==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 ==
The technology can be used in:
* Display panels
* Lighting fixtures
* Signage
* Decorative lighting

== Problems Solved ==
* Limited color options in traditional light-emitting elements
* Inefficient energy conversion in some light-emitting devices

== Benefits ==
* Enhanced color options
* Improved energy efficiency
* Longer lifespan of the light-emitting element

== Potential Commercial Applications ==
"Multicolor Light-Emitting Element: Commercial Applications"

== Possible Prior Art ==
No prior art is known at this time.

==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.
