Samsung Demos World's First 40-Inch TFT-LCD TV Panel
Samsung Semiconductor, Inc. today announced that it will demonstrate the world's first 40-inch TFT-LCD panel for use in high-performance, wide-screen digital TVs at the Society of Information Display (SID) 2002 Conference, May 21-23 in Boston, Mass. This is the largest TFT-LCD panel ever produced.
Samsung's 40-inch WXGA-resolution TFT-LCD utilizes Samsung's patented Patterned Vertical Alignment (PVA) technology, optimized for digital broadcast reception. PVA technology provides a fast 12ms response time, enabling the display to fully support moving pictures at TV viewing rates and offers a wide, 170-degree conical viewing angle, a high contrast ratio exceeding 600:1, a high screen brightness of 500 nits, and an aspect ratio of 15:9. [an error occurred while processing this directive] The display's 983,040 pixels (1,280 horizontally by 768 vertically) reproduce 16.7 million colors, resulting in a true-color picture with WXGA resolution. Additional features are a low power, 180-watt operation and a 50,000-hour replaceable backlight.
The utilization of PVA technology facilitates the mass production of high-resolution TFT-LCDs in sizes from 30 to 40 inches. Until now, larger-size TFT-LCDs have been technologically difficult to produce.
"This is truly a technology breakthrough for the wide-screen digital TV market," says Dr. Wing Li, chief display scientist, at Samsung Semiconductor, Inc. "Now big-screen, flat-panel TV is a practical reality."
Samsung's 40-inch TFT-LCD display with its low power consumption, high picture quality, and long lifetime is expected to open the door for much broader use of TFT-LCDs on wide-screen TVs.
Samsung's new 40-inch TFT-LCD was first manufactured in August 2001, just ten months after its initial concept. This is testament to Samsung's steadfast commitment to the development of cutting-edge TFT-LCD technology and sophisticated processing of large glass substrates.
In addition to the new 40-inch TFT-LCD display model, Samsung offers an extensive line of TFT-LCDs for TV application, in sizes from 15 to 32 inches. Samsung officials forecast that the availability of these larger TFT-LCDs, especially the 40-inch model, will significantly increase the company's share of the rapidly emerging digital TV market. Now that Samsung has perfected PVA technology to produce a 40-inch display for TV application, the company forecasts that sales of TFT-LCD TV displays larger than 20 inches will rapidly increase.
Samsung is the world's leading volume-supplier of large-size TFT-LCDs, a position the company has maintained since 1997 when it introduced the industry's first 30-inch TFT-LCD TV and the world's first 17-inch display for desktop PC use. Display Search, an industry analyst firm, estimates the world's TFT-LCD TV market at 2.52 million units this year and expects it to grow to 9.8 million units by 2005.
Samsung's new 40-inch TFT LCD for TV application, and a full range of Samsung TFT-LCD displays in all sizes, are on display at the Samsung Semiconductor, Inc. booth number 2317 / 2418 at the Society for Information Display International Symposium, Seminar & Exhibition (SID), May 21-23, 2002, at the Hynes Convention Center, Boston, Mass.

About Samsung's Patterned Vertical Alignment (PVA) Technology
In this display panel technology, the liquid crystal molecules are originally aligned at 90 degrees vertically to the electrodes. The passage of an electric field deflects the liquid crystal molecules off-vertical, producing the required image. The deflection required for this is much less than that required for traditional LCDs. This results in a display with a faster response time that allows it to run at video-framing rates and, concurrently, provides a wider viewing angle and a higher contrast ratio.
