  • Publication number: 20090305007
    Abstract: The invention discloses a shell for portable electronic devices which includes a main body and an opaque ink layer. The main body is made of translucent material and includes an outer surface and an inner surface opposite to the outer surface. The opaque ink layer is coated on the inner surface of the main body except for a design area on the inner surface of the main body. Through masking, the design area may incorporate any desired decorative pattern such as a logo, a call id pattern, a message prompt pattern, a charging pattern or some other design. The design area is an area surrounded by the opaque ink layer and the inner surface is exposed through the design area. The invention also discloses a method for making the shell.
