Field of the Invention The present invention relates to a keyboard assembly and a portable electronic device having the keyboard assembly, and more particularly to an illuminated keyboard assembly and a portable electronic device having (four) illumination (four) components . [Prior Art] With the continuous updating and development of technology, portable electronic devices such as mobile phones or personal digital assistants (PDAs) have gradually become a necessity for people to live happily. In order to meet the needs of the constant communication, portable electronic devices with illuminated keyboards have become a popular trend. Referring to Figures 1 and 2', a mobile phone (10) includes a food item (8), a touch switch 102, a printed circuit board 1〇3, and a housing (10). The disk unit ΗΠ is placed on the touch switch 1〇2 for pressing the touch switch 1〇2. The touch switch 102 is disposed on the printed circuit board 〇3. The outer casing (10) = has a top end (not shown) and an opposite bottom end _. The casing 1 (10) is used to hold the keyboard assembly 101, the touch switch 1〇2, and the printed circuit board (8) on the basin. The keyboard assembly 101 includes a plurality of keys 1〇11, a light-emitting component/(4), and a guide plate 1GU. The button 1G11 is mounted on the light guide plate HH3. The bottom end W1 of the outer casing (10) is disposed, and the light emitted from the optical assembly (4) is conducted to the respective buttons (8) 1 by the light guide plate 1013 to illuminate the button 1011. Since the outer casing HM is provided with a light permeable characteristic and the light emitting component is adjacent to the bottom end of the outer casing, the light leakage at the bottom end 1041 is inevitably caused, especially when the mobile phone is used during the night 200921732. Stinging. SUMMARY OF THE INVENTION In view of this, it is necessary to provide a keyboard assembly for preventing leakage. A keyboard assembly, which is suitable for a plurality of buttons, a light guide plate, the keyboard assembly includes a plurality of light guide plates, the light assembly is adjacent to the second member: the button is mounted on the second button; the shielding layer is disposed on the button and the light guide plate Between, in order to cover the components & out of the light outside the button area. - Portable electronic device with - keyboard assembly, package: =, keyboard assembly 'The keyboard assembly includes a plurality of two, the hairpin is adjacent to the guide button (4) is set at the end of the light guide plate ... And aligning with the light guide plate and β 'the concealer layer is disposed on the button 盥 guide plate in each button section ′ in order to occlude the illuminating group μ ΓΓΓ technology, the (four) saki (four) - silk layer to shield = the first line The utility model effectively solves the problem that the light-emitting component is located at each button=external light leakage, and avoids the use of the portable electronic device at night to attract glare, thereby enhancing the user's use of the portable electronic device and comfort. The preferred embodiment of the present invention discloses a keyboard assembly for a portable electronic device, which is suitable for portable electronic devices such as a wal digital assitant (PDA). 200921732 Referring to ® 3, ® 4 and ® 5, a preferred embodiment of the keyboard assembly of the present invention is illustrated by the keyboard assembly 20 of the mobile telephone 200. The mobile phone 200 includes a keyboard assembly 2 and a body %. The keyboard assembly 20 is mounted on the body 30. The keyboard assembly 20 includes a plurality of buttons 2, a shielding layer 2, a light guide plate 203, and two light emitting components 204. The button 2〇1 is mounted on the light guide plate 2〇3. The shielding layer 202 is disposed between the button 201 and the light guide plate 2〇3, so as to cover the light between the button 201 and the light-emitting component 2(4) to the inner surface of the casing corresponding to the light-emitting component 2〇4 (not shown) Light on the display). The light-emitting assembly 2〇4 is disposed adjacent to the light guide plate 2G3 and aligned with the light guide plate and the end portion. The button 201 includes a button cover 2〇u and a pressing body 2〇12. The button cover 20H can be integrated with the pressing body by means of bonding or the like. The pressing body is substantially a square body, and the end is protruded from - (4) for pressing a movable contact (not shown) on the corresponding touch switch, and the other end is a bonding surface 2014. The shielding layer 202 has opacity, and includes a main body portion and an extending portion 2022. I Haiyan (4) 2〇22 is formed by extending one end of the main body 2〇2. The main body portion 2〇21 is a rectangular film, and the plurality of through grooves (10) are opened on the basin by the button 20, so that the light from the light guide plate can be transmitted to the button by the through slot, and the light is blocked. The extension portion 22 is configured to block the light-emitting component: 4 to the light on the inner surface of the corresponding casing of the light-emitting assembly 204. The light guide plate 203 is made of a light-guiding material, which is substantially a rabbit body. The shape and size of the light guide plate 203 is substantially the same as the shape of the shielding layer 2Q2 and the thickness of the 200921732 inch. The plurality of key grooves 2 〇 3 are provided corresponding to the button 201, and the 苴p bucket, size and shape and the button are provided. The shape and size of 201 are substantially equivalent, and are used to partially accommodate the button 2〇. The light-emitting component 204 is a light-emitting diode disposed adjacent to the end of the light guide plate 2〇3 and electrically connected to a printed circuit board (not shown). Referring to FIG. 5 to FIG. 7 , when the keyboard assembly 2 is assembled, the first shielding layer 202 is attached to the light guide plate 2〇3, so that the through slot/2023 of the shielding layer 2〇2 is aligned with the button of the light guiding plate 2G3. Slot 2 () 31; However: after pressing the pressing surface 20U close to the light guide plate 2G3, the pressing body is sequentially placed in the keyway groove and the through groove; then the button cover is bonded to the pressing body 2012 The cover 2014 is formed to form the button 2〇1; finally, the light-emitting component 204 is adjacent to the end of the light guide plate 2G3, and is electrically connected to the printed circuit board 'A. The shielding layer 2G2 is located at the button 2Q1 and the light guide plate. The main body portion 2〇21 of the shielding layer 202 covers the light between the buttons 2〇1, and the extending portion 2022 blocks the light of the light-emitting element 2〇4 from being incident on the inner surface of the corresponding casing of the light-emitting element, so that the completion is completed. The assembly of the keyboard assembly 2 is completed. In use, the light emitted by the light-emitting component 204 is transmitted to the respective keys: 201 by the light guide plate 2 to illuminate the respective keys 2〇丨, and at the same time, the main body 2〇21 of the shielding layer 202 shields the light-emitting components 2〇4 from being conducted. To the light guide plate Μ] the light between the respective buttons 2〇1 and the light-emitting elements _ light incident on the inner surface of the casing corresponding to the light-emitting assembly 204. It can be understood that the extension portion 2022 of the shielding layer 202 can also be a separate/special film' and cover the light emitting assembly 204. 200921732 It can be understood that the extension portion 22 of the shielding layer 202 can also be attached to the inner surface of the corresponding casing of the light-emitting component 204. It can be understood that the extension portion 2〇22 of the shielding layer 2〇2 can also be omitted, and only the inner surface of the corresponding casing of the light-emitting component 204 is coated with an opaque paint film to shield the light-emitting component 204. Light rays on the inner surface of the casing corresponding to the light-emitting assembly 2〇4. The keyboard component 20 adopts the shielding layer 2〇2 to shield the light and the line located outside the area of each button 201, thereby effectively solving the problem of light leakage outside the area of each button 2〇1, which avoids the use of a mobile phone at night. The glare enhances the convenience and comfort of the user using the mobile phone. As mentioned above, the present invention complies with the invention patent requirements.
