EL 是Electroluminescence簡(jiǎn)寫。

意思是 電致發(fā)光。 下面是英語(yǔ)翻譯，你自己看看吧。 Electroluminescence (EL) is an optical phenomenon and electrical phenomenon in which a material emits light in response to an electric current passed through it, or to a strong electric field. This is distinct from light emission resulting from heat (incandescence), chemical reaction (chemiluminescence), sound (sonoluminescence), or other mechanical action (mechanoluminescence).ortswe
