LIGHT-EMITTING DEVICE AND ELECTRONIC APPARATUS INCLUDING THE LIGHT-EMITTING DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18053152 titled 'LIGHT-EMITTING DEVICE AND ELECTRONIC APPARATUS INCLUDING THE LIGHT-EMITTING DEVICE

Simplified Explanation

The abstract describes a light-emitting device that consists of two electrodes and an interlayer with an emission layer in between. The emission layer is composed of two sub-layers: a first emission layer with a phosphorescent emitter and a first host, and a second emission layer with a fluorescent emitter and a second host. The phosphorescent emitter emits blue light with a specific emission spectrum.

  • The light-emitting device includes a first electrode, a second electrode, and an interlayer with an emission layer.
  • The emission layer consists of a first emission layer and a second emission layer.
  • The first emission layer contains a phosphorescent emitter and a first host.
  • The second emission layer contains a fluorescent emitter and a second host.
  • The phosphorescent emitter emits blue light with a specific emission spectrum.

Potential applications of this technology:

  • Lighting: The light-emitting device can be used for general lighting purposes, providing efficient and high-quality blue light.
  • Displays: The device can be utilized in displays, such as OLED screens, to enhance color accuracy and brightness.
  • Signage: The technology can be applied in illuminated signs, ensuring vibrant and long-lasting blue light.

Problems solved by this technology:

  • Efficient blue light emission: The use of phosphorescent and fluorescent emitters allows for efficient and specific blue light emission, addressing the challenge of achieving high-quality blue light in light-emitting devices.
  • Color accuracy: The combination of phosphorescent and fluorescent emitters with different hosts enables precise control over the emission spectrum, resulting in improved color accuracy in lighting and display applications.

Benefits of this technology:

  • Energy efficiency: The phosphorescent and fluorescent emitters enhance the overall energy efficiency of the light-emitting device, reducing power consumption.
  • Enhanced color quality: The specific emission spectrum of the blue light emitted by the device ensures high color quality and accuracy.
  • Versatility: The ability to combine different emitters and hosts in the emission layer allows for customization and adaptation to various lighting and display requirements.


Original Abstract Submitted

A light-emitting device including a first electrode, a second electrode facing the first electrode, and an interlayer arranged between the first electrode and the second electrode and including an emission layer is provided. The emission layer includes a first emission layer and a second emission layer. The first emission layer includes a phosphorescent emitter and a first host. The second emission layer includes a fluorescent emitter and a second host. The phosphorescent emitter is configured to emit a first light having a first emission spectrum, and the first light is blue light.
