20080223702 | KEYPAD ASSEMBLY - A compact keypad structure includes keypad panel with smooth face, matted face or patterned layer. The keypad structure includes a flexible printed circuit board, an illumination layer, a resilient layer and a keypad layer in bottom-up order. The illumination layer includes an illumination plate to illuminate the bottom of the resilient body when the keypad is operated. Therefore, the surface of the keypad has transparent effect for display. The first carrier and the second carrier of the keypad layer, and the resilient body of the resilient layer are deformed when external force is applied to the surface of the keypad. A protrusion is pressed against the surface of the illumination plate and a metal dome on another face of the illumination plate is deformed and pressed against the flexible printed circuit board. The metal dome is in contact with contact of the flexible printed circuit board to output an operation signal. | 09-18-2008 |
20080224347 | METHOD FOR MANUFACTURING KEYPAD - In a method for manufacturing compact keypad, a first molding die with bottom surface of smooth face, matted face or patterned layer is prepared. Colloid is injected into the first molding die and a first carrier covers the surface of the colloid. A rolling wheel presses the first carrier and the colloid evenly into the first molding die. The colloid is cured by UV light to form a keypad layer attached on the first carrier. A background color layer, a functional color layer and a textual color layer are formed on the first carrier. A second carrier is prepared and a reflection layer is printed on the surface of the second carrier. The second carrier and silicon rubber are placed into a second molding die and thermally pressed therein to form a resilient layer. The resilient layer is adhered with the keypad layer to form the keypad panel. | 09-18-2008 |
20080224359 | MANUFACTURING METHOD OF THIN KEYPAD ASSEMBLY - In a method of manufacturing a thin keypad of a keypad panel having a smooth surface, a mist surface or a lines layer, the method includes the steps of: preparing a mold with an internal bottom surface of a coarse surface, a smooth surface or a lines surface; applying an adhesive into the mold and coating a carrier onto the surface of the adhesive; rolling the surface of the carrier by a roller to level the adhesive in the mold; performing a ultraviolet projection to cure the adhesive to form a keypad layer on the carrier; filming a ground color layer, a function color layer and a font color layer sequentially on the carrier as the background of the keypad panel; and hot pressing and combining the keypad layer and silicon to produce the keypad panel. | 09-18-2008 |
20090113695 | METHOD FOR MANUFACTURING METALLIC KEYPAD HAVING RIPPLE LUSTER - A method for manufacturing a metallic keypad has a ripple luster. First, a metallic thin plate is prepared. The metallic thin plate is subjected to an etching process, thereby forming a plurality of hollowed portions on the metallic thin plate. The hollowed portions are used to define a pressing region for the key and icons for the surface of the pressing region. The metallic thin plate is cut to form a metallic keypad having a predetermined shape. Then, after an electroplated layer is coated on the surface of the metallic keypad, a layer of protective film is adhered on the non-electroplated surface of the metallic keypad. Finally, the metallic keypad is disposed into a mold. A plastic material is injected into the mold, so that the plastic material forms a pattern layer. Finally, an adhesive layer is applied on the non-electroplated surface of the metallic keypad. The elastic layer having a plurality of protrusions is adhered on the surface of the adhesive layer. Via the above steps, the metallic keypad having a ripple luster is manufactured completely. | 05-07-2009 |
20090114334 | METHOD FOR MANUFACTURING METALLIC PANEL HAVING RIPPLE LUSTER - A method for manufacturing a metallic keypad panel having a ripple luster. First, a metallic thin plate is prepared. The metallic thin plate is subjected to an etching process, thereby forming a plurality of hollowed portions on the metallic thin plate. The hollowed portions are used to define a pressing region for the keypad and icons for the surface of the pressing region. The metallic thin plate is cut to form a metallic keypad panel having a predetermined shape. An electroplated layer is coated on the surface of the metallic keypad panel. Then, a layer of protective film is adhered on one side surface of the metallic keypad panel. The metallic keypad panel is disposed into a transparent mold. After an ultraviolet curable resin is injected into the mold, a light source illuminates the transparent mold to cure the ultraviolet curable resin in the mold to form a pattern layer. Finally, after the protective film on the other surface of the metallic keypad panel is peeled off, an adhesive layer is applied on the other surface of the metallic keypad panel. An elastic layer having a plurality of protrusions is adhered on the surface of the adhesive layer. Via the above steps, the metallic keypad panel is manufactured completely. | 05-07-2009 |
20090115640 | METALLIC KEYPAD ASSEMBLY HAVING RIPPLE LUSTER - A metallic keypad assembly having a ripple luster includes an elastic layer, an adhesive layer, a metallic keypad, an electroplated layer and a pattern layer. The elastic layer has a carrier. The carrier is provided thereon with a plurality of protrusions. The adhesive layer is provided on one side surface of the carrier. The metallic keypad is provided on one side surface of the adhesive layer and has a thin plate thereon. The plate is provided thereon with a first hollowed portion and a second hollowed portion. The first hollowed portion defines a pressing region of a key, 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 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, the pattern layer generates a reflective effect of a ripple luster. | 05-07-2009 |
20090126186 | METHOD OF MANUFACTURING METAL KEYPAD PANEL WITH MICROPORE ARRAY - In a method of manufacturing a metal keypad panel with a micropore array, a metal laminate is prepared and etched to form micropores on the metal laminate, and a filling is coated on a surface of the metal laminate and permeated into the micropores. After the metal laminate is punched to form a metal keypad panel in a predetermined shape, the metal keypad panel is put into a mold. After a plastic material is injected into the mold, a pattern layer is formed on a side of the metal keypad panel, and then a backlight module is attached onto another side of the metal keypad panel. The backlight module has patterns, and the shape of the patterns is formed by arranging light guide microstructures. Finally, an electric signal module is attached onto a side of the backlight module to complete manufacturing the metal keypad panel. | 05-21-2009 |
