ORGANIC LIGHT EMITTING DIODE AND ORGANIC LIGHT EMITTING DEVICE HAVING THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18459303 titled 'ORGANIC LIGHT EMITTING DIODE AND ORGANIC LIGHT EMITTING DEVICE HAVING THEREOF
Simplified Explanation
The present disclosure relates to an organic light emitting diode (OLED) and an organic light emitting device having thereof. The OLED includes an emissive layer with at least one emitting part that includes a green emitting material layer including a first host and a green emitter and a charge control layer including a second host and a dopant of which a maximum luminescence wavelength peak range is longer than a maximum luminescence wavelength of the green emitter. The charge control layer enables the OLED to improve its luminous efficiency, extend its color gamut, and maximize its luminous lifespan.
- Green emitting material layer with a first host and a green emitter
- Charge control layer with a second host and a dopant for improved efficiency
- Maximum luminescence wavelength peak range longer than green emitter's wavelength
- Improved luminous efficiency, extended color gamut, and maximized luminous lifespan
Potential Applications
The technology can be applied in:
- Display screens
- Lighting applications
- Wearable technology
Problems Solved
- Improved luminous efficiency

Unanswered Questions
How does the charge control layer specifically improve luminous efficiency?
The charge control layer helps to better manage the flow of charges within the OLED, leading to more efficient light emission.
What are the specific factors that contribute to extending the color gamut of the OLED?
The use of the dopant in the charge control layer, with a longer maximum luminescence wavelength peak range, allows for a wider range of colors to be displayed by the OLED.
