An LED-backlight LCD television is an LCD TV that uses LED backlighting instead of the CCFLs used in traditional LCD televisions. It is not a true LED display but is called "LED TV" by some manufacturers.[1] The use of LED backlighting has a dramatic impact, resulting in a thinner panel, less power consumption and better heat dissipation, and a brighter display with better contrast levels.
The LEDs can come in three forms:
- Dynamic RGB LEDs which are positioned behind the panel
- White Edge-LEDs positioned around the rim of the screen using a special diffusion panel to spread the light evenly behind the screen (the most common)
- A full-array of LEDS which are arranged behind the screen but are incapable of dimming or brightening individually
