A large percentage of LED drivers offered by many vendors use PWM (pulse-width modulation) intensity control to adjust LED brightness for a wide range of applications. In the PWM drivers, the ...

A technical paper titled “Tunnel Junction-Enabled Monolithically Integrated GaN Micro-Light Emitting Transistor” was published by researchers at the Ohio State University and Sandia National ...

In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...

Gallium nitride-based LEDs and power transistors can be made on the same IC, according to scientists from Cornell University and the Polish Academy of Sciences. The trick is to used both sides of the ...

Controlling LEDs is really quite simple. As you know, they need to be current limited which is as easy as applying Ohm’s law to your given set of values. To make things even more even there’s a slew ...

This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

An LED lighting driver chip with in-built 0-10V dimming designed by iWatt does not require a microprocessor to control the dimming function. “We believe this is the first product from anyone with ...

Schematic and operation of a capacitorless active-matrix micro-LED pixel, where a single memristor (1M) substitutes both the storage capacitor and the driving TFT. The compact 1M cell can be ...

Optoelectronics, the use of electronic devices for the detection and control of light, has become a preferred means for broadband and transoceanic communication networks. Below is a sneak peek at the ...

Seeking to keep Moore's Law on pace, researchers have developed a repeatable technique for assembling a single-atom version of the transistor--the building block of semiconductors and computers.

Physicists successfully controlled an electrical current using the "spin" within electrons -- a step toward building an organic "spin transistor": A plastic semiconductor switch for future ultrafast ...
