Panasonic PT-56LCZ70 56" 16:9 Black LCD Technology 1080p Projection TV

Introducing the world's first consumer television with the innovative LIFI light source. LIFI stands for LIght FIdelity. This is a brand-new way to achieve long light source life, quick start-up time and high color fidelity for projection display. 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.
