EL( electroluminescence)
EL冷光片结构图Electroluminescence means luminescence produced by high energy generated from electrons which are accelerated within phosphors when an alternating current is applied to a luminous layer consisting of phosphor powder。
EL element is largely divided into two types; dispersion-type EL with luminous layer consisting of phosphors and thin film-type EL consisting of dense thin films。 Each EL is also subdivided into alternating current type and direct current type according to driving method。
