US Patent 8723164: Electronic Device

• Title: Electronic device
• Current Assignee: Pictiva Displays International Ltd
• Inventors: Guenter Schmid, Ralf Krause, Stefan Seidel, Oliver Weiss, Christoph Gaerditz, Riikka Suhonen, Ulrich Niedermeier, Fryderyk Kozlowski

• Abstract: An electronic device is described, which includes a substrate, a first electrode, at least one organic functional layer, and a second electrode. The organic functional layer is positioned between the two electrodes and contains at least a first, a second, and a third matrix material. A key feature is that the first matrix material has a larger band gap compared to both the second and third matrix materials.

Plain-Language Overview of Independent Claims:

• Claim 1: This claim describes an electronic device comprising a substrate, a first electrode, at least one organic functional layer, and a second electrode. The organic functional layer is located between the electrodes and contains three matrix materials (first, second, and third). The third matrix material has a Lowest Unoccupied Molecular Orbital (LUMO) that is energetically lower than the LUMOs of the first and second matrix materials. The second matrix material has a Highest Occupied Molecular Orbital (HOMO) that is energetically higher than the HOMOs of the first and third matrix materials. Crucially, this organic functional layer is specifically an emission layer that is doped with at least one emitter material.

• Claim 15: This claim also describes an electronic device with the same basic structure and matrix material energy level relationships as Claim 1. However, it adds a specific characteristic for the first matrix material: its LUMO is energetically higher than the LUMOs of both the second and third matrix materials, and its HOMO is energetically lower than the HOMOs of both the second and third matrix materials.

• Claim 16: Similar to Claim 15, this claim also describes an electronic device with the same fundamental structure and matrix material energy level relationships as Claim 1. The distinguishing feature here is that the first matrix material has a charge carrier mobility that is lower than the charge carrier mobilities of both the second and third matrix materials.
