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.

Abstract: In a method, a sapphire raw material is placed into the recess of a mold and melted by heating to infill the recess by capillary action to form a liquid film. A sapphire seed having a specific growing plane is moved to dip the growing plane into the liquid film, thus forming a solid-liquid interface. The sapphire seed is lifted up such that the liquid film is crystallized on the growing surface to form the sapphire substrate. Two surfaces of the sapphire substrate are first coarsely and then finely ground to reduce a thickness of the sapphire substrate. The two surfaces of the sapphire substrate are first coarsely and then finely polished to improve smoothness of the surfaces.
