Abstract

A method for manufacturing a directly printable electrochemiluminescent device involves printing ECL (Electrochemiluminescence) ink onto a pair of graphene-on-silver printed electrodes using 3D printing technology to create an electrochemiluminescent device at a desired location and shape. The present invention enables uniform light emission in the light-emitting region and, by using directly printable ECL Ink to locally print only the light-emitting part, has the effect of freely realizing the light-emitting element in a desired shape.
