Application: Organic electroluminescent devices (Patent ID: US20240215302A1)

The patent filed by Universal Display Corp. describes compounds, formulations, and devices utilizing compounds for devices with a substrate, first electrode, and an organic emissive layer containing an organic emissive material. An enhancement layer with a plasmonic material exhibiting surface plasmon resonance is included, which non-radiatively couples to the organic emissive material and transfers excited state energy to surface plasmon polaritons. The organic emissive material must have specific decay rate constants and a vertical dipole ratio (VDR) value of 0.33 or greater. Additionally, at least one component of the device must be corrugated.

The claims of the patent detail the specific requirements for the device, including the VDR value of the organic emissive layer, the composition of the organic emissive material, and the structure of the organic emissive layer. The device can utilize phosphorescent, fluorescent, or Thermally Activated Delayed Fluorescence (TADF) materials, and emission can originate from a combination of materials within the organic emissive layer. The patent also covers the use of nanoparticles in an outcoupling structure, with various options for the composition and coating of the nanoparticles. Furthermore, the patent extends to consumer products incorporating the described device structure, emphasizing the importance of the specific distance between the enhancement layer and the organic emissive layer, as well as the decay rate constants and VDR value of the organic emissive material.
