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 20240179933 titled 'ORGANIC LIGHT EMITTING DIODE AND ORGANIC LIGHT EMITTING DEVICE HAVING THEREOF
Simplified Explanation
The present disclosure is about an organic light emitting diode (OLED) and an organic light emitting device. The OLED includes an emissive layer with a green emitting material layer and a charge control layer to improve luminous efficiency, extend color gamut, and maximize luminous lifespan.
- Green emitting material layer:
- Includes a first host and a green emitter
- Charge control layer:
- Includes a second host and a dopant with a longer maximum luminescence wavelength peak range than the green emitter
Potential Applications
This technology could be used in:
- Display panels
- Lighting fixtures
- Wearable technology
Problems Solved
- Improved luminous efficiency
- Extended color gamut
- Maximized luminous lifespan
Benefits
- Enhanced display quality
- Energy efficiency
- Long-lasting performance
Potential Commercial Applications
- Consumer electronics
- Automotive lighting
- Architectural lighting
Possible Prior Art
One possible prior art could be the use of different host materials in OLEDs to improve performance.
Unanswered Questions
How does the charge control layer specifically improve luminous efficiency?
The charge control layer helps to optimize the movement of charges within the OLED, leading to more efficient light emission.
What is the specific mechanism behind extending the color gamut with this technology?
The charge control layer with a dopant of longer maximum luminescence wavelength peak range helps to broaden the range of colors that can be displayed by the OLED.
Original Abstract Submitted
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.
