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.
