Abstract
A system for displaying images includes an organic light-emitting device (OLED) including an anode layer on a substrate, a cathode layer, and an organic light-emitting layer disposed between the anode and cathode layers. The cathode layer includes a metal layer in direct contact with the organic light-emitting layer, a transparent conductive layer, and an organic buffer layer with a carrier mobility in a range of 10−3 cm2/(V·s) to 10−5 cm2/(V·s) disposed between the metal layer and the transparent conductive layer.

A system for displaying images, comprising:
- an organic light-emitting device comprising:
- an anode layer disposed on a substrate;
- an organic light-emitting layer disposed on the anode layer;
- and
- a cathode layer disposed on the organic light-emitting layer, comprising:
