ORGANIC LIGHT-EMITTING DEVICE AND ELECTRONIC APPARATUS INCLUDING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240324267 titled 'ORGANIC LIGHT-EMITTING DEVICE AND ELECTRONIC APPARATUS INCLUDING THE SAME

The abstract describes a light-emitting device with an emission layer containing a first host, a second host, a first dopant, and a second dopant. The first dopant is a metal-containing compound, the second dopant is a boron-containing compound, and the hosts form a host exciplex in a triplet state, which is also in a local-excitation state.

• The light-emitting device includes a unique combination of hosts and dopants to achieve specific emission properties.
• The first dopant is a metal-containing compound, while the second dopant is a boron-containing compound, contributing to the device's performance.
• The hosts form a host exciplex in a triplet state, which enhances the device's efficiency and emission characteristics.
• The host exciplex in the triplet state is also in a local-excitation state, further optimizing the device's light-emitting capabilities.
• This innovation in light-emitting devices offers potential advancements in display technology and lighting applications.
