摘要： There is provided a driving circuit for an EL element which extends the life of the EL element and has improved driving efficiency.
A capacitor 11 is parallel-connected to a series circuit 3 formed by an EL element 1 and an inductor 2 to cause harmonic components and a driving frequency lower than the same to pass through the capacitor 11 and the EL element 1, respectively, to extend the life of the EL element and to improve driving efficiency.摘要翻译： 提供了EL元件的驱动电路，其延长了EL元件的使用寿命并提高了驱动效率。 电容器11并联连接到由EL元件1和电感器2形成的串联电路3，以分别使谐波分量和低于其的驱动频率通过电容器11和EL元件1延伸 EL元件的使用寿命和提高驱动效率。
