OSRAM Opto Semiconductors Redefines RPTV Applications With OSTAR LED Solutions.Newest OSTAR OSTAR Ontario Small Town and Rural Program OSTAR Observer Singlehanded Trans-Atlantic Race (sponsored by UK newspaper Observer) OSTAR Order and Shipping Time Analysis Report Light Source Provides Improved Projection Luminance The amount of brightness, measured in lumens, that is given off by a pixel or area on a screen. For example, dark red and bright red would have the same chrominance, but a different luminance. , Enhanced Features and Longer Lifetimes SAN JOSE San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif. -- OSRAM Opto Semiconductors Inc., a leader in light-emitting diode (LED) technology, today announced its newest OSTAR[R] Projection RPTV See rear-projection TV. product specifically designed for rear-projection television (RPTV) applications. To meet the continually increasing demand for brighter, sharper, more vivid displays, RPTV manufacturers are turning to LED technology to improve the performance of HDTV (High Definition TV) A set of digital television (DTV) standards that offer the highest resolution and sharpest picture. Although some HDTV sets are available in standard (rather square) screen sizes, the overwhelming majority of sets are wide screen, which eliminates . "OSRAM has added an important product to complement our comprehensive OSTAR family portfolio, supporting a rapidly growing and exciting industry," Ellen Sizemore, director, LED/IR Marketing, OSRAM Opto Semiconductors Inc., said. "Our OSTAR Projection RPTV product is mercury free and delivers vivid color, high brightness and long life, enhancing high definition television technology for the future." OSRAM's underlying proprietary ThinFilm (red color) and ThinGaN (green and blue) technologies are used to ensure high efficiency and outstanding luminance. These ThinFilm OSTAR LEDs are "surface emitters" which produce very high luminance from a small emission area without the need for reflectors. In combination with an appropriate imager, system output of 300 lumens (lm) can be achieved for RPTV systems. Conventional RPTV systems suffer from short lifetimes due to commonly used discharge lamps. OSTAR's average lifespan is between 20,000 and 50,000 hours, meaning fewer lamp replacements and lower maintenance costs than conventional light sources, making this product perfect for rear-projection televisions where re-lamping is often difficult. Discharge lamps also need up to five minutes to warm up to full brightness. For RPTV, one red, one blue and one green OSTAR are used; each supplied with a special optic. Typical outputs are 750 lumens for red, 1250 for green and 180 for blue. OSTAR Projection RPTV is suitable for all RPTV technologies, whether they are based on DMD (1) (Digital Micromirror Device) See DLP. (2) (Digital Multi-layer Disk) See high-def DVD formats. (Digital Micro Mirror Device), LCoS (Liquid Crystal on Silicon Liquid crystal on silicon (LCOS or LCoS) is a "micro-projection" or "micro-display" technology typically applied in projection televisions. It is a reflective technology similar to DLP projectors; however, it uses liquid crystals instead of individual mirrors. ) or LCD (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. ). An RPTV with a screen diagonal of 56 inches equipped with these LEDs can achieve a luminance of up to 500 cd/m. This ensures that the picture has good contrast, vibrant colors and razor-sharp definition. OSTAR Projection RPTV enables manufacturers to produce large-screen RPTVs with outstanding features such as instant on, elimination of the color wheel resulting in higher mechanical reliability and pictures with wider color range, more vivid colors "Vivid Colors" is the second single of Japanese band L'Arc-en-Ciel.
