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 ...

Adaptive brightness control has become a common feature in modern smartphones, HDTVs, PDAs, tablets, and computer screens. The goal of this feature is to conserve power as well as to make the display ...

Light emitting diodes (LEDs) deliver emitted light in response to current being made to flow through them, but then you already knew that, right?? If we define that the light output of an LED is ...

Most engineers are quite familiar with typical low-power-indicator LEDs, whether they be surface-mount or the classical through-hole packages. All that's needed to use them is a voltage source and a ...

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 ...

The IS32LT3959 is a single inductor, multi-topology controller with constant on-time for driving a ground referenced high-voltage LED string. This single channel switching LED driver integrates a PWM ...

The C7L, C8L and flagship X11L represent TCL's most ambitious push into the premium TV segment yet, built around a display ...

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 ...
