Samsung unveils 57-inch TFT LCD panel

Samsung Electronics has developed a 57-inch liquid crystal display (LCD) panel, the largest such panel in the world.

The panel was produced on the company's new fifth-generation thin film transistor (TFT) LCD production line that began operation in September. The largest panel possible to be manufactured is governed by the size of glass sheet that a production line can handle. Fifth-generation lines can accept glass up to 110cm by 130cm making the 57-inch panel possible, Samsung said.

There were no plans to begin mass production of the panel, which was developed mainly to demonstrate and test the technology for such size screens, a spokesperson for Samsung, said.

The company has also yet to begin mass production of a 54-inch panel announced last year.

Samsung currently offered a 46-inch panel as its largest commercial product, she said.

The 57-inch panel has a resolution of 1920 pixels x 1080 pixels matching that required for wide-screen high-definition television. Other attributes include a 1000:1 contrast ratio, 600 candela per square metre brightness level, maximum 8 milliseconds response time and 75 per cent colour reproduction.

The panel itself measures 132.3cm x 76.5cm, is 4.75cm thick and weighs 21.5kg. Power consumption is 350 watts at maximum brightness.

The company did not release any pricing estimates for what such a panel might cost when or if mass production begins, however Park said a television set based on one of its 40-inch panels cost about $US5000. Panel prices were currently in the $US100-per-inch range.

In October, Samsung broke ground on construction of a seventh-generation LCD production line at its facility Tangjeong, south of Seoul. The line can handle glass up to a maximum size of 187cm x 220cm and is expected to begin mass production in mid-2005.

It will be used by a joint venture the company plans to form with Japan's Sony.
