[Tim] recently found himself tinkering with a cheap string of LEDs. Far from an advanced, IC-controlled addressable set, these were merely a string with LEDs of four colors that could be switched on ...

Light-fingered printing technique could point the way forward for LEDs A team of researchers in the US has developed a new technique to shrink the size of inorganic LEDs so they can be used as pixels ...

Korean researchers have reported an in-situ passivation strategy for pure-blue perovskite LEDs (PeLEDs), opening up the ...

Machine-vision systems use very short flashes of intense light to produce high-speed images employed in a wide variety of data-processing applications. For instance, fast-moving conveyor belts are run ...

Spurred by the increasing cost of energy and concerns about climate change, governments and industry are pushing for higher-efficiency lighting. HB LEDs (high-brightness light-emitting diodes) provide ...

Over the years as I've built new PCs I've kept the motherboards from the replaced machines and hung them on the wall. A little bit of geeky artwork. I've decided to dress them up a bit and put them in ...

There are many power management methods that can be used for LED lighting. You can drive them via a number of dedicated driver ICs available on the market, or even use microcontroller units (MCUs) for ...

LED-based video screens and signage (VSS) are ubiquitous today – from billboards to road marking to stadium screens. LED displays are usually split into two categories: indoor and outdoor. Indoor ...
