SAMSUNG Electronics Develops 30 Inch Single Glass UXGA TFT-LCD

SEOUL, Korea - October 15, 1997 - Samsung Electronics Co., Ltd. announced on October 15, 1997 that it had completed development of the world's first 30" thin-film-transistor liquid crystal display (TFT-LCD) for use in next-generation, high-definition multimedia displays and large screen wall-hanging TVs.

Samsung developed a 22" model in 1995 and then began work on this next-generation version, spending about W10 billion in R&D. The new TFT-LCD provides the same effective screen as a conventional 33" Cathode Ray Tube (CRT) TV and provides a clearer picture than the Plasma Display Panel (PDP) of High Definition TV (HDTV). In addition, with the technology used to develop the 30" UXGA TFT-LCD, the development of 40" models can be at hand.

Development Significance
The greatest technological barrier to developing next-generation large screen LCDs has been in the use of a single glass panel rather than multiple panels. Samsung has managed to develop a 30" single-panel model. As a result, the company has mastered core technology for super-high-definition displays as well as for injecting liquid crystal into screens of 30 inches or larger. Samsung has already received 18 patents related to its new TFT-LCD and is currently applying for still more patents.
Now Samsung has the technology to add extra-wide-screen TFT-LCDs to the product lineup being mass produced at the company's plants in Kiheung and Chonan (will open in the first half of 1998).

Product Features
The new 30" TFT-LCD developed by Samsung has an effective screen size of a regular 33" CRT TV, but the new Samsung product is just 4.5cm thick and weighs only 7.5kg. It operates on 45 watts of power, one-fifth the electricity needed in a conventional TV of the same size.
The product offers UXGA (Ultra eXtended Graphics Array) picture quality, which amounts to 5.76 million pixels (1,600 x 1,200 x Retd Green Blue pixels). Response time has been brought down to 40 milliseconds or lower for excellent motion picture reproduction and clarity.
Samsung used its patented technology to produce an industry high 70 aperture ratio (the amount of light emitted from each pixel) and added its uniquely designed color filter to achieve 65 color saturation, another industry high. The new TFT-LCD can display 16.7 million colors, providing pictures that are very close to real life.
Viewing angle has been a constant problem with LCD screens, but Samsung's new product has an improved viewing angle of 80 degrees top to bottom and 120 degrees left to right. Up to now, the Samsung TFT-LCD has been designed for use as either a monitor or TV screen. But, this new product can handle signals from computers, frequencies used for public TV, as well as, signals from VCRs.
TFT-LCDs not only provide the advantages of being thin, light and having high definition, but they also are easier on the eyes than cathode ray tubes and do not emit harmful electromagnetic waves. TFT-LCDs also use less electricity than CRTs. With this development, Samsung has made the first steps to bringing the advantages of TFT-LCDs available to large screen wall-hanging TVs and multimedia products.

Samsung Electronics Co., Ltd., a US$19 billion flagship company of Korean-based the Samsung Group, is a world leader in electronics, with operations in more than 60 countries.
