For outdoor signage, the size of displays can range up to several hundred inches which use numerous LEDs. Thus, the capability of LED drivers will need to meet the requirement of different sized LED panels. According to MagnaChip, it has developed a new Mini LED Driver for digital signage which is able to drive 36-channel LEDs concurrently with the feature of high density, lower energy consumption and more efficient product designs.

The Mini LED Driver uses 12 Bit Grayscale PWM (Pulse Width Modulation) to enable the 4,000-step PWM control and a sophisticated LED current control. It also provides 64-step output current control, which enables not only detailed graphic representation, but also accurate depictions of a variety of pictures and images according to the brightness of the contents.

YJ Kim, CEO of MagnaChip, said, “MagnaChip is planning to extend the product line for the fast growing segment of digital signage by developing products with an extension of channels and Micro LED Drivers with a high accuracy of LED current based on our new 36 Channel LED Driver."
