Nichia Increases Brightness of Surface-Mount White LEDs by Fifty Percent
TOKYO, Feb. 7 /PRNewswire/ -- Nichia Corporation announced today the development of surface-mount white LEDs achieving luminous intensity fifty percent higher than current parts. The increased brightness results from a more efficient conversion of electricity to emitted white light, making the part ideal for backlighting of full-color LCD screens in battery powered mobile devices.
Full-color LCD screens, which require a white light source, are becoming more common in a variety of battery powered mobile devices. The most common mobile devices with full color displays are personal digital assistants, handheld video cameras, and digital still cameras. Cellular telephones with full-color LCD screens are also becoming commonplace, particularly in Japan. As a backlight source, white LEDs offer the advantages of compact size, durability, low power consumption, and long lifetime.
``Color displays have always been a big improvement over black and white,'' said Noboru Tazaki, Managing Director and General Manager of Nichia's Optoelectronics Products Division. ``Because they emit more light from less battery power, our new white LEDs make full-color LCD screens practical for a wider variety of mobile devices.''
First samples for the new white LED will be available for Nichia's NSCW215 series, a side view surface-mount LED. The improved NSCW215 emits 600 mcd of light and is only 1.0 millimeter in height. An even thinner side view surface-mount LED, with a height of a mere 0.8 millimeters and a full 600 mcd, will also be available. With no increase in power consumption, the higher brightness and lower profile of both parts make them ideal for backlighting color LCD screens in mobile devices. Engineering samples will be available in this quarter; volume production is targeted for Q2 of calendar 2002... |
