Abstract: The present invention discloses a method to manufacture a keycap for keys of a keyboard, including: providing a top fabric layer and a molding film disposed beneath the top fabric layer; molding the molding film and the top fabric layer to form a film structure having an inner surface; and providing a keycap body having an upper surface, wherein the outline of the upper surface matches with that of the inner surface to form the keycap. In the present invention, the keycap is formed using the film structure and the keycap body by plastic injection or adhesion agent, the keycap is further manufactured as keys, and a symbol is engraved on the upper surface of the film structure by laser. Because the backlit device's light transmits through the keycap, users can recognize the symbols on the keys.

Abstract: The present invention discloses a film structure for a keycap, including a molding film presenting a shape conforming with the outline of the upper surface outline of the keycap; and a polyurethane (PU) layer disposing on the molding film and engraved a symbol thereon, wherein the symbol indicates a specific keycap. In the present invention, the problems with the symbols of the keycaps becoming dislocated, yellowed and deformed when the keycaps are manufactured with currently available techniques can be overcome, and users can clearly see the symbols on a backlit keyboard.

Abstract: The present invention discloses a keycap for keys of a keyboard device, wherein the keys are configured on the keyboard, and the keycap is configured on a key body. The keycap includes: a top fabric layer, a keycap body including an upper surface outline, and a molding film. The top fabric layer is used for engraving to have a symbol thereon to transmit light therethrough, wherein each symbol indicates a specific keycap. The molding film is disposed between the top fabric layer and the keycap body to render the top fabric layer in a specific shape matching with the upper surface outline. In the present invention, the problems with the symbols of the keycaps becoming dislocated, yellowed and deformed when the keycaps are manufactured with currently available techniques can be overcome, and users can clearly see the symbols on a backlit keyboard.
