The largest commercially available LCD TV in the World.
World’s first adoption of innovative Local Dimming Technology, which enables it to deliver a dynamic contrast ratio 500,000:1 and lower power consumption by as much as 50%
Samsung Electronics Co., Ltd. has introduced the largest (70 inch) commercially available full high-definition LCD TV in Korea. The new TV boasts Samsung's very best image enhancement technologies and employs a light-emitting diode (LED) backlight instead of the conventional cold cathode fluorescent lamp (CCFL) version. Moreover, Samsung's unique local dimming technology enables the LED backlight to be turned off in dark image areas, delivering a dynamic contrast ratio of 500,000:1. At the same time, power consumption is lowered by as much as fifty percent.
Terminologi :
- 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.
Samsung plans to put the product on sale worldwide in the second half of this year. (Source : Samsung)
