Samsung unveils 57-inch TFT LCD panel

Samsung Electronics has developed a 57-inch liquid crystal display panel, claimed to be the largest such panel in the world.

Samsung Electronics has developed a 57-inch liquid crystal display panel, claimed to be the largest such panel in the world.

The panel was produced on the company's fifth-generation TFT LCD production line which began operation in September. The line can accept glass up to 110cm by 130cm, making the 57-inch panel possible.

There are no plans to begin mass production of the panel, which was developed mainly to demonstrate and test the technology for such size screens, said Samsung spokeswoman Park Sung Hae.

Samsung has yet to begin mass production of a 54-inch panel announced last year. At present, offers a 46-inch panel as its largest commercial product.

The 57-inch panel has a resolution of 1,920 pixels by 1,080 pixels, matching that required for widescreen, high-definition television. Other attributes include a 1000:1 contrast ratio, 600 candela per square metre brightness level, maximum eight milliseconds response time and 75% colour reproduction.

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

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

The line will be used by a joint venture the company plans to form with Sony.
