Abstract
An electric controlled color change electro luminescent element is disclosed. An EL element is connected to a driving system by a first pin and a second pin. The driving system has a function of changing driving voltage. The driving system is switched through a switch for changing the way for supplying voltage or switching to different driving IC to change the output bias or current frequency. Thereby, the color and brightness of the EL element are changed.
Claims6
An electric controlled color change electro luminescent element having an EL element, the EL element being formed by overlapping a front side electrode, a light emitting layer, an electron-inducing layer, and a backside electrode;
