Samsung edge-lit LED
Samsung has begun mass production of ultra-slim LCD panels for its upcoming large size TVs. Edge-lit LED backlighting is designed to reduce component weight while allowing a thinner overall profile. The company claims the new panels are just 10.8 mm thick, compared to conventional LCDs in the 40-inch, 46-inch and 55-inch sizes that are approximately four times thicker.
Edge-lit systems emit light from a row of LEDs on the top and bottom of every panel, as opposed to direct-lit configurations that project light forward across the entire screen from the front. The edge-lit technology gathers light toward the center of the display and redirects it using light-guide plates for focus.
Along with the potential for improved aesthetic appearance, LED backlighting is said to consume up to 40 percent less power than standard LCDs using cold cathode fluorescent lamp (CCFL) technology. The electronics are also mercury free.
