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

A process developed at ETH Zurich enables the massive miniaturisation of organic light-emitting diodes (OLEDs) in only one single step. The light sources are now smaller than the wavelength of the ...

Tokyo, Japan – Scientists from Tokyo Metropolitan University have developed a new electrode material for deep-ultraviolet (DUV) light-emitting diode applications. They used a cutting-edge deposition ...

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 ...

The evolution of LED technology has led to the development of several types, primarily inorganic LEDs, OLEDs, and QLEDs. Inorganic LEDs are known for their durability and energy efficiency, making ...

Scientists from the Korea Institute of Energy Research (KIER) have developed a grid-type light-emitting diode (LED) display with reflective walls that can be used in combination with ...
