Among the several known techniques described above, various techniques for illuminating components such as a light-emitting diode (LED) or a luminescent panel for backlights required for a keyboard and keyboard construction thereof are disclosed, although these known techniques are Similar, but there is still a difference in the assembly and disposition of the illuminating elements' so that the performance in the spatial form is not the same; however, among the above known techniques, the illuminating readings are all - independent components' Moreover, it is necessary to assemble the components of the keyboard in accordance with the design of the remaining components of the keyboard. The present invention is directed to providing an illuminated keyboard with a simple structure. In order to achieve the above purpose, the hair duck integrates the button circuit and the light-emitting layer into a kind of light-emitting circuit board, which can eliminate the illuminating component armor and further achieve the effect of the simplification structure. According to a preferred embodiment of the present invention, the button line and the illuminating layer are soft, wherein the illuminating light (5) ectroLumi ent, EL) material, and the plastic wiring of the button line. In another preferred embodiment of the present invention, a surface of an electroluminescent panel can be covered with a transparent light to form a light-emitting circuit handle integrated with a button line and a light-emitting layer. _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ There is an elastic body 12 and a suspension mechanism. The suspension mechanism 13 of the I3' is composed of two first brackets 131 and a second bracket 132 which are mutually overlapped. The bottom end of the second bracket 132 is engaged with the hook portion (1) of the wire, and the end of the second bracket 132 is detachably connected to the bottom surface of the keycap n (see "Fig. 2"), by means of a suspension mechanism* The B branch has a keycap 11 and an elastic body 12. Between the bottom plate 10 and the elastic body 12, there is also a light-emitting circuit board 40 integrated with a button line and an illuminant. The button circuit can be a soft plastic film switch, which is composed of three plastic films. 21 is an insulating film with a hole of 21 ,, and a preferred embodiment of the lowermost plastic film is composed of a -recorded (four) f-excited light plate (EL plate) 22 and a lower layer of the surface of the surface, which is composed of a key line 221, and the uppermost layer The surface of the plastic film 23 is formed with an upper-layer button line 23 in which the electro-excitation board is used to generate a desired backlight, and in the normal state, the upper button line 2:31 and the lower layer button line 221 are in the hole 21〇. They are separated from each other but are not in contact with each other... The key end 11 of the elastomer 12 is depressed. The bottom end 121 of the elastomer 12 forces the upper button line 231 and the lower button line 221 to contact each other, and then generates a telecommunication signal in accordance with the circuit design of the keyboard. After the external force/distraction, the keycap u can be pushed back to the normal position due to the restoring force of the elastic body 12. > Elastomer 12 is preferably permeable to light' and keycap u can be light transmissive or opaque: the right 疋 keycap 11 is opaque, then the symbol on it 11〇 can be printed for light transmission or directly printed with luminescent materials (such as fluorescent paint), if the keycap is transparent, then the symbol 110 on the surface will not shine or Light-transmissive design for identifiable effects. The uppermost layer of Na Na 23 can be turned over so that the electrically activated panel 22 can transmit the backlight required for the entire keyboard, while another feasible embodiment of the uppermost layer of adhesive film 23 is opaque. ❸t 'only the position of the upper button line 231 is transparent, so that the light emitted by the electroluminescent plate (EL plate) 22 can be irradiated upward through the hole 2 i to below the key cap ii to produce a non-comprehensive backlight. . In another preferred embodiment of FIG. 3, it is provided between the light-emitting circuit board 40 and the elastic body 12 that the touch panel 3 〇 ' is a neon 3 () convertible light-emitting panel (el The light emitted by the board is evenly directed to the entire keyboard to provide a more uniform backlight; and another possible embodiment is shown in Figure 4, in which a 1320901 The bridge plate 60 is used to carry the suspension mechanism i3. The bridge plate 6 is disposed on the keycap 11 and the light-emitting circuit board. 40% of the bridge plate 60 is preferably made of a light-transmissive material. Designed to be the same as the average optical power of the homogenizing plate 30, and in FIG. 5, another possible preferred embodiment is disclosed, in which the light-emitting circuit 'plate 4' and the elastic body 12 are further An opaque mask 5 is provided. The mask 50 has a perforation S1 only at a position corresponding to the upper button line 231 so that the light emitted by the electro-optical panel 22 can pass through the hole 21 and be perforated. 51 is illuminated upwards under the keycap u to produce a non-comprehensive backlight (see "Figure 6"). In the foregoing embodiments of the present invention, the electroluminescent plate (EL plate) 22 can be a soft type of plastic or a substrate (± element can also be a hard electric excitation of a substrate made of a glass plate). Light this board) 22. The above is only the preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. That is, the equivalent changes and the repairs according to the content of the patent application scope of the present invention are the technical scope of the present invention.
