LED DESIGN FORUM: Driver IC design ensures optimum performance of LED backlighting (MAGAZINE)
LED backlight drivers are the “wizards behind the curtain” that ensure a display’s visual performance will remain as specified regardless of the operating conditions, says Michael Jennings.
The potential advantages LEDs have over CCFLs are formidable: they consume less power, last about five times longer, are more efficient, can reduce display thickness, are dimmable in fine steps, use low-voltage drivers and do not contain mercury and other hazardous substances as do CCFLs. However, it’s important to remember that behind every successful LED-enabled backlighting application are driver ICs that optimize the performance of the LEDs, protect them from a wide range of potentially damaging scenarios and ensure consistent visual quality over the life of the display.
