ORGANIC LIGHT EMITTING DIODE AND ORGANIC LIGHT EMITTING DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240215288 titled 'ORGANIC LIGHT EMITTING DIODE AND ORGANIC LIGHT EMITTING DEVICE
The abstract describes an organic light emitting diode (OLED) with specific layers of red and blue emitting materials between two electrodes. The OLED achieves a balance of hole and electron injection to form an exciton recombination zone within the emitting material layer, resulting in controlled red and blue emission efficiencies.
- Red emitting material layer, first blue emitting material layer, and second blue emitting material layer are sequentially disposed between two electrodes.
- First blue host in the first blue emitting material layer has faster hole mobility than the second blue host in the second blue emitting material layer.
- Exciton recombination zone is formed within the emitting material layer due to balanced injection of holes and electrons.
- OLED achieves beneficial blue emission efficiency and high red emission lifetime.
- Organic light emitting device includes the OLED and can be used as a display device or a lighting device.
Potential Applications: - Display devices - Lighting devices
Problems Solved: - Achieving balanced red and blue emission efficiencies in OLEDs - Enhancing red emission lifetime
Benefits: - Improved blue emission efficiency - Extended red emission lifetime
Commercial Applications: Title: Advanced OLED Technology for Displays and Lighting This technology can be utilized in various commercial applications such as high-quality display screens for televisions, smartphones, and other electronic devices, as well as energy-efficient lighting solutions for homes and commercial buildings.
Questions about OLED Technology: 1. How does the OLED technology in this patent application differ from traditional LED technology?
- OLED technology uses organic materials that emit light when an electric current is applied, while traditional LED technology uses inorganic materials.
2. What are the key advantages of OLED technology over other lighting technologies?
- OLED technology offers flexibility, thinness, and energy efficiency compared to traditional lighting sources.
Original Abstract Submitted
an organic light emitting diode (oled) is described, where a red emitting material layer, a first blue emitting material layer and a second blue emitting material layer are disposed sequentially between two electrodes. a first blue host in the first blue emitting material layer has a hole mobility faster than a hole mobility of a second blue host in the second blue emitting material layer. holes and electrons are injected into an emitting material layer in balance so that an exciton recombination zone is formed within the emitting material layer. red and blue emission efficiencies are controlled in balance so that an oled with beneficial blue emission efficiency and high red emission lifetime can be realized. an organic light emitting device includes the organic light emitting diode, and can be a display device or a lighting device.
