A unique mechanical design aspires to remove heat from this LED light bulb’s insides, but you still need to keep external ventilation in mind.

In an effort to create simpler next-generation lighting solutions, researchers from the University of Turku in Finland have developed a color-tunable white OLED. It is a top light-emitting device that ...

A new water-integrated droplet electricity generator produces high electrical output while floating on water surfaces. Raindrops are not only a source of fresh water, they also carry unused energy ...

Abstract: The state-of-the-art micro-LEDs based on group III-V chips face the challenges in size-effect and mass transfer. Recently, perovskite LEDs have rapidly developed, and their solution ...

The numbers you see on the box don't always work out in real life. LED bulbs do last longer, but those claims about five to 10 years are estimates based on internal testing -- and companies are always ...

A deep blue organic light-emitting diode (OLED) developed by researchers at Science Tokyo operates on just a single 1.5 V, overcoming the high-voltage and color-purity problems that have long limited ...

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 ...

Abstract: Reducing the driving voltage of blue organic light-emitting diodes (OLEDs) is an essential issue for saving display energy. In this study, a novel combination of blue-emitting material and ...

Perovskite has broad application prospects in solar cells, light-emitting diodes (LEDs), and detectors due to its high luminescent efficiency and low cost. However, electrons and holes in traditional ...

Scientists have developed an ultra-thin, paper-like LED that emits a warm, sunlike glow, promising to revolutionize how we light up our homes, devices, and workplaces. By engineering a balance of red, ...
