ORGANIC ELECTROLUMINESCENT DEVICE EMITTING GREEN LIGHT - A simplified explanation of the abstract
This abstract first appeared for US patent application 17628766 titled 'ORGANIC ELECTROLUMINESCENT DEVICE EMITTING GREEN LIGHT
Simplified Explanation
The present invention is about an organic electroluminescent device that includes a light-emitting layer B. This layer consists of a host material H, a thermally activated delayed fluorescence (TADF) material E, and a small full width at half maximum (FWHM) emitter S. The TADF material E transfers energy to the emitter S and emits light in the wavelength range of 500 nm to 560 nm.
- The invention is an organic electroluminescent device with a specific light-emitting layer composition.
- The light-emitting layer includes a host material, a TADF material, and a small FWHM emitter.
- The TADF material transfers energy to the emitter and causes it to emit light in a specific wavelength range.
Potential applications of this technology:
- Display devices such as OLED screens.
- Lighting applications.
- Signage and advertising displays.
Problems solved by this technology:
- Improved efficiency and brightness of organic electroluminescent devices.
- Enhanced color range and accuracy in displays.
- Reduction in power consumption.
Benefits of this technology:
- Higher efficiency and brightness compared to traditional organic electroluminescent devices.
- Expanded color range and improved color accuracy.
- Lower power consumption, leading to energy savings.
Original Abstract Submitted
The present invention relates to a an organic electroluminescent device comprising at least one light-emitting layer B comprising at least one host material H, at least one thermally activated delayed fluorescence (TADF) material E, and at least one small full width at half maximum (FWHM) emitter Swherein Etransfers energy to Sand Semits light with an emission maximum in the wavelength range from 500 nm to 560 nm.
