    • A flexible EL device comprises a substrate, which is made of highly polymerized synthetic rubber, polyurethane, or silicon rubber, a conductive layer, a dielectric layer, a fluorescent layer, a transparent conductive layer, and a polymer protection film layer. Due to the high flexibility of the substrate, the flexibility of the flexible EL device according to the present invention is higher than the conventional EL device using PET, and therefore, the durability of the flexible EL device under mechanical impact is improved. As a result, the flexible EL device is not damaged when physical impacts are applied to the flexible EL device. Furthermore, noise is prevented or reduced by simply changing the structure of the flexible EL device and adding material layers, and therefore, electric and physical properties of the flexible EL device are improved. The flexible EL device is applicable to EL dome sheets or EL keypads.
    • 柔性EL器件包括由高分子合成橡胶,聚氨酯或硅橡胶,导电层,电介质层,荧光层,透明导电层和聚合物保护膜层制成的基片。 由于基板的高灵活性,根据本发明的柔性EL器件的柔性高于使用PET的常规EL器件,因此柔性EL器件在机械冲击下的耐久性得到改善。 结果,当对柔性EL器件施加物理冲击时,柔性EL器件不会损坏。 此外,通过简单地改变柔性EL器件的结构和添加材料层来防止或减少噪声,因此柔性EL器件的电学和物理特性得到改善。 柔性EL器件适用于EL圆顶片或EL键盘。
