Lots of modern phones use pulse width modulation, or PWM, to manage brightness. But what is PWM, why is it harmful, and what can you do about it? We give you all the details.

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 ...

The TPS7510x linear low dropout (LDO) matching LED current source is optimized for low power keypad and navigation pad LED backlighting applications. The device provides a constant current to up to ...

While all of my own devices and monitors don't have PWM dimming for their backlighting, there are some monitors at work which do appear to use PWM. Now many of these monitors are years old, and I ...

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 ...

High-brightness LEDs (HBLEDs) are making inroads into more traditional lighting applications that include a dc distribution system (for example, 24-V MR-16 track lights). HBLEDs are more efficient, ...

Pulse Width Modulation is definitely the preferred method of dimming an LED with a microcontroller, but we were interested in hearing about a different method called Binary Code Modulation. BCM does ...

According to a new report, Google is finally addressing a long-standing shortcoming of Pixel displays by adjusting the PWM refresh rate on its Pro phones this year, while upgrading the brightness ...

With the launch of the Galaxy S26 series, Samsung has grabbed headlines thanks to its new Privacy Display technology on the S26 Ultra. While it’s an interesting ...
