An LED-backlit LCD is a flat panel display that uses LED backlighting instead of the cold cathode fluorescent (CCFL) backlighting used in most other LCDs. The use of LED backlighting allows for a thinner panel, lower power consumption, better heat dissipation, a brighter display, and better contrast levels. LED backlit LCD TVs use the same TFT LCD technologies as CCFL backlit LCD TVs. Picture quality is primarily based on TFT LCD technology independent of backlight type. While not an LED display, a television using this display is called an “LED TV”.
LED backlit LCDs are not self-illuminating, unlike pure LED systems. There are several methods of backlighting an LCD panel using LEDs, including the use of either white or RGB (Red, Green, and Blue) LED arrays behind the panel, and edge-LED lighting, which uses white LEDs arranged around the inside frame of the TV and a light diffusion panel to spread the light evenly behind the LCD panel.
