Abstract

The present invention provides a kind of dual-face light-emitting type electroluminescent plate apparatus and its manufacturing method. The invention is featured with using transparent electrode material on the electrodes on both front and back faces, in which a light-emitting layer is coated on both front and back faces, respectively. In addition, the dielectric layer between both light-emitting layers is used commonly, so as to have excellent characteristics of simple structure and convenient application. Thus, it is capable of saving material and labor cost. The manufacturing method is described in the following. On the transparent conductive substrate, the first light-emitting layer, the dielectric layer, the second light-emitting layer, and the second transparent conductive layer are coated. Then, coating of passivation/insulation layer, or the protection-cover manner is used to protect the light plate, so as to finish the manufacture. Additionally, the manufacturing method can be the followings: coating the first light-emitting layer and the dielectric layer to manufacture the first single-face semi-product; following the same procedure and the manner to complete the second single-face semi-product; using a suitable bonding manner to bond back sides of both single-face electroluminescent plates of both single-face semi-products together; and using protection-cover or the other manner to protect the light plate so as to finish the manufacture. For the other manufacturing method, the first light-emitting layer and the dielectric layer are sequentially coated on the transparent substrate to manufacture the first single-face semi-product. The same procedure and manner are used to manufacture the second single-face semi-product, which is coated to the second light-emitting layer only on the transparent conductive substrate. After that, a suitable bonding manner is used to bond together backsides of both single-face electroluminescent plates for both single-face semi-products. Then, the protection-cover or the other manner is used to protect the light plate so as to finish the fabrication.
