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 displays. 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. The light source in Panasonic LiFi HDTVs offers full spectrum illumination that faithfully reproduces brilliant red, emerald green and natural skin tones. Whether you're watching hidden camera footage of rare Amazon Forest dwellers or taking in the local newscast, the lifelike color is a bright, beautiful enhancement to your HDTV experience.The LiFi lamp is an advancement in technology that offers advantages that you can see and hear - or not, in the case of scintillation noise. HID lamps generate noise, especially at high brightness levels. You won't hear the hum with the LiFi because it operates at lower wavelengths. Plus, because the small LiFi bulb heats up quickly when you power up, the start-up time of the HDTV is as low as 10 seconds. Once your HDTV is ready to watch, there's no flicker, as with some LCD TVs.Everything about the LiFi HDTV is designed to bring you to a new level of viewing pleasure. The amazing colors are boosted by the floating feeling provided by the flat panel design, and the audio is rendered more lifelike by the invisible speakers that help fuse picture and sound.
