Patent for License:

OLED With Rare-Earth Metal Containing Cathode    

A transparent rare-earth metal containing electron-injecting electrodes for use with OLED device


To enable the fabrication of OLED devices that contain transparent electron-injecting electrodes. The electrodes consist of a rare-earth metal or its alloy formed by co-evaporation with a conductive material. They could be used in transparent or surface emitting OLED.

High performance and transparent electrodes for bottom or surface emitted OLED

Primary Application of the Technology

The OLED could be used for the fabrication of transparent flat panel display.
