Organic light-emitting diodes (OLEDs) are widely used in smartphones and TVs thanks to their excellent color reproduction and ...

The organic light emitting diodes—known widely as OLEDs—that create vibrant smartphone displays could illuminate rooms, but ...

A new type of OLED can generate left- or right-handed circularly polarized light from just one form of light-emitting ...

Living bacteria embedded in silicone can absorb green LED light and re-emit it as red, offering a potential sustainable ...

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 ...

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 ...

Light-emitting diode bulbs (LEDs) are energy-efficient and durable options. LEDs convert electricity into light instead of ...

The TSHF5211, an 890-nm infrared emitting diode from Vishay, delivers a typical radiant intensity of 235 mW/sr at a drive current of 100 mA. According to the manufacturer, this represents a 50% ...

We might tend to take the word “diode” for granted if we’re thinking of a “diode” as just a two-lead or two-terminal device that gets used in this or that place for this or that purpose. It can become ...
