Light guide film technology for backlight solutions

Avago Technologies has launched an innovative ultra-thin, high brightness, light guide film (LGF) technology for backlighting mobile applications, such as cell phones, handheld games and GPS applications, that helps designers reduce the number of LEDs needed to illuminate backlit keypad applications without compromising brightness and light uniformity.

The patented Graphic Fusion Multimode Exchangeable (G2MEX) technology solves the issues of complexity and congested icons on keypads and keyboards. The solution allows key characters to be overlapped and selectively illuminated. Moreover, the illumination areas are transparent to each other – an area will be invisible when it is not backlit. G2MEX is an ideal choice for phones with MP3 players or any multi-function handset, especially those with capacitive sensing keypads.

Avago’s LGF technology just requires two side-firing LEDs to backlight display icons uniformly, compared to conventional solutions, which use six or more top-firing LEDs. This results in lesser power consumption, smaller board area, and longer battery life.
