[Prior Art] At present, the operation buttons of electronic products are generally equipped with a backlight function, that is, when the button is operated, the button will emit light, so that the user can correctly press the button to be operated, especially in the situation of insufficient ambient light. . Please refer to Figure 1 for a front perspective view of the key structure of the current electronic product. The button structure 1 in Fig. 1 includes a plurality of button bodies 11 and a plurality of light emitting diode (LED) lamps 12. The LED lamp 12 is configured to cooperate with the additional functions of the current electronic device. For example, in the case of a mobile phone, when the phone is dialed or operated at night, the keyboard structure automatically lights up to facilitate the user's operation, and the above light is from Backlight source LED light 12. The backlight source described above is simple to set up, and it can be clearly seen from Fig. 1 that the LED lamps 12 of the button structure 1 are distributed between the plurality of button bodies 11. However, such a backlight source configuration method has a characteristic of uneven illumination effect, which is caused by the fact that the light diverging by each of the LED lamps 12 gradually decreases with the divergence distance. Although such a backlight setting has achieved the effect of illumination, the overall feeling is that the keyboard light is uneven and affects the visual perception. 6 1362672 _ 'October 21, 100 Correction Replacement Pages A number of combined backlight modules have emerged to replace the simple LED backlight source. In the backlight module, the main function of the light guide plate is to guide the light direction to improve the brightness of the panel and control the brightness uniformity. Please refer to FIG. 2, which is a schematic view for explaining a light guiding device of the prior art. As shown in FIG. 2, the light source 21 is located on the side surface of the light guide plate 22. The light emitted by the light source 21 enters the light guide plate 22 from the side of the light guide plate 22, and the light incident on the light guide plate 22 is repeatedly reflected in the light guide plate 22, and is directed toward The incident light travels in the opposite direction. When the light is reflected, part of the light is scattered by the fine pattern 23 of the light guide plate, and then emitted from the surface of the light guide plate 22 into an illumination source of the liquid crystal panel, which can be formed by screen printing or etching process. Pattern 23. Please refer to FIG. 3, which is a schematic diagram for explaining the application of the light guiding device in a mobile phone in the prior art. When the light guide plate is applied to a button device of a portable electronic device such as a mobile phone, on the side of the light guide plate 22 having the pattern 23, a film 33 is attached for attaching a dot sheet. 34. Since the contact patch surface 341 has a viscous material, the metal dome 35 can be adhered to the printed circuit board (PCB) 36. Such a layer-by-layer manufacturing method is not only time-consuming and labor-intensive, but also makes it difficult to achieve the purpose of thinning the mobile phone. Therefore, in order to effectively reduce the process and achieve cost reduction, the present invention applies the combined backlight module to any keyboard or button device that needs to be illuminated, and can be applied to, for example, a mobile phone, a personal digital assistant (Personal Digital Assistant). , PDA)' Global Positioning System (Global 1362672 October 21, 100 revised replacement page
