Abstract

The utility model relates to an improved luminous key structure, one side of transparent base material is printed with an organic conductive film and the other side of the conductive film is printed with a luminescent layer again. The bottom surface of the luminescent layer forms a dielectric layer again, the bottom end of the dielectric layer is provided with a back light electrode layer which is electrically connected with the luminescent layer, the lower margin of a back electrode layer forms a protective layer and the electric conduction of the backlight electrode layer and the organic conductive film causes electron of the luminescent layer to transform between ground state and excited state to release energy to emit light. Because the transparent base material is printed with the organic conductive film, the transparent base material with thin thickness is used and the thickness of the printed organic conductive film can also be reduced effectively. Thus, except the height of the key can be reduced effectively and the materials input of the organic conductive film is reduced to reduce the cost. The reelability of a luminescent structure is also increased, causing the key to have elasticity to have convenient use.

Description

Improved luminous button structure

Technical field

The utility model relates to a kind of luminous button structure, relates in particular to a kind of improved luminous button structure.

Background technology

The data input of the mobile phone of commonly using, palmtop computer 3C Products such as (PDA) is mainly imported with button, and often be in light and insufficient place when using, and the luminous of light-emitting diode under button arranged, again by key symbols place printing opacity, its luminosity difference and inhomogeneous, light source colour is dull and change to be difficult for, and light-emitting diode is to stick on substrate, need change substrate during as if fault, and real not easy-maintaining and assembling also raise the cost; If often place the wetness height, or mobile phone is met water because of carelessness during rainy day, and water and aqueous vapor all can be via the trickle space infiltration mobile phone inside of button and phone housing, is disappearance such as system and influence that circuit board in the mobile phone operates.So just like Fig. 1, the utility model of improved luminous button structure shown in 2, the surface of this button 1 is to paste elastic film 11, on elastic film 11, post luminescence component 2 again, this luminescence component 2 tools one luminescent layer 21, and be connected in a power supply 22, frequency converter 23, and light non-transmittable layers 12 is arranged in luminescent layer 21 surface printings, and on the light non-transmittable layers 12 and have a key symbols 121 of light-permeable, and the transparent base 211 ' that contains polyester macromolecule of its luminescent layer 21, the about 0.08mm of its thickness～0.125mm surface evaporation has one deck to contain the inorganic thin film 212 ' of ITO metal, the about 1000A of its thickness.The dust person; This inorganic thin film 212 ' another side then republishes luminescent layer 213, and these luminescent layer 213 bottom surfaces then form a dielectric layer 214 again, in the bottom of dielectric layer 214 is to have the electrode layer backlight 215 that can electrically connect with luminescent layer 213.Mat has light non-transmittable layers 12 in luminescence component 2 surface printings, and on the light non-transmittable layers 12 and have the key symbols 121 of light-permeable, so power-on 22 is luminous through frequency converter 23 driven for emitting lights layers 21, then luminous light can be from key symbols 121 place's printing opacities.Transparent base 211 surfaces of this luminescent layer 21 are that first evaporation has one deck inorganic thin film 212 ' as the ITO metallic film, not only the employed transparent base 211 of evaporation is that polyester material is thicker, and the also thicker and ITO waste material of its ITO metallic film, whole again luminescent layer 21 is also thicker and lack flexibility and coiling property, must cause the inconvenience of button manufacturing processing earlier through the processing of special evaporation again.

This shows that the above-mentioned article of commonly using still have many disappearances, real non-one kindhearted design, and demand urgently being improved.

This case creator commonly uses every shortcoming that improved luminous button structure is derived in view of above-mentioned, is urgently to think to be improved innovation, and after concentrating on studies through taking great pains to attain one's goal for many years, successfully the improved luminous button structure of this part is finished in research and development finally.

Summary of the invention

It is a kind of in improved luminous button structure that the purpose of this utility model promptly is to provide, the thin transparent base of knowing 211 of luminescence component 2 tools of its button 1, about 0.02mm～the 0.03mm of its thickness, it simultaneously prints one deck electroconductive organic film 212, and these conduction electroconductive organic film 212 another sides then republish the luminous button of luminescent layer 213.But and the thin transparent base of used thickness, and the thickness of the electroconductive organic film of printing also can effectively reduce, therefore remove the height that can effectively reduce button, and the materials that can reduce electroconductive organic film are to reduce cost, also can increase the reelability of its ray structure, make button have more elasticity and convenient the use.

It is a kind of in improved luminous button structure that another purpose of the present utility model promptly is to provide, and it is that one side in luminescence component 2 directly is printed with electroconductive organic film 212, must can effectively not simplify button and make procedure earlier through the processing of special evaporation.

Can reach the improved luminous button structure of above-mentioned novel purpose; it is simultaneously to be printed with electroconductive organic film in transparent base; this electroconductive organic film another side then republishes luminescent layer; this luminescent layer bottom surface then forms a dielectric layer again; the bottom of dielectric layer is to have the electrode layer backlight that can electrically connect with luminescent layer; the lower edge of its dorsum electrode layer then forms a protective layer; the electronics that makes luminescent layer by the conduction of electrode layer backlight conversion and releasing energy with luminous between ground state and excite state makes button or key symbols be able to printing opacity.

Improved luminous button structure provided by the utility model is commonly used article mutually relatively the time with other, has more following advantage:

1. the utility model is to be the printing electroconductive organic film on transparent base, but and the thin transparent base of used thickness, and the thickness of the electroconductive organic film of printing also can effectively reduce, therefore remove the height that can effectively reduce button, and the materials that can reduce electroconductive organic film are to reduce cost, also can increase the reelability of its ray structure, make button have more elasticity and convenient the use.

2. the utility model is to be printing one deck electroconductive organic film in transparent base, and it is for containing the organic polymer conductive film of PEDOT, and must can not simplify button and make procedure earlier through the processing of special evaporation.
