ORGANIC LIGHT-EMITTING DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18157335 titled 'ORGANIC LIGHT-EMITTING DEVICE
Simplified Explanation
An organic light-emitting device (OLED) is described in this patent application. The device consists of a first electrode, a second electrode, and an organic layer in between. The organic layer contains an emission layer, which is composed of a first compound, a second compound, and a third compound.
- The first compound is a hole transporting host compound.
- The second compound is an electron transporting host compound.
- The third compound can be either a hole transporting host compound or an electron transporting host compound.
The first compound and the second compound combine to form a first exciplex, while the first compound and the third compound (or the second compound and the third compound) form a second exciplex. Importantly, the first exciplex and the second exciplex are distinct from each other.
Potential applications of this technology:
- OLED displays for electronic devices such as smartphones, tablets, and televisions.
- Lighting applications, including OLED-based lamps and fixtures.
- Flexible and wearable displays due to the organic nature of the device.
Problems solved by this technology:
- Enhanced efficiency and performance of OLED devices.
- Improved color reproduction and brightness.
- Reduction in power consumption and longer device lifespan.
Benefits of this technology:
- Higher efficiency and brightness compared to traditional OLED devices.
- Greater flexibility and versatility in design and form factor.
- Potential for lower production costs due to the use of organic materials.
Original Abstract Submitted
An organic light-emitting device includes: a first electrode; a second electrode; and an organic layer between the first electrode and the second electrode, wherein the organic layer includes an emission layer having a first layer, and the first layer includes a first compound, a second compound, and a third compound. The first compound is a hole transporting host compound, the second compound is an electron transporting host compound, and the third compound is a hole transporting host compound or an electron transporting host compound. The first compound and the second compound form a first exciplex, and the first compound and the third compound, or the second compound and the third compound form a second exciplex, where the first exciplex and the second exciplex are different from each other.
