Abstract:
A method of making a device cover, said method comprising:positioning a first insulating foil over a first surface of an electroluminescent foil to form a preliminary cover member; performing the preliminary cover member into a preselected shape; punching first holes through the preliminary cover member for passage of control keys therethrough and a second hole through the first insulating foil to expose a surface of the electroluminescent foil; placing the preliminary cover member into a mold of the preselected shape, the mold having bosses corresponding with the first holes and to the second hole; and injecting plastic into the mold and into contact with the preliminary cover member to form the device cover, the bosses providing holes through the plastic corresponding with the first and second holes so that when the mold is opened the first holes extend through the device cover and the second hole extends to the surface of the electroluminescent foil.
