OLED and QLED TVs show a significant difference in image contrast, color fidelity, and brightness. Choosing the right one ...

Researchers have shown that the coronavirus can be killed efficiently, quickly, and cheaply using ultraviolet (UV) light-emitting diodes (UV-LEDs). They believe that the UV-LED technology will soon be ...

To be more energy efficient, many people have replaced their incandescent lights with light-emitting diode (LED) bulbs. However, those currently on the market emit a lot of blue light, which has been ...

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.

Scientists from the Korea Institute of Energy Research (KIER) have developed a grid-type light-emitting diode (LED) display with reflective walls that can be used in combination with ...

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 ...

UC Berkeley chemists created a type of halide perovskite crystal that emits blue light, something that has been hard to achieve with this trendy new material. But the researchers discovered that these ...

LED bulbs are known for longevity, but how you use them plays a larger role than many realize, and small details can quietly ...

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 ...

British inventors began experimenting with electric lighting in the 1830s, working on so-called arc lamps, while other scientists around the world focused on developing a functioning incandescent lamp ...
