ABSTRACT:
A cathode structure for inverted OLEDs is provided, which comprise a substrate, a conductive electrode layer, an organic material layer, a dielectric layer, and a metal layer. Wherein, the conductive electrode layer is disposed over the substrate, the organic structure layer is disposed over the conductive electrode layer, the dielectric layer is disposed over the organic material layer, and the metal layer is disposed over the dielectric layer. Such cathode structure can function without using the metals of low work function and high chemical activity so as to benefit the manufacturing of organic light emitting devices and displays, and provide a more stable working conditions.
