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

This abstract first appeared for US patent application 17842448 titled 'LIGHT-EMITTING DEVICE AND ELECTRONIC APPARATUS INCLUDING THE SAME

Simplified Explanation

Abstract: A light-emitting device is described in this patent application. The device includes an interlayer that contains a contact layer consisting of an electron-transporting host and a hole-transporting host. The contact layer is directly in contact with an emission layer, which comprises a first dopant and a second dopant.

Patent/Innovation Explanation:

  • The patent application describes a light-emitting device that incorporates an interlayer with a specific contact layer composition.
  • The contact layer consists of an electron-transporting host and a hole-transporting host, which facilitate the movement of electrons and holes within the device.
  • The contact layer is in direct contact with the emission layer, which contains two different dopants.
  • The combination of the contact layer and the emission layer enables efficient light emission from the device.

Potential Applications:

  • This technology can be used in the manufacturing of light-emitting diodes (LEDs) for various applications.
  • It can be applied in display technologies, such as OLED (organic light-emitting diode) displays, to enhance their performance.
  • The light-emitting device described in the patent application can find applications in lighting systems, signage, and other illumination devices.

Problems Solved:

  • The technology addresses the challenge of efficient electron and hole transport within a light-emitting device.
  • By incorporating a specific contact layer composition, the patent application aims to improve the overall performance and efficiency of the device.
  • The use of two different dopants in the emission layer can enhance the color range and brightness of the emitted light.

Benefits of the Technology:

  • The described light-emitting device can provide improved efficiency and performance compared to existing devices.
  • The specific contact layer composition enables efficient electron and hole transport, leading to enhanced device operation.
  • The incorporation of two different dopants in the emission layer allows for a wider range of colors and increased brightness in the emitted light.
