Samsung shows us the 70-inch large Full-HD LCD TV which features the Local Dimming Technology. The Local Dimming Technology offers “a dynamic contrast ratio 500,000:1 and lower power consumption by as much as 50%”.

Samsung’s 70-inch Full HD LCD TV is the largest commercially available LCD TV in the World. It features also the light-emitting diode (LED) backlight.

Local dimming backlighting : The conventional, bar-shaped CCFL backlight is replaced by an LED backlight consisting of hundreds of light source. The lit parts of the on-screen image can brightened to the maximum while all light is shut off in the dark areas of the screen. The result is the ultimate contrast ratio. Moreover, the reduction of brightness in the dark areas also cuts power consumption by as much as half.

LED scanning : The LEDs are rapidly shut off in sequence, artificially eliminating the ghosting of the moving images.
