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 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 ...

Instructables user [Simon] admits he addicted to electronics. Lucky for him, his wife of 15 years is pretty cool with, or at least tolerant of his need to fiddle with anything that plugs in. As a gift ...

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 ...

Find a downloadable version of this story in pdf format at the end of the story. EXPONENTIAL GROWTH of LED lighting has ushered in a vast selection of integrated circuit devices to provide controlled ...

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 ...

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.
