— 36 Channel Output LED Driver Capable of 12 Bit Grayscale PWM Control —
SEOUL, South Korea and SAN JOSE, Calif., Sept. 19, 2018 /PRNewswire/ — MagnaChip Semiconductor Corporation (“MagnaChip Semiconductor”) (NYSE: MX), a designer and manufacturer of analog and mixed-signal semiconductor platform solutions, announced today it now offers a multi-channel Mini LED Driver for the rapidly growing digital signage market, leveraging the company’s more than 10 years of experience with BLU LED drivers in the television set market.
As digital signage and media façades are installed outdoors, the display size can range up to several hundred inches, which requires a much higher level of technology and reliability than found in television sets. For LED panels used in digital signage, about 1,000 LEDs per square meter are used. This results in a situation where the capability of the LED driver must be doubled or even tripled for the most cost-effective scenario. For example, compared with existing LED drivers in the market capable of controlling 12-channel or 16-channel LEDs, MagnaChip’s new Mini LED Driver for digital signage is able to drive 36-channel LEDs concurrently, featuring high density, reduced 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.
Furthermore, MagnaChip’s new mini LED driver differs from competitive products in two important areas. First, a high withstanding voltage of 65Venables surge protection for a high level of security, a key requirement in new LED signage. Second, with regards to LED control and higher reliability, MagnaChip uses a 64 Pin QFN Package (8X8mm^2) to deliver excellent thermal performance and effectively solve the heating issue.
“MagnaChip’s multi-channel LED driver features high efficiency, high contrast, low temperature heat and highly reliable surge voltage characteristics, bringing the benefit of both energy and cost reduction to the entire ecosystem of customers in the long term,” said YJ Kim, CEO of MagnaChip. “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,” he continued.
