Abstract
A method for fabricating a keyboard covering film is provided. The method includes steps of: coating a transparent plastic material on an upper surface of a fabric layer before the transparent plastic material is cured; treating the fabric layer and the transparent plastic material by a hot press process to cure the transparent plastic material to form a transparent layer and to make the transparent layer and the fabric layer jointly form a number of keycap receiving sections; forming a mask layer on a lower surface of the fabric layer; removing a portion of the mask layer and a portion of the fabric layer located within each of the keycap receiving sections to form a number of hollow patterns.
