in a CIE LAB color system is within a preset range. When the coordinates of L* are within the preset range, the color of the coated member may be the same or may be different from the color of the color layer. Light passes through the interference layer and then enters the color layer. The color layer reflects and refracts the light. The reflected light enters the interference layer. The interference layer interferes with the reflected light, so that the coated member appears to be a target color.
