Samsung delivers world's largest commercially available LCD TV

Samsung aims to impress with the retail launch of its new 70" LCD TV in Korea. The new Samsung  LN70F91BD forgoes the traditional CCFL backlight in favor of an LED backlight for improved picture clarity.

"I am pleased to introduce the 70" Full-HD LCD TV with innovative Local Dimming Technology," said Samsung Digital Media President JongWoo Park. "Samsung will continue to strengthen its LCD TV leadership, enhancing Full-HD and large screen LCD TV line-up.

Also new to the TV is what Samsung calls "local dimming backlighting." Since the backlight consists of hundreds of LED elements, an image displayed on the screen can range from maximum brightness (LEDs at full power) to complete darkness to produce true black (LEDs turned completely off). This differs from traditional CCFL LCDs where black levels can appear more grayish.

Samsung says that the use of the LED backlight gives the LCD TV a dynamic contrast ratio of 500,000:1 while power consumption is cut by as much as 50 percent. According to AVING, the LN70F91BD features ACAP, three HDMI 1.3 port and a USB 2.0 port.

Samsung's 1080p 70" LCD TV is on sale now in Korea for 59 million won ($63,425 USD) and will be available worldwide during the second half of 2007.





"We are going to continue to work with them to make sure they understand the reality of the Internet.  A lot of these people don't have Ph.Ds, and they don't have a degree in computer science." -- RIM co-CEO Michael Lazaridis
