ORGANIC LIGHT-EMITTING DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18400296 titled 'ORGANIC LIGHT-EMITTING DEVICE
Simplified Explanation
The organic light-emitting device described in the patent application includes multiple sub-emission layers that emit light of different wavelengths, with each sub-emission layer containing a different color light-emitting dopant. The device also features a hole control layer, an electron control layer, and an exciplex formed by the host materials in the sub-emission layers.
- Explanation of the patent/innovation:
- Organic light-emitting device with multiple sub-emission layers emitting light of different wavelengths - Each sub-emission layer contains a different color light-emitting dopant - Hole control layer and electron control layer included in the device - Exciplex formed by the host materials in the sub-emission layers
- Potential applications of this technology:
- High-resolution displays - Lighting applications - Flexible and transparent displays
- Problems solved by this technology:
- Improved color accuracy and brightness in displays - Enhanced energy efficiency - Reduced manufacturing costs
- Benefits of this technology:
- Enhanced visual experience for users - Energy-efficient lighting solutions - Cost-effective manufacturing processes
- Potential commercial applications of this technology:
- Consumer electronics - Automotive displays - Wearable technology
- Possible prior art:
- Previous organic light-emitting devices with single emission layers - Exciplex-based OLED technologies
Questions:
1. How does the exciplex formed by the host materials in the sub-emission layers contribute to the overall performance of the organic light-emitting device? 2. What specific advantages does the inclusion of multiple sub-emission layers with different color light-emitting dopants offer compared to traditional OLED technologies?
Original Abstract Submitted
An organic light-emitting device and display apparatus, the device including a first electrode; a second electrode facing the first electrode; an emission layer between the first and second electrode; a hole control layer between the first electrode and the emission layer; and an electron control layer between the emission layer and the second electrode, wherein the emission layer includes a plurality of sub-emission layers to emit light having different wavelengths, at least portions of the plurality of sub-emission layers do not overlap one another, the plurality of sub-emission layers include: a first sub-emission layer including a first color light-emitting dopant, and a second sub-emission layer including a second color light-emitting dopant, the first and second sub-emission layers each include a hole-transporting and electron-transporting host which form an exciplex, and a triplet energy of the exciplex is equal to or greater than triplet energies of the first and second color light-emitting dopant.
