As shown in the third figure (b is a number, a character, a special symbol, *, ·), and a direction symbol, the punching step is performed: the metal thin plate 1G is die-cut. Thereafter, a metal panel i having a predetermined shape is formed, as shown in the third figure (c, d). Steps of affixing the backlight module 2 (such as the fourth and fifth figures): the first light guide plate 21 and the second light guide plate 22 of the plate shape 7 200931294 are attached to one side of the metal panel 1, the first The light guide 21 and the second light guide plate 22 can be formed on the side of the metal panel 1 by hot pressing or adhesive bonding, and the pattern 14 having the corresponding button body 13 is pressed onto the first light guide plate 21 and the second light guide plate 22 . The first light guiding microstructure 211 and the second light guiding microstructure 221 are arranged in a staggered state corresponding to the button body 13. The first group of light-emitting units 23 and the second group of light-emitting units 24 are disposed at one end of the first light guide plate 21 and the second light guide plate 22, and the first group of light-emitting units 23 and the second group of light-emitting units 24 are disposed. The first concealed early element 25 and the first concealed early element 26' are disposed above the first shielding unit 25 and the second shielding unit 26 to shield the first group of the light emitting unit 23 or the second group of the light emitting unit 24 The resulting light 'avoids light from interfering with each other. Moreover, the first group of illumination elements 23 and the second group of illumination units 24 are a plurality of light-emitting diodes of the same or different colors. The first and second light guiding microstructures 211 and 221 are recessed in the first and second light guiding plates 21 and 22 or protruded from the first and second light guiding plates 21 and 22. Step 108, the telecommunications module 3 is pasted (as shown in the sixth figure): an electric module, and 3 is attached to one side of the backlight module 2, the telecommunication module 3 has a flexible printed circuit board The printed circuit board 31 is provided with a plurality of contact points 311, and each of the contact points 311 corresponds to a metal dome i2), and is disposed on the U-face of the circuit board 31 and the metal dome 32. The layer 33' is further provided with a convex portion on the side of the convex portion of the film layer 33. The convex portion 34 corresponds to the first and first light-emitting microstructures 211 and 221 on the first and second light guide plates 21 and 22. 8 200931294 Please refer to the fifth figure, which is a schematic diagram of the illumination of the backlight module of the present invention. As shown in the figure: under the circuit control (not shown) of the associated electronic device, the first group of illumination units 23 or When one of the second group of light-emitting units 24 is illuminated, the light 4 generated by the first group of light-emitting units 23 or the second group of light-emitting units 24 is entered by the first light guide plate 21 or the second light guide plate 22, the Light ray 4 to the first light guiding microstructure 211 or the second light guiding microstructure 22 折射 refracting the light 4 to the button body 13 The line 4 is then punched out by the plurality of micro-holes, so that the pattern 14 on the surface of the button body 13 can be displayed. When the first group of light-emitting units 23 or the second group of light-emitting units 24 are illuminated, the metal panel 1 The pattern 14 on the button body 13 having only a few columns or rows is displayed to facilitate the user to perform a video game or multimedia operation. When the first group of light emitting units 23 and the second group of light emitting units 24 are simultaneously illuminated At the time, the pattern 14 on the button body 13 of the column or rows on the metal panel 1 will present the same color ' while the other columns or rows exhibit another color. Or in the first group of illumination units 23 And the light of the third color group is mixed, and the light of the third color is generated 4. »月> The combination of the side view and the pressing action diagram is as shown in the figure: The surface of the button body 13 of the field panel 1 is pressed by an external force, so that the button body 13 is diamond-shaped, and the urging convex body 34 is pressed down to the film layer, so that The metal dome 2 is pressed in contact with the contact point 311 When the metal button face W is not subjected to an external force, the metal plate 200931294 is automatically raised back to the original state due to the elastic relationship between the gold panel 1 and the metal dome 32.
