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 ...

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

Quantum dot light-emitting diodes (QLEDs) are paving the way for them to emerge as the leading technology in next-generation solid-state lighting and flat panel display. Additionally, the stringent ...

Light-emitting diode (LED) light therapy is a cosmetic and medical treatment that uses LED wavelengths to treat various skin conditions, such as acne and psoriasis. You can get this therapy at a ...

Together, they make the white light you see when the sun -- the main source of blue light -- is shining. Fluorescent and LED (light-emitting diode) light bulbs also give off blue light.

LED, or light-emitting diode, therapy was developed by NASA scientists in the early 1990s, first for plant growth experiments in space and later to boost astronauts’ wound healing.
