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 ...

The text explains the science behind diodes and LEDs, their applications, and the breakthroughs that led to the creation of blue LEDs.

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, as demonstrated by researchers from ...

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 ...

A light emitting diode (LED) emits light as electrical current passes through it. LEDs are very small, consumes less electric power and can emit lights of different colors based on the ...

The light emitting diode (LED) market consists of sales of light emitting diode (LED) and related services.It is widely used in backlighting of TV, mobile phones, automotive lighting and display ...

Quantum dot light-emitting diodes A surface-light-emitting device can be fabricated by sandwiching a thin film that is populated with quantum dots between electrodes (Fig. 3).

Of course, the making of organic light-emitting diodes requires more than just a rare-earth metal, not least of which is the experience in the field that [Jeroen Vleggaar] brings to this project.
