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 ...

In the previous chapter, we stored the current state in a variable and switched the LED operation mode every time the button was pressed.The signals sent to the LED so far have been of two types: HIGH ...

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 ...

How a single LED driver can support buck, boost, and buck-boost topologies. Design details for each topology type. How such drivers work in automotive and machine-vision designs. The breadth of LED ...

The ESP32 has two PWM hardware implementations. One is intended for use in motor control and has extra features such as a dead zone and auto-braking. The second, LEDC, is specifically designed to ...

However LEDs are dimmed – be it by 1 – 10 V analogue voltage, mains phase angle, power-line, digital inputs such as DALI, or a WLAN link, there is in fact only two ways to actually dim the output of a ...

Have you ever looked at your phone and gotten a headache? Sometimes, it just means you've been on it too long and need to take a break. For some folks like me, it's the display itself that's causing ...

The smartphone has become a constant companion for many people. Studies say that on average we turn on the smartphone 88 times per day and look at it for 3.25 hours per day. This means that the screen ...

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" ...

Infineon has brought out an LED driver IC with a hybrid dimming mode technology for achieving 0.5% of the target current. With its supply voltage range from 8 V DC up to 80 V DC, the driver IC ...
