A Thermally Stable Organic Light-Emitting Diode

1995
The design of organic electroluminescence (EL) devices meets several barriers, thermal stability and injection ability of charge carriers from the electrodes being important examples. In spite of considerable efforts to surmount them,1 they still create serious problems and require more experimental data and profounded knowledge on the device operation.

Models of organic light-emitting diodes

Synthetic Metals, 1997
Abstract Based upon the recognition that bimolecular charge recombination in random organic systems is in accord with the Langevin formalism, a simple model has been developed to treat the recombination of charge carriers in light-emitting diodes (LEDs).

Recent Progress of Singlet‐Exciton‐Harvesting Fluorescent Organic Light‐Emitting Diodes by Energy Transfer Processes

Advances in Materials, 2019
The external quantum efficiency (EQE) of organic light‐emitting diodes (OLEDs) has been dramatically improved by developing highly efficient organic emitters such as phosphorescent emitters and thermally activated delayed fluorescent (TADF) emitters ...

Built‐In Haze Glass‐Fabric Reinforced Siloxane Hybrid Film for Efficient Organic Light‐Emitting Diodes (OLEDs)

Advanced Functional Materials, 2018
Substrates with high transmittance and high haze are desired for increasing the light outcoupling efficiency of organic light‐emitting diodes (OLEDs). However, most of the polymer films used as substrate have high transmittance and low haze.

Organic Light-emitting Diodes

2014
Organic light-emitting diodes (OLEDs) are another type of LED and have a more recent history, with origins in the 1950s. The demand for cheap, compact and low-power consuming light sources for displays in the increasing range of consumer products and electronic devices helps to drive research and development in light-emitting diodes, quantum dots and ...

Light Emitting Efficiencies in Organic Light Emitting Diodes (OLEDs)

2001
The interface between the organic layer and metallic anode of an OLED is crucial to the stability and the performance of the device. The α-septithiophene (α-7T) has been used as the buffer layer at the interface between the ITO electrode and the hole transport layer (HTL).
