In Part 1 of this two-part series, “Creating Uniform LED Luminescence in RGB Displays”, the discussion focused on dot correction. This design technique is used for managing individual pixel brightness ...

Santa Clara, Calif. — National Semiconductor Corp. says it has introduced the industry's first common-anode, current-mode, high-brightness light-emitting diode (LED) driver with pulse-width modulation ...

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 ...

Usually, an MCU is considered a digital device. By default, its output voltage level can be either high or low and nothing in between. With the requirement to create an LED brightness control, the ...

Most of us are aware that charlieplexing can drive a large number of LEDs from a relatively small number of I/O pins, but [David Johnson-Davies] demonstrates adding another dimension to that method to ...

MILPITAS, Calif., May 08, 2023 (GLOBE NEWSWIRE) — Lumissil Microsystems, a division of Integrated Silicon Solution, Inc. (ISSI), announces the release of its latest 48-channel LED driver with a ...

White LEDs (WLED) are increasingly becoming the light source of choice for backlighting applications due to their attractiveness in power efficiency and form factor. Display solutions in portable ...

High-power industrial Light Emitting Diode (LED) fixtures use series-parallel strings of High Brightness (HB) LEDs to produce superior lighting fixtures compared to traditional, "ballast-based" ...

Used in industrial, architectural, and automotive applications, as well as for warning lamps and emergency lights, high-brightness power LEDs (HBLEDs) are becoming more and more popular, due in part ...

This module introduces Pulse Width Modulation (PWM) techniques for Python on the Raspberry Pi. Subsequently, by using PWM we can modify the brightness of an LED without having to change a resistor.
