Samsung Develops World's Largest -- 82'' -- Full HDTV TFT-LCD.SEOUL, South Korea -- --The world's largest (82-inch) TFT-LCD TFT-LCD Thin Film Transistor - Liquid Crystal Display developed at Samsung's new 7G line. --Viewing angle of 180 degrees achieved by applying Samsung's proprietary S-PVA S-PVA Super Patterned Vertical Alignment (Sony LCD technology) technology. --12.44 million thin-film transistors used to achieve full HD image quality of 6.22 million pixels See pixel. . Samsung Electronics Samsung Electronics (SEC, Hangul:삼성전자; KSE: 005930, KSE: 005935, LSE: SMSN, LSE: SMSD) is a South Korean multinational corporation and the world's largest and leading electronics and information technology company. , the leading provider of TFT-LCD display panels, announced that it has developed the world's largest 82-inch TFT-LCD. This full HD image quality TFT-LCD panel was developed at the company's new production complex in Tangjeong, Korea. The soon-to-be operational 7th-generation production facility uses glass substrates that measure 1.87m x 2.20m. Samsung has made a series of breakthroughs in TFT-LCD technology ahead of the competition over the years. The company developed the first 40-inch model in August 2001, the first 46-inch panel in October 2002, the first 57-inch model in December 2003 and now the first 82-inch panel. At its 7th-generation Line 7-1, Samsung can produce two 82-inch panels from a single substrate. Previously, technological limitations prevented the development of LCDs of this size and competitive technologies, such as PDP (1) (Plasma Display Panel) See plasma display. (2) (Policy Decision Point) See COPS and XACML. (3) (Programmed Data P (plasma display panel See plasma display. ) and DLP (Digital Light Processing) A data projection technology from TI that produces clear, readable images on screens in lit rooms. DLP is used in all types of projection devices, from data projectors that weigh only a few pounds to large rear-projection TVs to electronic (digital light processing) technologies, were used to produce such 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 color filter Color filter An optical element that partially absorbs incident radiation, often called an absorption filter. The absorption is selective with respect to wavelength, or color, limiting the colors that are transmitted by limiting those that are absorbed. and ultra high aperture An orifice. It often refers to an opening in which light is allowed to pass in optical systems such as cameras and lasers. See f-stop and numerical aperture. ratio, achieving a contrast ratio of at least 1200:1 and brightness of 600nit (cd/m(2)). Response times are at 8ms or faster, providing clear moving picture images.

Sang Soo Kim, Senior Vice President and Head of the LCD Development Center, states, "Our 82-inch LCD panel Also called a "projection panel," it is a data projector that accepts computer output and displays it on a see-through liquid crystal screen that is placed on top of an overhead projector. See data projector. 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 color saturation." Samsung is set to begin operations at the world's first 7th-generation TFT-LCD production line at Tangjeong, Korea. This facility can 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 is at least one year ahead of the competition in terms of using 7th-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 highlights the smooth launch of Samsung's and Sony's joint venture in S-LCD. The 7th-generation line will begin mass production at the end of March. Samsung Electronics will unveil its 82-inch TFT-LCD at CeBIT 2005, which opens in Hannover, Germany on March 10.

Terminology PVA PVA polyvinyl alcohol. Technology Patterned-ITO Vertical Alignment is a proprietary Samsung technology for achieving a wide viewing-angle. The liquid crystal molecules are originally aligned at 90 degrees vertically to the electrodes Electrodes Tiny wires in adhesive pads that are applied to the body for ECG measurement. Mentioned in: Electrocardiography . The passage of an electric field deflects the liquid crystal molecules off-vertical, producing the required image. Similar to the multi-domain vertical alignment (VA), the liquid crystals are controlled by separating unit pixels into four domains. S-PVA Technology Samsung's patented Super PVA is an upgraded PVA liquid crystal cell technology. The cell architecture accommodates eight, rather than the conventional four crystals, so that the liquid crystal molecules can be controlled in eight different directions and angles. This capability greatly enhances the side viewing-angle of the LCD screen. Color Saturation This is a measurement of color not of the white race; - commonly meaning, esp. in the United States, of negro blood, pure or mixed. See also: Color purity and is compared against the NTSC (National TV Standards Committee) The committee that developed the television standards for the U.S, which are also used in Canada, Japan, South Korea and several Central and South American countries. Both the committee and the standard are called "NTSC. (National Television Standard Committee) standard of 100. Commercial CRT (1) (C RunTime) See runtime library.
