The Constant Current Backlight Driver Board is a precision circuit designed specifically for LED backlight strips, whether connected in series or in arrays. It ensures a stable current to each LED, unaffected by voltage fluctuations or component inconsistencies, thereby delivering uniform, stable, and long-lasting screen backlighting. This solution is widely used in large-format LCDs, advertising light boxes, digital signage, and other display systems that demand high stability and long service life of backlighting.
