It relates to an electromagnetic wave shielding structure for shielding electromagnetic waves from EL products.

EL (Electro Luminescent) emits light by electrical stimulation of a fluorescent crystal evenly distributed between two electrodes with excellent conductivity. When an AC voltage is applied, the electric field causes the phosphor to quickly charge and discharge. The phenomenon in which the movement of electrons appears as light in this cycle is called EL.

In general, EL is operated by AC no matter how small power is used for its operation principle. In order for EL to emit light, AC power must be supplied and the voltage must be at least 90V to operate normally.
