Light-Emitting Element, Display Module, Lighting Module, Light-Emitting Device, Display Device, Electronic Appliance, and Lighting Device - A simplified explanation of the abstract
This abstract first appeared for US patent application 18509704 titled 'Light-Emitting Element, Display Module, Lighting Module, Light-Emitting Device, Display Device, Electronic Appliance, and Lighting Device
Simplified Explanation
The multicolor light-emitting element described in the patent application utilizes fluorescence and phosphorescence, making it advantageous for practical applications. The element consists of a stacked-layer structure with a first light-emitting layer containing a host material and a fluorescent substance, and a second light-emitting layer containing two organic compounds and a substance that can convert triplet excitation energy into luminescence. The light emitted from the first layer has a shorter wavelength than the light emitted from the second layer.
- The light-emitting element utilizes both fluorescence and phosphorescence.
- It has a stacked-layer structure with distinct light-emitting layers.
- The first layer contains a host material and a fluorescent substance.
- The second layer contains two organic compounds and a substance for converting triplet excitation energy into luminescence.
- Light emitted from the first layer has a shorter wavelength than light emitted from the second layer.
Potential Applications

Original Abstract Submitted
A multicolor light-emitting element that utilizes fluorescence and phosphorescence and is advantageous for practical application is provided. The light-emitting element has a stacked-layer structure of a first light-emitting layer containing a host material and a fluorescent substance and a second light-emitting layer containing two kinds of organic compounds and a substance that can convert triplet excitation energy into luminescence. Note that light emitted from the first light-emitting layer has an emission peak on the shorter wavelength side than light emitted from the second light-emitting layer.
