Description of the Invention: [Technical Field] The present invention relates to an electroluminescent lamp and a combination thereof with a metal key sheet, and a method of manufacturing the same, and more particularly to a method that is not easily broken and is easy to be drilled to another An electroluminescent lamp on an electronic component and its combination with a metal keypad, and a method of manufacturing such an electroluminescent lamp. [Prior Art] With the popularization of high-tech products, electroluminescence technology that was used only in the driver's seat of aircraft has been widely used in consumer electronics such as mobile phones, pagers, and wireless phones. Personal digital assistants, remote controls and other products 'Because of the small size, light weight, low temperature, low power consumption, no flicker, uniform illumination, etc., the electroluminescent lamp has gradually replaced the traditional LED backlight. the way. Referring to the electroluminescent system of the single structure shown in the sixth figure of U.S. Patent No. 5,856,029, it is disclosed that an electroluminescent lamp comprises a rear electrode layer 16 and a dielectric layer (rear e ectrode 1 ayer) Dielectric layer 15 , an electroluminescent layer 14 , a translucent electrode 13 , a cover 12 , a bus bar 11 . In use, the back electrode layer 16 is first printed on a substrate π (such as clothes) composed of a silk fabric, and then the dielectric layer 15, the electroluminescent layer 14, and the front electrode layer 13 are sequentially printed, and then before A coil of conductive trace η is printed over the electrode layer 13, and the protective layer 12 is finally printed, and the protective layer 12 is bonded 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 1322636 The environment and equipment such as high temperature and baking during the brushing process 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 method of manufacturing an electroluminescent lamp is disclosed in the Chinese Patent Application No. 99125456.2 (corresponding to U.S. Patent No. 5,856,030 and U.S. Patent No. 6,270,834). 'The electroluminescent lamp is printed on a transfer release paper 1 〇 2, the electroluminescent lamp comprising a first envelop layer 104, an indium tin oxide layer (ITO) 106, a front bus bar 107, an electroluminescent layer 108, a dielectric layer 110, a rear electr layer layer 112, a first outer casing Second envelop layer 114. The far-away transfer paper 102 serves as a substrate for printing, and the other layers are sequentially printed on the 4-peel transfer paper 1 〇 2, so that the electroluminescent lamp can be produced as a separate product. However, when assembling the electroluminescent lamp to an electronic product, an adhesive layer 116 is first applied over the second outer shell layer 114, and the adhesive layer 116 is bonded to the electron together with the electroluminescent lamp. On the product, the peeling transfer paper 102 is then peeled off and peeled off, so that the electroluminescent lamp can be bonded to the electronic product tm, which is inconvenient to use. Further, since the electroluminescent lamp is entirely printed by ink, it is inferior in strength and is easily broken when subjected to external force. In addition, when the electroluminescent lamp is applied to a mobile phone (not shown), it is contacted with a button on the mobile phone through the outer surface of the first outer casing layer 1-4, and the first The outer shell layer 1〇4 is formed by printing with a layer of insulating ink, which is inferior in strength and is more susceptible to breakage when used in conjunction with the mobile phone length 6 1322636. The reason is that the inventors have felt that the above-mentioned deficiency can be improved, and proposes a present invention which is rational in design and effective in improving the above-mentioned deficiency. SUMMARY OF THE INVENTION An object of the present invention is to provide an electroluminescent lamp and a method of manufacturing the same that is not easily damaged and is easily attached to another electronic component. Another object of the present invention is to provide a combination of an electroluminescent lamp and a metal key plate, the combination of the electroluminescent lamp and the metal key plate being less susceptible to breakage and easy to be attached to a circuit board of a mobile phone. In order to achieve the above object, the present invention provides an electro-conductive bamboo shoot comprising: a substrate, an electro-sensitive printed on the substrate-side, an insulating protective layer covering the outer surface of the electroluminescent system, the insulating protective layer There are: a layer of glue and a piece of paper removed, the substrate is - a light-transmitting light system is provided in sequence from the base (four) 1 (four)

The adhesive rubber Lin (5, 8) can be pasted and used conveniently and quickly. ^ Invention towel ' If the conductive property of the light-transmitting conductive layer 21 is good, the V-electric circuit 22 can be omitted. The invention also provides a manufacturing method for manufacturing the above electroluminescent lamp, comprising the following steps: Step 1: preparing a light transmissive polyester film substrate i; 12 1322636 Step 2: laminating printing on the upper surface of the substrate 1 The electroluminescent system '&2> comprises the steps of: printing a laminated-transmissive conductive layer 21 on the substrate 1 with an indium tin oxide -1 ink; printing with a silver ink over the transparent conductive layer 21 Conductive line 22; printed on the conductive line 22 with a mixture of German and _ a light-emitting layer 23, the light-emitting layer 23 is provided with a second opening 29, and the second opening four is connected with the conductive line 22; The laminate-dielectric layer 24 is printed on the upper surface of the light-emitting layer 23 with a similar insulating ink such as barium titanate. The dielectric layer 24 is also provided with a second # port 29' on the side of the dielectric layer 24 with silver ink or The carbon ink printing layer is preferably an electrode layer 25'. The back electrode layer 25 is also provided with a first opening 29; Step 3: an insulating protective layer 3 is printed on the back electrode layer 25, and the insulating protective layer 3 is coated Electroluminescent system to the substrate (on the same as the electricity An outer layer of the light-emitting system, the insulating protective layer 3 is correspondingly provided with an opening 28 and a second opening 29; Step 4: applying a first layer of glue φ 4' above the insulating protective layer 3 An adhesive layer 4 is a layer of a rubber layer 4 coated on the insulating protective layer 3, and is also provided with a first opening 28 and a first opening 29; and step 5 : laying a layer of adhesive backing 5 which can be peeled off during use to prevent the first adhesive layer 4 from being polluted by the outside of the first adhesive layer 4, and manufacturing the above-mentioned electroluminescent lamp and metal The combination of the keypads includes the following steps in addition to the steps 1 to 4 of manufacturing the electroluminescent lamp described above: Step 5: Preparing a metal keypad 6 comprising - 13 1322636 lining 62 And a plurality of metal buttons 66, the lining 62 is provided with a plurality of accommodating grooves 64. The metal buttons 66 are correspondingly received in the accommodating grooves 64 of the lining. The second glue layer 7 , the pad 62 and the second adhesive layer 7 are also correspondingly provided with a first opening 28 And a younger one opening 2 9 '5 Xuanyuan a subbing layer 7 is also provided with a rubberized protective layer 8' to prevent the second adhesive layer 7 from being contaminated by the outside; Step 6: lining the metal key sheet 6 The inner side of the pad 62 is bonded to the first adhesive layer 4 of the electroluminescent lamp to form an electro-elective combination of the key plates. 'The above is only a preferred embodiment of the present invention. It is not intended to limit the scope of the patent protection of the present invention, and the equivalent changes of the present invention and the contents of the drawings are all included in the right of the present invention.
