New description: [New technical field] This creation is about an improved structure of a light-emitting button, which is printed on one side of a transparent substrate, and printed with conductive plastic. The other side of the conductive plastic is printed with a light-emitting layer. The bottom surface of the luminescent layer is further formed with a dielectric layer, a backlight electrode layer and a protective layer. The conduction of the backlight electrode layer and the conductive plastic causes the electrons of the luminescent layer to change between the ground state and the excited state to release energy to emit light. Since the transparent substrate is printed with a conductive plastic, a thin transparent substrate can be used, and the thickness of the printed conductive plastic can be effectively reduced, so that the height of the button can be effectively reduced, and the conductive plastic material can be reduced. The cost reduction can also increase the splicability of the illuminating structure, making the buttons more flexible and convenient to use. [Prior Art] According to the data of the 3C products such as the conventional mobile phone and palm-sized computer (PDA), the key input is mainly used, and when used, it is often in a place where the light is not sufficient, and the light-emitting diode under the button is present. The light is transmitted by the button symbol, the luminosity is poor and uneven, the color of the light source is monotonous and the change is not easy, and the light-emitting diode system is adhered to the substrate. If the substrate needs to be replaced when the fault occurs, it is difficult to repair and assemble and improve. Cost; if it is often placed in a high degree of humidity, or when the phone is accidentally exposed to water during rainy days, water and moisture will penetrate into the inside of the phone through the small gap between the button and the outer casing of the mobile phone, which affects the missing operation of the circuit board in the mobile phone. Therefore, there is an improved structure of the light-emitting button as shown in the first and second figures. The surface of the button (1) is adhered to the elastic film (11), and the light-emitting element (2) is attached to the elastic film (11). The component (2) has a light-emitting layer (21) connected to a power source (22), a frequency converter (23), and opaque. M285790 and layer (12) are printed on the surface of the light-emitting layer (21) instead of The transparent layer (12) has a light-transmissive button symbol (121), and the light-emitting layer (21) comprises a polyester polymer transparent substrate (211) having a thickness of about 0.08 mm to 0.125 mm. An inorganic film (212') containing ITO metal is deposited by evaporation to a thickness of about i〇〇〇A°; on the other side of the inorganic film (212,), a light-emitting layer (213) is printed, and the light-emitting layer ( 213) A dielectric layer (214) is further formed on the bottom surface, and a backlight electrode layer (215) electrically connected to the light-emitting layer (213) is disposed at a bottom end of the dielectric layer (214). The surface of the light-emitting element (2) is printed with an opaque layer (12), and the opaque layer (12) has a light-transmitting button symbol (121), so that the power source (22) is turned on via the inverter ( 23) When the illuminating layer (21) is driven to emit light, the illuminating light can be transmitted from the button symbol (121). However, the surface of the transparent substrate (211) of the light-emitting layer (21) is first vapor-deposited with an inorganic film (212) such as an ITO metal film, and the transparent substrate (211) used for vapor deposition is thicker than the polyester material. And its π〇 metal film is also thick and ITO is wasting material, and the overall luminescent layer (21) is also thick and lacks elasticity and winding property. It must be processed by special evaporation, which causes inconvenience of button manufacturing and processing. . Lu can thus see that there are still many shortcomings in the above-mentioned items, which is not a good designer, but needs to be improved. In view of the shortcomings derived from the improved structure of the above-mentioned conventional luminous buttons, the creators of this case have improved and innovated, and after years of painstaking research, they finally succeeded in researching and developing the improved structure of the luminous button of this piece. [New content] The purpose of this creation is to provide an improved structure for a light-emitting button, which has a light-emitting 7L member (2) of a button (1) and a thin transparent substrate (211) having a thickness of about 6
