ORGANIC LIGHT EMITTING ELEMENT - A simplified explanation of the abstract
This abstract first appeared for US patent application 18583626 titled 'ORGANIC LIGHT EMITTING ELEMENT
The patent application describes an organic light emitting element with specific relationships between the HOMO and LUMO levels of the host material and the light emitting dopant material in the light emission layer.
- The element includes an anode, a cathode, a first organic compound layer, a light emission layer with a host material and a light emitting dopant material, and a second organic compound layer.
- The materials for the layers are selected so that the hole mobility of the first organic compound layer is equal to or greater than the electron mobility of the second organic compound layer.
Potential Applications: - Display technology - Lighting applications - Electronic devices
Problems Solved: - Enhanced efficiency in light emission - Improved performance in organic light emitting elements
Benefits: - Higher efficiency in light emission - Better overall performance in organic light emitting devices
Commercial Applications: Organic light emitting displays, lighting products, and electronic devices could benefit from this technology, leading to improved energy efficiency and performance.
Questions about the technology: 1. How does the specific relationship between HOMO and LUMO levels impact the performance of the organic light emitting element? 2. What are the potential implications of equalizing hole mobility and electron mobility in the organic compound layers?
Original Abstract Submitted
An organic light emitting element that includes an anode, a cathode, a first organic compound layer, a light emission layer containing a host material and a light emitting dopant material, and a second organic compound layer. The relationships concerning HOMO levels and LUMO levels of the host material and the light emitting dopant material in the light emission layer are specified, and the materials for these layers are selected so that the hole mobility of the first organic compound layer is equal to or greater than the electron mobility of the second organic compound layer.
