Samsung Electronics said on Monday that they developed the world?s slimmest 40 inch LCD panel, which records 3.9 millimeters in width.

The product adopted LED backlights installed at the edge of a panel, allowing for an overal width of just 3.9mm - only a third of the currently available slimmest panel which records 10.8 millimeters in width. A panel used in TV sets is usually 2 millimeters in width before the backlight unit is added. Samsung said that it used its own ultra slim panel designing technology, newly developed major parts and renewed the design of the backlight unit.

The 40-inch TV also maintains the same level of high-definition quality, according to Sansung. It offers a full HD resolution, 120Hz and a contrast of 5,000 to 1.

In October 2008, Samsung developed the world's slimmest liquid crystal display (LCD) panel, at 7.9mm thick.

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