The Eastman Kodak Company and Sanyo Electric Co. Ltd. have formed a joint venture for manufacturing organic light-emitting diodes (OLEDs). Unlike a discrete LED which has crystalline origins, an OLED is a film-based emitter of light. An OLED display is self-luminous, so it does not require a backlight, weighs less than half of its LCD counterpart, and uses less power. It is also easily patterned for producing flat panel displays. The new technology has thin layers of individual carbon-based elements that emit light when electric current passes through them. A 2.5-inch (measured diagonally) OEL display has 190,000 pixels. Each element or pixel is independently turned on or off, creating multiple colors and fluid, smooth-edged images on the display. And the OLED display won't fade out when the viewer moves from side to side because the viewing angle is 160 deg. The display is readable in bright sunlight and total darkness. The two companies are beginning with a pilot facility this year and graduating to full production in 2003. The displays are designed for use in telephones, cameras, personal digital assistants, and portable entertainment machines. Visit www.kodak.com/US/en/corp/infoImaging/devices_flatPanel.shtml.
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
