Samsung Develops World’s Largest (82”) Full HDTV TFT-LCD
Samsung Electronics has unveiled its 82-inch TFT-LCD at CeBIT 2005, which opened in Hannover, Germany on 10th March.
The world’s largest TFT-LCD, the full HD image quality 82” TFT-LCD panel was developed at the company’s new seventh generation production complex in Tangjeong, Korea. Over the years, Samsung has made a series of breakthroughs in TFT-LCD technology ahead of the competition. Samsung first developed the 40-inch model in August 2001, the 46-inch panel in October 2002, the 57-inch model in December 2003 and now the first 82-inch panel.
The soon-to-be operational Tangjeong production facility uses glass substrates that measure 1.87m x 2.20m, enabling the production of two 82-inch panels from a single substrate. Previously, technological limitations prevented the development of LCDs this size and, competitive technologies, such as PDP and DLP, were used to produce large-sized panels.
Samsung’s latest large-screen TFT-LCD offers a variety of features. The company applied its patented Super Patterned-ITO Vertical Alignment (S-PVA) technology to achieve extra-wide viewing angles. In addition, the product boasts a low-dispersion colour filter and ultra high aperture ratio achieving a contrast ratio of at least 1200:1 and brightness of 600nit (cd/m2). Response times are at 8ms or faster, providing clear moving picture images. A high-colour-saturation backlight raises colour saturation to 92% to produce a premium quality image.
Sang Soo Kim, senior vice president and head of the LCD Development Centre, said: “Our 82-inch LCD panel proves Samsung Electronics’ technological leadership. It uses our proprietary S-PVA technology, eliminating distortion from all angles and offers a 180-degree viewing angle. With this panel, we have achieved the world’s best performance in terms of contrast ratio, viewing angle and colour saturation.”
Samsung’s new seventh-generation TFT-LCD production line at Tangjeong will be used to produce the company’s full line-up of LCD modules for TV: from 23-inch (24 per substrate), 26-inch (18 per substrate) and 32-inch (12 per substrate) to 40-inch (8 per substrate) and 46-inch (6 per substrate).
Samsung Electronics claim that they are at least one year ahead of the competition in terms of using seventh-generation production technology to make modules of 40 inches, 46 inches and 57 inches. It is therefore in a position to take an early lead in the fast-growing market for large-screen wall-hanging TVs. The development of the 82-inch TFT-LCD marks the launch of Samsung’s and Sony’s joint venture into the S-LCD market. The new line will begin mass production at the end of March.
