Description

Advertising board and production method using an electroluminescent body

The present invention relates to a billboard manufacturing method using an electroluminescent body, and more specifically, to a billboard divided by using an electroluminescent body to have an advertising effect such as neon sign by varying the supply and color of power for each divided area by dividing the bottom metal plate. It is about a manufacturing method.

In general, an electroluminescent material (hereinafter referred to as EL) is an electrode attached to both sides of a plate-shaped light emitting layer, and when a strong electric field is applied to the electrode, an electric field acts to emit light and the light emitting material emits light. It is called EL.

The light emitting layer is a solidified light emitting material such as zinc sulfide (ZnS) in powder form. There are plastic type and ceramic type. Copper, chlorine, manganese, etc. are added as an active agent. Manganese-doped zinc sulfide, which is commonly used, is very sensitive to moisture and is used by applying a protective film made of a thin film insulating material.

Referring to the configuration of the EL display element as shown in Fig. 1, the phosphor 11 hardened by compounding a plurality of light emitting materials in powder form and molding into a plate shape has good conductivity on the upper end of the phosphor 11; A conductive layer 12 formed by incorporating ITO (Indium Tin Oxide) metallicity, and a transparent glass substrate 13 and a lower end of the phosphor 11 so that a light emitting material can be seen on the upper end of the conductive layer 12. A metal electrode plate 14 made of aluminum or silver with good conductivity, and a lower glass substrate 15 that protects the metal plate at the lower end of the metal electrode plate 14 and has a moisture proof function.

One electrode may be an opaque metal in the electrodes deposited on both sides of the light emitting layer, but the other electrode uses a transparent electrode to display light to the outside. That is, it is deposited by mixing indium tin oxide (ITO) metallicity, and transparently coated so that the light emitting material can be seen at the top.

The operating principle of the EL display element is that the anode is placed on the conductive layer 12, which is the upper metal wave of the phosphor, and the cathode is placed on the metal electrode plate 15 on the bottom, and a strong electric field of alternating voltage and direct current is applied. It moves to the anode of the conductive layer 12 which is a metal plate. The free electrons are moved by the electric field, and the accelerated free electrons excite electrons of a specific impurity (activator) which becomes the emission center in the light emitting material. The excited electrons try to maintain a stable state. When the excited electrons return to their original form, they release energy and represent it as light.

However, the EL display element is made of an EL lamp and has been put into practical use as a display device. However, the EL display element has been difficult to be used for an advertisement device such as neon sign by the prior art.

In addition, the conventional fluorescent neon signs are fragile, weak in pressure and shock, there is a lot of risk of short circuit and electric shock, there was a problem in use in a narrow space inconvenient.

Therefore, an object of the present invention was devised to solve the above problems, the surface of the lower metal plate by dividing the lower portion of the divided area of the power supply and color by using an electroluminescent board to have the effect of advertising such as neon sign. To provide a way to build.
