CHAMPAIGN, Ill. — A new process for creating ultrathin, ultrasmall inorganic light-emitting diodes (LEDs) and assembling them into large arrays offers new classes of lighting and display systems with ...

You can build a matrix of RGB(red/green/blue) LEDs using a simpleand inexpensive circuit comprising thecontrol logic and driver circuit in Figure 1 and some LEDs (Figure 2). The centerRGB LED is the ...

CFL and LED bulbs are light years ahead of incandescents in the energy efficiency arena. But attractiveness? In most cases, incandescents still win. LEDs are more pleasant than CFLs, but as Yumi Kori, ...

The nighttime twinkling of fireflies has inspired scientists to modify a light-emitting diode (LED) so it is more than one and a half times as efficient as the original. Researchers studied the ...

The increasing use of color displays in portable devices has spurred a number of semiconductor suppliers to develop driver ICs for white LED arrays. Although white LED drivers have been available for ...

Most Christmas lights, DVD players, televisions and flashlights have one thing in common: they're made with light emitting diodes (LEDs). LEDs are widely used for a variety of applications and have ...

A team at Nagoya University has built an iron-based photocatalyst that, when activated by blue LED light, can help assemble complex natural molecules while reducing the amount of expensive chiral ...

Keeping up with new TV tech isn’t easy. Every few years, shoppers see new marketing jargon for features that promise impressive improvements but often don’t live up to the hype. But we’re actually ...

With the exception of the introduction of the energy-saving lightbulbs a few years back, lightbulb technology has not changed too much in 100 years. But General Electric Lighting aims to change that, ...

A new process for creating ultrathin, ultrasmall inorganic light-emitting diodes (LEDs) and assembling them into large arrays offers new classes of lighting and display systems with interesting ...
