White LEDs used in backlighting provide illumination for the pixels in liquid crystal displays. The LEDs are typically routed on one or two sides of the displays light diffuser, and biased with 20 mA ...

This article will explain the basic operation and configuration of a simple parallel strings LED driver. Examples and illustrations are also shown for better understanding together with its advantages ...

Sony says that Crystal LED will be developed in “parallel” to OLED for future consumer and professional applications. Sony says that Crystal LED will be developed in “parallel” to OLED for future ...

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 ...

Several driver options are at the fingertips of designers with the FAN56XX family of LED drivers from Fairchild Semiconductor. For instance, driver-only parallel connection drivers with no boost ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...

[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 ...

Hello,<P>I am making a custom-built, welded aluminum case. I have several different color LED's that I would like to use, and would like to hook 3 LED's up to one lead. Normally when the IDE channel ...

[Henryk] just sent us his latest episode of simple LED circuit puzzles. In front of the camera he solders one pin of each of the 3 LEDs to a different switch. He then puts the three assemblies in his ...
