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 ...

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 ...

Researchers have found a new way to simplify the structure of high-efficiency blue organic light-emitting diodes (OLEDs), which could lead to longer-lasting and higher definition television screens.

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 ...

Wearable electronics have evolved from basic fitness trackers to sophisticated health-monitoring systems, demanding light-emitting devices that balance visual quality, power efficiency, and mechanical ...

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.
