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 ...

Light can be produced and/or controlled electronically in a number of ways. Among the widely used of all the different types of semiconductor diodes are the Light Emitting Diodes or LEDs. It is a PN ...

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 ...

Perovskite LEDs with the world's highest efficiency (EQE = 23.4%) -- Seoul National University and University of Pennsylvania Research team at Seoul National University (Prof. Tae-Woo Lee) and ...

Engineers in Switzerland have built light-emitting diodes so small that hundreds could line up across the width of a single human cell, shrinking a core component of modern electronics to a scale that ...

LED lighting technology is increasingly adopted for its energy efficiency, durability, and longevity, making it an ideal solution for modernizing urban areas and developing smart city infrastructures.

This illustration depicts the QAO family dopant integrated into the organic light-emitting diode structure. By designing a molecule with a lower HOMO level than that of the host material, the ...

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 ...
