Samsung Shows New LCD Display Technology
May 23, 2005
Seoul, Korea - Samsung Electronics, showed new display panel technology at the Society for Information Display (SID) 2005 conference in Boston. The company said their 82-inch LCD panel display is the largest LCD panel in the industry.
They also demonstrated a 40-inch amorphous, silicon-based, active matrix OLED (organic light emitting diode) display designed to permit the design of large ultra-thin TVs only 3 cm thick.
Other products shown include:
-- an LED Back Light LCD TV with 107 percent NTSC color reproduction, and
-- three-wave light emitting diode (LED) backlighting technology for mobile displays with color tones enhanced to 86 percent NTSC.
The 40-inch amorphous silicon OLED prototype, unveiled at SID is the world's largest single-sheet glass plate OLED, according to the company, and demonstrates that Samsung Electronics' implementation of OLED is unique and scalable to large-screen TV sizes. They said it employs WXGA (1280 x 800) HD-class resolution and screen brightness of up to 600 nits, as well as a black-and-white contrast ratio (shade ratio) of at least 5,000:1 and a color reproduction scale of 80 percent or higher. The ultra-slim panel is designed to enable large-sized OLED TVs with a thickness of only 3 cm or less.
Samsung says their 82-inch LCD TV panel is the largest LCD panel in the world and is being exhibited for the first time in the Americas at the SID conference. The 82-inch LCD prototype was produced on the world's largest TFT-LCD (1,870 mm x 2,200 mm) production line, located in Tangjeong, Korea. Benefiting from 7G (Seventh Generation) technology, Samsung's 82-inch LCD prototype is equipped with proprietary extended viewing angle technology. The company says the LCD has an unsurpassed vertical and horizontal viewing angle of 180 degrees, 92 percent NTSC color reproduction and a screen quality response speed of 8 ms or less. In addition to the 40- and 46-inch LCD TV panels currently in mass production, Samsung believes that the 82-inch LCD TV panel, along with a 57-inch LCD panel, will impact the growth of the large LCD TV market significantly.
A 2.22-inch RGB (Red, Green, Blue) backlight LCD also is featured at the Samsung Electronics' exhibition area. The 2.22-inch backlight LCD uses a three-wave LED light source of red, green and blue instead of a conventional two-wave light (blue and yellow) LED, allowing it to provide greater color reproduction for mobile LCDs. The three-wave LED light source is designed to allow the 2.22-inch backlight to offer enhanced color tones, improving color reproduction from today's 60 percent to 86 percent, relative to NTSC standards.
In addition, Samsung Electronics is displaying an ultra-slim 46-inch LED BLU (Back Light Unit) at SID that employs "Xmitter", the company's proprietary optical technology. "Xmitter" technology has an optical structure that the manufacturer says enhances light usage efficiency by more than 40 percent, relative to today's widely used side scan method. According to Samsung, 46-inch LED BLU consumes 40 percent less power, compared to existing LED products. The company adds that it not only displays outstanding color reproduction at 107 percent and brightness of 500 nits(2), but is being positioned as the next-generation light source for meeting environmental regulations involving the use of mercury and lead, which begin to go into effect in Europe in 2006.
Other Samsung panel products at SID include a research prototype of the world's largest transmissive 5-inch plastic LCD (a-Si-based) which can be featured in wearable, fashion displays, and a semi-transmissive 2.22-inch mHD (mobile High Definition) LCD capable of ultra high-resolution in mobile and other devices.
On Tuesday, May 24th, President of Samsung Electronics LCD Business, Sang Wan Lee, will deliver the opening keynote speech examining the growth potential of LCD TVs, and forecast the future for flat displays in a presentation entitled "LCD Revolution -- The Third Wave."
