LG Semicon Develops 18.1 Inch SXGA TFT-LCD.LAS VEGAS--(BUSINESS WIRE)--November 15, 1998 - Spotlights Industry's First Feature Set of Ultra Wide Viewing Angle and High Brightness LG Semicon announces the development of its 18.1 inch thin-film-transistor liquid crystal display liquid crystal display (LCD) Optoelectronic device used in displays for watches, calculators, notebook computers, and other electronic devices. Current passed through specific portions of the liquid crystal solution causes the crystals to align, blocking the passage of light. (TFT-LCD TFT-LCD Thin Film Transistor - Liquid Crystal Display ), LM181E2 following the success of LG's 15.1 inch LCD. With the assistance of In Plane Switching (IPS (1) (Inches Per Second) The measurement of the speed of tape passing by a read/write head or paper passing through a pen plotter. (2) (IPS) (Intrusion Prevention S ) technology, this model offers a breakthrough feature combination of the world's first wide viewing angle of 160(Degree) (top to bottom) and 160(Degree) (left to right) with an exceptional high brightness of 200 nit. "Historically a major impediment of LCD technology has been the poor viewing angles by the displays. When users attempted to view the screen from the side or from the top or bottom, they would see color changes and image distortions," said Hyung Yoon, Vice President, LG Semicon. "LG Semicon masters In Plane Switching (IPS) technology and overcomes this limited viewing angle problem with the new 18.1" TFT LCD (Thin Film Transistor LCD) See LCD. featuring a breakthrough angle of 160(Degree)/160(Degree)." The new 18.1 inch TFT-LCD is just 2.25 cm thick and weighs only 3 kg. 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 See CRT. (hardware) cathode ray tube - (CRT) An electrical device for displaying images by exciting phosphor dots with a scanned electron beam. CRTs are found in computer VDUs and monitors, televisions and oscilloscopes. and do not emit harmful electromagnetic waves. In addition, TFT-LCDs also use less electricity than CRTs. The LM181E2 operates on 20 watts of power, 20% of the electricity needed in a traditional CRT (1) (C RunTime) See runtime library. (2) (Cathode Ray Tube) A vacuum tube used as a display screen in a computer monitor or TV. The viewing end of the tube is coated with phosphors, which emit light when struck by electrons. of the same size. The panel offers SXGA (Super XGA) A screen resolution of 1280x1024 pixels. SXGA is commonly used on standard monitors, but provides a 1.25:1 aspect ratio, compared to the more common 1.33:1 (4:3) ratio. SXGA+ has a 1400x1050 resolution, which is an exact 1.33:1 ratio. See PC display modes. (1280 x 1024) picture quality, which amounts to 3.9 million pixels. Response time has been brought down to 50 milliseconds for excellent display quality for the high-end monitor market. The LM181E2 features a high 36% aperture ratio (the amount of light emitted from each pixel) and a uniquely designed 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. to achieve 46% color saturation. In addition, the new TFT-LCD can display 16.7 million colors, providing pictures that are very close to real life. Target markets for the 18.1 inch TFT-LCD are workstations, CAD/CAM CAD/CAM in full computer-aided design/computer-aided manufacturing. Integration of design and manufacturing into a system under direct control of digital computers. monitors, dealing room monitors in financial companies and monitors in medical centers. This unit will be commercially available in December 1998. Initial output is expected to be 12,000 units per month. -0- Established in 1958 as Korea's pioneer consumer electronics company, LG Electronics is a global manufacturer of electric and electronics products with $9.7 billion in worldwide sales.
