When compared with earlier CCFL backlights, using LED TV backlight for Sony offers wider color gamut (with RGB-LED or QDEF) and dimming range and greater contrast ratio. What's more, the backlight is very slim (some screens are less than 0.5 inches (13 mm) thin in edge-lit panels). And also, it's significantly lighter and cooler, as much as half the total chassis and system weight of a comparable CCFL. Typically, it features 20–30% lower power consumption and longer lifespan, which means that the backlight is more reliable.http://www.easternstarcn.com/led-tv-backlight/led-tv-backlight-for-panasonic/
