A FLEXIBLE AC POWER EL STRUCTURE OF POWDER TYPE HAVING A EXTENDED LIGHTENING AREA AND GOOD RESISTANCE TO MOISTURE, A METHOD OF MANUFACTURING THE SAME, A FLUORESCENT MATERIAL USED IN THE MANUFACTURE AND A METHOD OF PREPARATION OF THE FLUORESCENT MATERIAL

摘要

The present invention relates to a flexible EL lamp that can extend emission region. In the flexible EL lamp, a phosphor layer, a dielectric layer, and a front electrode layer are exposed to the outside by extending to edge portion of the product. The phosphor layer that is vulnerable to moisture is formed of the phosphor material to which water repellent process is performed. Therefore, the reliability characteristic with respect to moisture can be obtained. The EL lamp can facilitate the design of the compact mobile phones and can improve the reliability of the product.
