SAMSUNG Electronics Develops the World's First 40-inch TFT-LCD

SEOUL, Korea August 22, 2001 Back in 1997, Samsung Electronics was the world's first company to come out with a 30-inch thin-film-transistor liquid crystal display (TFT-LCD).

Now, the company has proven its industry-leading technology once again by being the first to complete development of a 40-inch (980.9mm x 629.6mm) TFT-LCD, ushering in the era of wide-screen TFT-LCD TVs.

The new product has approximately 980,000 pixels (1,280 horizontally by 768 vertically) to provide a wide screen with XGA (eXtended Graphics Array) definition. The aspect ratio is 15:9 and the screen measures 40 inches diagonally. It is targeted for use in high-performance, wide-screen digital TVs.

TFT-LCD production processes become increasingly difficult, as the screen size grows larger. Until now, 30 inches was considered the technological limit for this type of display, while many companies have been researching ways to come up with wider screen products. Samsung's achievement is considered a technology breakthrough for TFT-LCDs.

Samsung has also greatly improved the viewing angle, brightness and response time--aspects that have been pointed to as weaknesses in the TFT-LCD. Importantly, the company has applied its exclusive Patterned Vertical Alignment (PVA) technology to give a viewing angle of 170 degrees. Response time has been shortened to just 12 milliseconds, fast enough to fully support moving pictures. Thus, the new display can easily be used on a TV.

The full-color display function reproduces 16.7 million color tones, while the black-and-white contrast ratio is 600:1. Brightness is 500 candelas. These specifications make it well suited for digital broadcasting.

Samsung's new 40-inch TFT-LCD has more than twice the pixels of a 42-inch VGA (Video Graphics Array) plasma display panel, giving it much better picture clarity. At the same time, the TFT-LCD operates on 180 watts, about half the power required by a PDP of the same size. The TFT-LCD is guaranteed to last around 50,000 hours, three times the lifetime of a PDP. After this period, one simply has to replace the backlight to continue using the product.

Today, TFT-LCDs and PDPs are competing for supremacy in the flat panel display TV market.

Samsung's new TFT-LCD, with far superior functions than its PDP counterparts, is expected to open the door for much broader use of TFT-LCDs on wide-screen TVs.

Samsung began working on a 40-inch model last year, and achieved its technology breakthrough after just ten months, testimony to the company's world-leading TFT-LCD technology and sophisticated processing of large substrates.

Samsung Electronics has maintained the top share of the world market for TFT-LCDs of 10 inches and larger for the past three years. In addition to the new 40-inch version, the company plans to offer a variety of TFT-LCDs for TVs, including 15, 17 and 20 inch models, bolstering this business segment significantly.

Samsung will exhibit the new 40-inch TFT-LCD, a 17-inch model for LCD TV and new models for desktop monitors and notebook PCs at the International Meeting on Information Displays 2001, in Daegu, Korea from August 28th to 31st.

Display Search, an industry analyst, estimates that the world LCD TV market will total 2.52 million units this year and grow at least 40% a year to reach 9.8 million units by 2005.
