Introducing the world's first consumer television with the innovative LIFI™ light source. LIFI stands for LIght FIdelity. Unlike conventional LCD projection TVs, the LIFI light source lasts so long it might never need to be changed. The High Intensity Discharge (HID) lamps used in conventional LCD projection TVs contain electrodes that deteriorate, causing diminished brightness and possible damage to the lamp itself. LIFI does not utilize electrodes, which helps achieve more stable performance and a long lifespan.
