Lightguide Film Technology

Avago Technologies has announced an ultrathin high-brightness lightguide film technology for backlighting cell phones, handheld games and global positioning systems. It enables designers to reduce the number of LEDs needed to illuminate backlit keypads. The graphic fusion multimode exchangeable (G2MEX) technology relieves the complexity and congested icons on keypads and keyboards. Key characters can be overlapped and selectively illuminated, and the illumination areas are transparent to each other. With this technology, only two side-firing LEDs are needed to backlight display icons uniformly.
