There’s a new type of LED in town. These light-emitting diodes (LEDs) are made from a material called perovskite, a calcium ...

An upconversion organic light-emitting diode (OLED) based on a typical blue-fluorescence emitter achieves emission at an ultralow turn-on voltage of 1.47 V. The technology circumvents the traditional ...

Engineers from Seoul National University and other labs are quietly redrawing what household lighting could look like, ...

A research team has successfully synthesized a new class of helical quinolizinium salts exhibiting exceptionally strong fluorescence in the orange-to-red light region (606–682 nm). Smart glasses that ...

Use of copper as a fluorescent material allows for the manufacture of inexpensive and environmentally compatible organic light-emitting diodes (OLEDs). Thermally activated delayed fuorescence (TADF) ...

What Is A Light-Emitting Diode? A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. LEDs function by converting electrical current into ...

OLEDs are also commonly referred to as organic LEDs and organic electroluminescent diodes. They operate due to the phenomenon of electroluminescence. A thin organic film is sandwiched between two ...

Researchers have developed an improved organic light emitting diode (OLED) sealing process to reduce moisture intrusion and improve device lifetime. They are using advanced ion assisted deposition to ...

Organic light-emitting diodes (OLEDs) use layers of organic molecules to efficiently convert electricity into light. The molecules, though great emitters, are generally poor electrical conductors, so ...

LED lightbulbs are more energy-efficient than standard bulbs, but that doesn't mean they work perfectly all of the time. Here's how to troubleshoot these bulbs.
