LIGHT-EMITTING DEVICE AND APPARATUS INCLUDING SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18444740 titled 'LIGHT-EMITTING DEVICE AND APPARATUS INCLUDING SAME
The patent application describes a light-emitting device with a unique organic layer structure that includes both emission units and charge generating units.
- The organic layer consists of m emission units and (m-1) charge generating units, where m is a natural number of 2 or greater.
- At least one of the charge generating units includes an n-type charge generating layer, a p-type charge generating layer, and a p-type hole injection layer.
- The n-type charge generating layer contains an n-type organic compound and a metal material, while the p-type charge generating layer and p-type hole injection layer each include an inorganic semiconductor material.
Potential Applications: - This technology can be used in the development of high-performance light-emitting devices for various applications such as displays, lighting, and signage.
Problems Solved: - The technology addresses the need for efficient and stable organic light-emitting devices by optimizing the organic layer structure.
Benefits: - Improved efficiency and stability of light-emitting devices. - Enhanced performance in terms of brightness and color accuracy.
Commercial Applications: - The technology can be applied in the manufacturing of OLED displays, lighting panels, and other electronic devices requiring high-quality light emission.
Questions about the technology: 1. How does the inclusion of both emission units and charge generating units in the organic layer improve the performance of the light-emitting device? 2. What advantages does the use of inorganic semiconductor materials in the charge generating layers provide compared to organic materials?
Original Abstract Submitted
A light-emitting device and an apparatus including the same include a first electrode, a second electrode facing the first electrode; and an organic layer between the first electrode and the second electrode, wherein the organic layer includes m emission units and (m−1) charge generating units, each of the charge generating units being between the emission units that are adjacent to each other, m is a natural number of 2 or greater, at least one of the (m−1) charge generating units includes an n-type charge generating layer, a p-type charge generating layer, and a p-type hole injection layer, wherein the n-type charge generating layer includes an n-type organic compound and a metal material, and wherein the p-type charge generating layer and the p-type hole injection layer each independently include an inorganic semiconductor material.
