LIGHT-EMITTING DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18383842 titled 'LIGHT-EMITTING DEVICE
Simplified Explanation
The patent application describes a light-emitting device with multiple subpixels emitting different colors of light.
- The device includes first electrodes in three subpixels, a second electrode facing the first electrodes, and emission layers for emitting different colors of light.
- A layer is integrated with the subpixels and serves as a barrier between the electrodes and emission layers.
- A hole transport region is included between the electrodes and the layers to facilitate the movement of charge carriers.
- Additional layers such as an auxiliary layer and an intermediate layer are included to enhance the performance of the device.
- Potential Applications:**
- Display technology for electronic devices
- Lighting applications for signage or decorative purposes
- Automotive lighting for interior or exterior use
- Problems Solved:**
- Efficient emission of multiple colors of light in a single device
- Improved integration of layers for better performance
- Enhanced charge carrier transport for more reliable operation
- Benefits:**
- Higher quality and more vibrant color display
- Energy-efficient operation
- Longer lifespan compared to traditional light-emitting devices
Original Abstract Submitted
A light-emitting device includes: a plurality of first electrodes respectively disposed in a first subpixel, a second subpixel, and a third subpixel; a second electrode facing the plurality of first electrodes; a first emission layer disposed in the first subpixel to emit a first-color light; a second emission layer disposed in the second subpixel to emit a second-color light; a first layer disposed between the second electrode and each of the first emission layer and the second emission layer, and integrated with the first subpixel, the second subpixel, and the third subpixel; a hole transport region disposed between the plurality of first electrodes and each of the first layer, the first emission layer, and the second emission layer; a first auxiliary layer disposed between the hole transport region and the first emission layer; and a first intermediate layer disposed between the first auxiliary layer and the first emission layer.
