05/19/2005 - Samsung Electronics, the leader in TFT-LCD technology, today announced that it has successfully developed the world's first single-sheet, 40-inch active matrix (AM) OLED ( organic light-emitting diode ) for emissive flat panel TV applications. The high-definition-compatible OLED prototype has a wide screen pixel format of 1280x800 (WXGA) driven by an amorphous silicon (a-Si) AM backplane to permit faster video response times with low power consumption. Samsung's 40-inch OLED panel will be demonstrated for the first time at the world's largest display industry event, Society for Information Display (SID) 2005 International Symposium, Seminar and Exhibition in Boston, May 24– 27.
Manufactured on Samsung's fourth generation (4G) production line with a mother-glass size of 730mm x 920mm, the new OLED prototype combines all of the traditional features of emissive OLED technology, including wide viewing angle, thin package size, no color filter and no backlight, with the enormous production infrastructure advantages of standard a-Si techniques. To date, AM OLED prototypes have used costly polysilicon approaches, which have limited production sizes.
Shattering traditional AM OLED size limitations, the new prototype offers a maximum screen brightness of 600 nits; a black-and-white contrast ratio of 5,000:1; and, a color gamut of 80 percent. Motion pictures with ultra-high quality images can be impeccably reproduced by skillfully employing OLED's rapid video response capabilities for image processing of HD-class resolution. The ultra-thin shape of the panels will allow future TV set designers to create televisions with a total thickness of only 3cm or less.
After launching its OLED development initiative in 2001 to secure leadership in next-generation display technologies, Samsung developed a 14.1” WXGA (1280x768) OLED panel in 2004, followed by the world's first 21” HD-class (1920x1080) OLED panel in January, 2005. This ambitious pace of innovation accelerated development of today's unusually large 40-inch OLED prototype, paving the way for large-size OLED TVs.
01/04/2005 - Samsung Electronics, the leader in TFT-LCD technology, announced today that it developed the largest single-panel active matrix-based (AM) Organic Light-Emitting Diode (OLED) display. At 21-inches, this OLED features the highest resolution at 6.22 million pixels (WUXGA: wide ultra-extended graphics array). In addition, the company adopted AM-based technology for its low power consumption and high-resolution qualities. Samsung's new OLED offers brightness of 400 nit, contrast ratio of 5000:1, color gamut of 75 percent and fast response times, making the product ideal for viewing HD-resolution video images.
03/17/2005 - Demonstrating its technology leadership in the display market, ViewSonic® Corp., a worldwide leader in visual display products, today announced the world’s fastest LCD monitors. Featuring ultra-fast 4 millisecond (ms) average video response time across the entire color scale, the 19-inch VX924 and 17-inch VX724 deliver fluid, full-motion images and optimized video performance for a variety of applications. With typical “fast-response” displays on the market today having an average gray-to-gray (or intermediate level) response time of 30 to 35ms, ViewSonic’s Xtreme LCD lineup provides response time performance up to 8 times faster. They are ideal for extreme gaming, viewing DVDs, watching television, and even traditional computer usage—such as rapidly scrolling content within a Web site or a document. The VX924 and VX724 are the first desktop displays to combine ViewSonic’s proprietary Dynamic Structure™ and Amplified Impulse™ video response acceleration technologies to support rates of up to 250 frames per second across the entire color scale. This advancement produces superior front-of-screen performance for motion video, since the majority of video transitions on games and digital entertainment occur within these intermediate ranges. The displays will be available in the second quarter of 2005 through traditional ViewSonic resellers, distributors and mail order.
01/06/2005 - ViewSonic® Corp., a worldwide leader in visual display products, today brings more value to customers by significantly accelerating performance with industry leading response times, while lowering prices on three of its popular ThinEdge™ LCD monitors. To achieve ClearMotiv™ response times as low as 8ms, the company has developed and added technologies that enhance the speeds of its 19-inch VP191b and 17-inch VP171b and VP171s, making them well suited for motion-intensive applications such as gaming, digital video and web editing. The improved VP191b will be available in February through authorized ViewSonic resellers, distributors and mail order outlets for an estimated street price (ESP) of $549. Available now, the silver VP171s can be purchased at various retail outlets with an ESP of $389, while the black VP171b is sold through authorized ViewSonic resellers, distributors and mail order outlets.
Motorola Labs Debuts First Ever Nano Emissive Flat Screen Display Prototype
05/09/2005 - SCHAUMBURG, Ill. – Motorola Labs, the applied research arm of Motorola, Inc., today unveiled a working 5-inch color video display prototype based on proprietary Carbon Nanotube (CNT) technology – a breakthrough technique that could create large, flat panel displays with superior quality, longer lifetimes and lower costs than current offerings. Optimized for a large screen High Definition Television (HDTV) that is less than 1-inch thick, this first-of-its kind NED 5-inch prototype harnesses the power of CNTs to fundamentally change the design and fabrication of flat panel displays. The development of such a flat panel display is possible due to Motorola Labs Nano Emissive Display (NED) technology, a scalable method of growing CNTs directly on glass to enable an energy efficient design that excels at emitting electrons. Through this cost-effective process and design, Motorola showcases the potential to create longer-lasting NED flat panel displays with high brightness, excellent uniformity and color purity. Motorola’s proprietary CNT growth process provides excellent precision in designing and manipulating a material at its molecular level – enhancing specific characteristics – and, in the case of flat panel displays, producing high-definition images. The electron emission performance demonstrated by the Motorola technology exceeds that achieved to date with the application of the CNT to the cathode via an organic paste, the process used by other companies.
