    • An EL sheet using a multi-layer thin sheet and a metal dome sheet using the same are provided. An ITO layer is formed on a primary film, and a base film is fused to the primary film at a bottom thereof to form a multi-layer transparent conductive layer. On the latter, an EL layer is formed in sequence with a bus-bar, fluorescent layer, dielectric layer, bottom electrode layer, and metal lead line. Such an EL has a protective layer covering it that absorbs external shocks and pressure. By using the thin film, the thickness of the keypad can be minimized, and the button feel is more precise with an improved feel. When inks of different characteristics are repetitively printed and heat treated, curling can be prevented by using two layers, and an ESD shield layer prevents damage from static electricity.
    • 提供了使用多层薄片的EL片和使用其的金属圆顶片。 在初级膜上形成ITO层,底层与底膜熔融,形成多层透明导电层。 在后者中,依次形成有母线,荧光层,电介质层,底部电极层和金属引线的EL层。 这种EL具有覆盖其的保护层,其吸收外部冲击和压力。 通过使用薄膜,可以使键盘的厚度最小化,并且按钮感觉更精确并且具有改善的感觉。 当不同特性的油墨被重复印刷和热处理时,可以通过使用两层来防止卷曲,并且ESD屏蔽层防止静电损坏。
