Digital sign boards, billboards and similar devices used to display text, images, animations or video messages for advertising, information, entertainment and merchandising purposes and most often found in outdoor public areas greatly benefit from the widespread use of LEDs to generate the pixel matrix. For this, it is critical that the high-brightness (HB) LEDs be driven with constant currents and uniformity across the panel to ensure high quality in the image rendering.

We offer a wide range of LED driving solutions optimized for use in large arrays and matrixes that can provide high-efficiency – with our patented power-saving function – and high-accuracy in controlling the current pushed into the LEDs.
