==LIGHT-EMITTING DEVICE, ELECTRONIC APPARATUS INCLUDING THE LIGHT-EMITTING DEVICE, AND ELECTRONIC DEVICE INCLUDING THE LIGHT-EMITTING DEVICE - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18339045 titled 'LIGHT-EMITTING DEVICE, ELECTRONIC APPARATUS INCLUDING THE LIGHT-EMITTING DEVICE, AND ELECTRONIC DEVICE INCLUDING THE LIGHT-EMITTING DEVICE

==Simplified Explanation==

The abstract describes a light-emitting device that includes electrodes, an interlayer with an emission layer, and a capping layer. The emission layer contains an emitter that emits light in a specific wavelength range, and the capping layer is designed to allow the emitted light to pass through. The device utilizes iridium for the emitter and an amine-containing compound for the capping layer. The abstract also mentions a calculated value called the RRF value, which is determined using Equation 1.

* The light-emitting device includes electrodes, an interlayer, and a capping layer.
* The emission layer within the interlayer contains an emitter that emits light in the range of 610 nm to 720 nm.
* The emitter in the emission layer is made of iridium.
* The capping layer, which is in the path of the emitted light, contains an amine-containing compound.
* The RRF value, calculated using Equation 1, is used to determine the efficiency of light extraction through the capping layer.

Potential Applications:
* Lighting systems: The light-emitting device can be used in various lighting applications, such as residential, commercial, or automotive lighting.
* Display technology: The device can be integrated into displays, such as OLED screens, to enhance color accuracy and brightness.

Problems Solved:
* Efficient light extraction: The design of the capping layer allows for improved light extraction, ensuring maximum brightness and efficiency of the device.
* Wavelength control: The specific wavelength range of the emitted light allows for precise color reproduction in lighting and display applications.

Benefits:
* Enhanced color accuracy: The use of iridium as the emitter and the specific wavelength range of the emitted light contribute to improved color accuracy in lighting and display technologies.
* Improved efficiency: The optimized design of the capping layer and the calculated RRF value ensure efficient light extraction, maximizing the overall efficiency of the device.
