LIGHT-EMITTING DEVICE AND ELECTRONIC APPARATUS INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17852154 titled 'LIGHT-EMITTING DEVICE AND ELECTRONIC APPARATUS INCLUDING THE SAME
Simplified Explanation
Abstract
A light-emitting device is described in this patent application. The device utilizes a dopant with a smaller absolute value of highest occupied molecular orbital (HOMO) energy level compared to another dopant. The difference between the HOMO energy level of the first dopant and the HOMO energy level of the host material is limited to 0.3 eV or less.
Patent/Innovation Explanation
- The patent application describes a light-emitting device.
- The device utilizes a dopant, which is a material added to modify the properties of the host material.
- The dopant with the smaller absolute value of HOMO energy level is selected among two dopants.
- The difference between the HOMO energy level of the selected dopant and the HOMO energy level of the host material is limited to 0.3 eV or less.
Potential Applications
- This technology can be used in the development of efficient and high-performance light-emitting diodes (LEDs).
- It may find applications in display technologies, such as OLED (organic light-emitting diode) displays.
- The light-emitting device can be used in various lighting applications, including general illumination and automotive lighting.
Problems Solved
- The technology addresses the challenge of achieving efficient light emission in devices by controlling the energy levels of the dopant and host materials.
- By limiting the difference in HOMO energy levels, the patent application aims to improve the performance and stability of the light-emitting device.
- The invention solves the problem of energy level mismatch between dopant and host materials, which can lead to reduced efficiency and undesirable side effects in light emission.
Benefits
- The light-emitting device described in the patent application offers improved efficiency and stability.
- By carefully selecting the dopant and controlling the energy levels, the device can achieve enhanced light emission properties.
- The technology has the potential to contribute to the development of more energy-efficient and longer-lasting lighting solutions.
