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 ...

Colloidal quantum dots (QDs) exhibit exceptional properties of narrow-band emission, tunable luminescent wavelength, high luminous efficiency, and remarkable material stability across the visible and ...

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 ...

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 ...

Jeong Cheol-dong, president of LG Display, met with reporters at CES 2026 in Las Vegas on the 5th (local time) and said, “In ...

PeLEDs have been considered the most potential application technologies for the next-generation display and lighting field. Since the first room temperature-emission PeLED was demonstrated in 2014, ...
