ORGANIC LIGHT EMITTING DIODES AND ORGANIC LIGHT EMITTING DEVICES - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240224570 titled 'ORGANIC LIGHT EMITTING DIODES AND ORGANIC LIGHT EMITTING DEVICES

Simplified Explanation: This patent application discloses an organic light emitting diode (OLED) and an organic light emitting device that includes the OLED, such as a display device or a lighting device. The device includes an emissive layer with a charge control layer that helps improve the luminous efficiency of both red and blue lights.

  • The OLED includes a charge control layer with controlled hole mobility and/or a homo energy level between a red emitting material layer and a blue emitting material layer.
  • By injecting holes and electrons into the emitting material layer in balance, the blue luminous efficiency can be improved, and an exciton recombination zone is formed within the emitting material layer.
  • The balance of luminous efficiency between red and blue lights results in beneficial blue luminous efficiency and excellent red luminous efficiency.

Key Features and Innovation:

  • Emissive layer with a charge control layer for improved luminous efficiency.
  • Controlled hole mobility and homo energy level between red and blue emitting material layers.
  • Formation of exciton recombination zone within the emitting material layer.
  • Balance of red and blue luminous efficiency for optimal performance.

Potential Applications: This technology can be used in display devices, lighting devices, and other applications that require efficient and high-quality lighting.

Problems Solved: This technology addresses the challenge of improving the luminous efficiency of both red and blue lights in OLEDs.

Benefits:

  • Improved blue luminous efficiency.
  • Excellent red luminous efficiency.
  • Enhanced overall performance of OLED devices.

Commercial Applications: Potential commercial applications include OLED displays, lighting fixtures, and other devices that require high-quality lighting solutions.

Prior Art: Prior art related to this technology may include research on OLEDs, charge control layers, and luminous efficiency optimization in organic light emitting devices.

Frequently Updated Research: Researchers are constantly exploring new materials and techniques to further improve the efficiency and performance of OLEDs.

Questions about OLED Technology: 1. How does the charge control layer in OLEDs contribute to improving luminous efficiency? 2. What are some potential challenges in balancing the luminous efficiency of red and blue lights in OLED devices?


Original Abstract Submitted

an organic light emitting diode (oled) and an organic light emitting device including the oled (e.g., a display device or a lighting device) are disclosed herein. an emissive layer disposed between two electrodes includes a charge control layer with controlled hole mobility and/or a homo energy level between a red emitting material layer and a blue emitting material layer. the blue luminous efficiency can be improved and exciton recombination zone is formed within an emitting material layer by injecting holes and electrons into the emitting material layer in balance. as the luminous efficiency of red and blue lights is controlled in balance, beneficial blue luminous efficiency and excellent red luminous efficiency can be realized.
