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, transferring excited state energy from the organic emissive material to non-radiative mode of 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, with the enhancement layer placed within a threshold distance from the organic emissive layer.
The claims of the patent detail the specific configurations and materials used in the device, including the requirement for a VDR value of 0.33 or greater in the organic emissive layer or material. The device may include a combination of materials within the organic emissive layer, forming an exciplex. Additionally, an outcoupling structure with nanoparticles may be present, coated with various materials such as metals, dielectrics, or hybrids. The patent also extends to consumer products incorporating the described device structure, emphasizing the importance of the specific characteristics and configurations outlined in the claims for optimal performance.
