Abstract
A metallic keypad panel assembly having a ripple luster includes a thin plate, a displaying layer, an elastic layer, an adhesive layer, a metallic keypad panel, an electroplated layer and a pattern layer. One side surface of the thin plate is printed with a film to form a displaying layer. The elastic layer is adhered on one side surface of the displaying layer and has a carrier thereon. One side surface of the carrier is provided thereon with a plurality of protrusions. The metallic keypad panel is disposed on one side surface of the thin plate and has a plate body thereon. The plate body is provided thereon with a first hollowed portion and a second hollowed portion. The first hollowed portion defines a pressing region of a keypad, and the second hollowed portion is set as an icon on the surface of the pressing region. The electroplated layer is provided on one side surface of the metallic keypad panel and penetrates into the first hollowed portion and the second hollowed portion. The pattern layer is provided on one side surface of the electroplated layer to seal and fill the first hollowed portion and the second hollowed portion. When external light illuminates the pattern layer of the metallic keypad panel, the pattern layer generates a reflective effect of a ripple luster.
