20080218991 | LIGHT-GUIDING METHOD OF LIGHT-GUIDING PLATE AND KEY PAD ASSEMBLY USING THE LIGHT-GUIDING PLATE - A key pad assembly includes a printed circuit board, a first elastic layer, a second elastic layer, a light-shielding layer, a keycap group, a light-emitting element and a light-shielding piece. The second elastic layer has a light-guiding plate thereon. The light-guiding plate has a chain-like light-shielding structure. The light-shielding structure is constituted of a plurality of penetrating holes with neighboring ones arranged alternatively and divides the light-guiding plate into two light-guiding sections. When the lights with different colors are introduced from the outside of the two light-guiding sections into the light-guiding plate, and the light of either light-guiding section passes through the light-shielding structure, the intensity of the light passing through the penetrating hole is so reduced that it cannot achieve the other light-guiding section, thereby to avoid the mutual interference and mixing of the lights of the two light-guiding sections. | 09-11-2008 |
20090166931 | PROCESS FOR MANUFACTURING KEYPAD MODULES OF NON-BACKLIGHTED PANELS - A manufacturing process for a keypad module includes the steps of: providing an opaque layer, one side of the opaque layer having symbol regions; providing a mold formed thereon with a planar recession and a plurality of pits for forming keys; injecting a gel-like ultraviolet curable resin into the planar recession and pits of the mold; adhering the surface of the opaque layer having the symbol regions on the planar recession of the mold so as to contact the ultraviolet curable resin; irradiating the mold with an ultraviolet light so as to cure the ultraviolet curable resin; and taking out the opaque layer and the cured ultraviolet curable resin to obtain a keypad module. | 07-02-2009 |
20090167689 | KEYPAD MODULE OF NON-BACKLIGHT PANEL AND PANEL ASSEMBLY OF THE SAME - A keypad module includes a non-backlight layer made of an opaque thin sheet, and a key layer made of an ultraviolet curable resin. One surface of the non-backlight layer is provided thereon with a recognition region. The key layer has a base portion and a plurality of pressing portions protruding from the base portion. The base portion is overlapped with and bonded to the surface of the non-backlight layer on which the recognition region is provided. Each of the pressing portions is arranged to correspond to the recognition region. The panel further includes a telecommunication module located below the keypad module. | 07-02-2009 |
20090173605 | KEYCAP FOR GUIDING LIGHT LATERALLY AND KEYPAD PANEL HAVING THE SAME - A keycap is made of a light-transmitting material. The bottom of the keycap has a light-entering surface. A light-exiting surface extends from one side of the light-entering surface and intersects therewith. A connecting surface is formed between the light-entering surface and the light-exiting surface. The connecting surface is covered by a light-shielding layer. A light-reflecting surface is formed in the light-shielding layer. The light is introduced from the light-entering surface and reflected by the reflecting surface so as to project toward the light-exiting surface. The keypad panel is constituted of the above-mentioned keycap. | 07-09-2009 |
20090173609 | PROCESS FOR KEYCAPS CAPABLE OF GUIDING LIGHT LATERALLY - A process for keycaps includes the steps of: providing a light-transmitting material; making the light-transmitting material into a keycap body, the keycap body having a light-entering surface, one side of the light-entering surface extending to form a light-exiting surface intersecting with the light-entering surface, a connecting surface being formed between the light-entering surface and the light-exiting surface; and coating a light-shielding layer on the connecting surface to form a light-reflecting surface in the light-shielding layer. Via the above process, a keycap that guides light laterally can be obtained. | 07-09-2009 |
20090173713 | Method for Manufacturing Metallic Panel Having Multilayer Arrays Of Micropores - A method for manufacturing a metallic panel having multilayer arrays of micropores includes the steps of: preparing a metallic thin plate first; forming a plurality of micropores and hollowed portions on the metallic thin plate with the hollowed portion forming a key body; arranging the plurality of micropores to form a pattern on the surface of the key body; and cutting the metallic thin plate to form a metallic panel of a predetermined shape. Then, a multilayer backlight module is arranged on one side surface of the metallic panel via a hot pressing or adhering process. Finally, a telecommunication module is adhered on one side surface of the backlight module. In this way, the metallic panel having multilayer arrays of micropores can be completed. | 07-09-2009 |
20090175440 | Metallic Panel Assembly Having Multilayer Arrays Of Micropores - A metallic panel assembly having multilayer arrays of micropores includes a backlight module and a panel body. The backlight module is constituted of a first and a second light-guiding plate. First and second light-guiding microstructures are provided on the first and second light-guiding plates. A first and a second set of light-emitting units are disposed on one end of the first and second light-guiding plates, respectively. A first and a second shielding unit are disposed on the first and second light-guiding plates and the first and second sets of light-emitting units respectively. The panel body is disposed on one side surface of the first light-guiding plate. The panel body has thereon a plurality of hollowed portions with the hollowed portions encircling a key body. The key body has thereon a plurality of micropores. The plurality of micropores is arranged to form a pattern of each key body. When the first or second set of light-emitting units are lighted up, the light enters one side of the first or second light-guiding plate. The light is reflected by the first or second light-guiding microstructures on the corresponding key panel, so that the user can see the position of each key clearly. | 07-09-2009 |
20090241338 | METHOD OF MANUFACTURING NON-BACKLIGHTED ILLUMINATING KEYPAD - A method of manufacturing non-backlighted illuminating keypad includes preparing a transparent plastic thin plate; forming a plurality of keycaps on a surface the plastic thin plate; forming a light gathering layer on another surface of the plastic thin plate opposite to the keycaps; attaching the plastic thin plate onto an electronic ink layer; and attaching an first elastic layer on the electronic ink layer. | 10-01-2009 |
20090242368 | NON-BACKLIGHTED ILLUMINATING KEYPAD - A non-backlighted illuminating keypad includes a keypad panel, a light gathering layer, an electronic ink layer, a first elastic layer and a switch board. The keypad panel includes a carrier and a plurality of keycaps arranged on the carrier. The light gathering layer is arranged on a bottom surface of the keypad panel and located corresponding to the keycaps. The electronic ink layer is arranged on a bottom surface of the light gathering layer. The first elastic layer is arranged on a bottom surface of the electronic ink layer and comprises a plurality of protrusion portions respectively corresponding to the keycaps.
