LIGHT-EMITTING DEVICE AND ELECTRONIC APPARATUS INCLUDING SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17690268 titled 'LIGHT-EMITTING DEVICE AND ELECTRONIC APPARATUS INCLUDING SAME
Simplified Explanation
The patent application describes a light-emitting device and an electronic apparatus that includes the device. The device consists of an emission layer sandwiched between two electrodes. The emission layer is composed of two sub-layers, with the first sub-layer in direct contact with the second sub-layer. The first sub-layer contains a dopant, a hole-transporting compound, and an electron-transporting compound, while the second sub-layer contains a different dopant, hole-transporting compound, and electron-transporting compound. The electron mobility of the second electron-transporting compound is greater than that of the first electron-transporting compound.
- The light-emitting device includes an emission layer with two sub-layers.
- The first sub-layer is in direct contact with the second sub-layer.
- The first sub-layer contains a dopant, a hole-transporting compound, and an electron-transporting compound.
- The second sub-layer contains a different dopant, hole-transporting compound, and electron-transporting compound.
- The electron mobility of the second electron-transporting compound is higher than that of the first electron-transporting compound.
Potential Applications
- Display technology, such as OLED screens.
- Lighting technology, such as OLED-based lighting panels.
- Electronic devices, such as smartphones, tablets, and televisions.
Problems Solved
- Improved efficiency and performance of light-emitting devices.
- Enhanced electron mobility in the emission layer.
- Better control over the emission of light.
Benefits
- Higher electron mobility leads to improved device performance.
- Increased efficiency and brightness of light emission.
- Greater control over the color and intensity of emitted light.
