For most of their history, the LCD screens used for digital signage have incorporated cold cathode fluorescent light (CCFL) tubes to illuminate the image. But that’s changing. LED-backlit screens are poised to take the lead when it comes to digital signage in the commercial space.
LED-backlit displays offer a host of advantages over CCFL-backlit displays, including a longer lifespan, a cleaner image and lower energy consumption. LED backlighting has the potential to reshape the way commercial digital signage is deployed.
