The present invention discloses all-in-one organic electroluminescent inks for balanced charge injection. When of single layer organic lighting emitting diodes are made from these inks, the charge balance can be readily achieved. By using the invented all-in-one organic electroluminescent inks, both the device structure and the fabrication process are simplified, which will increase the production yield and reduce the production cost in manufacturing such devices. This invention also teaches methods to fabricate single layer all-in-one organic light emitting diodes. |
