Led) backlight mode. In the sixth embodiment, a single-structure electroluminescent system shown in U.S. Patent No. 5,856,29, discloses an electroluminescent lamp comprising a rear electrode layer, a dielectric layer. (Dielectric • layer) 15 Electroluminescent layer (Eiectr〇iuminescent iayer) 14th month of the translucent electrode 13, a protection ^ a 〇 Ver) 12, a bus bar n. In use, the back electrode layer 16 is first printed on a substrate 17 (such as clothes) composed of a silk fabric. Then, the dielectric layer 15, the electroluminescent layer 14 and the front electrode layer 13' are sequentially printed. A conductive line 11 is printed on the front electrode layer 13, and finally the protective layer 12 is printed thereon, and the protective layer 12 is adhered to the substrate 17. However, since the electroluminescent lamp is printed directly on the final product (such as clothes), if the electroluminescent system is directly printed on the electronic product in a similar manner, the electronic product may not be suitable for use in printing 5 M305532 Brushing 咼 咼 temperature, baking and other environments and equipment, will cause great trouble to the production. It is therefore necessary to export the electroluminescent system as a separate product and then to the electronic product. Another type of electroluminescent lamp is described in the seventh and eighth figures.

The electroluminescent lamp is printed by ink as a whole, so its strength is poor, and it is easy to break when subjected to external force stretching day. On the other hand, when the electroluminescent lamp is applied to a mobile phone diagram, it is not shown. When it is above, it is contacted with the button on the mobile phone through the outer surface of the first outer casing layer 1〇4, and the first outer casing layer 104 is formed by printing a layer of insulating ink of 6 M305532, the strength of which is poor, the virtual period It is easy to break after use. If the Ding Dong is long, the electric light is driven by the alternating current to drive the electroluminescent lamp. The lower-time current will flow in the opposite direction. This periodic undulation causes the electroluminescent lamp to emit some noise. When applied to mobile power, it will affect the comfort and quality of the call. " Creator feels The lack of improvement can be improved, and the research is devoted to the use of academic theory, and finally the design is reasonable and effective to improve the above-mentioned creations.
