Samsung’s “Needle Slim,” a 3.9mm thin 40” Full HD LED Backlight TV, featureing a 120Hz LCD panel and a 5000:1 contrast ratio is now the world’s thinnest LCD TV.

A panel used in TV sets is usually 2 millimeters in width before the backlight unit is added. There has been a technical issue in making it 3 millimeter slim. Samsung Electronics used its own ultra slim panel designing technology, newly developed major parts and renewed the design of the backlight unit. It decided to use an edge-type LED backlight while combining its manufacturing technologies for optical film and ultra-slim panels.

Samsung Electronics plans to unveil this ultra-slim panel at the FPD International 2009 scheduled to open on October 28 in Yokohama.
