Panasonic Delivers World's First LIFI HDTV

Newest Line of Micro Displays Features Innovative Light Source and Quick Start-Up


SECAUCUS, N.J., Aug. 22 /PRNewswire/ -- Panasonic has started to ship a new line of High Definition LCD Rear Projection Display televisions featuring the revolutionary long-life LIFI(TM), a first-of-its kind light fidelity projection display application that ensures image brightness over an extended period of time as well as greatly reduced start-up time. The Panasonic LIFI High Definition line includes two series - the LCZ and LCX. The LCZ series, available in three large-screen screen sizes, 61-inches, 56-inches and 50- inches, feature 1080p resolution and an elegant glossy black finish with a new floating panel design. The PT-61LCX70 and PT-56LCX70 offer 720p resolution.

"The unique LIFI technology provides the consumer with a viable, affordable option for big screen, 1080p High Definition entertainment," said Dennis Eppel, Vice President of Panasonic Display Company. "The fact that the bulb will virtually never need to be replaced is a great benefit to the consumer and one of the reasons we strongly believe that LIFI will be successful. From our Plasma and LCD TVs to the LIFI HDTVs, we want Panasonic consumers to experience the absolute best in High-Definition home theater. With our breadth of High Definition choices we are confident that Panasonic can provide that experience."

By converting HID (High Intensity Discharge) lamps to LIFI, the models enjoy an especially long life span with incredible brightness. When the electrodes in HID lamps deteriorate and the tungsten evaporates, it causes diminished brightness, as well as damage to the lamp itself. The light source in the Panasonic LIFI HDTV does not use electrodes, resulting in more stable performance and a considerably longer lifespan. Additionally, Panasonic's LIFI technology projects a wide variety and spectrum of light, allowing for the most radiant reds, greens and natural skin tones.

The start-up time for a Panasonic LIFI HDTV is a fraction of the time it takes for a traditional LCD projection set to start up. This is because the light source does not use electrodes and the LIFI bulb is 1/8 the size found in an HID lamp, so the temperature rises more rapidly, enabling faster start- up. The actual time from the moment the set is turned on until there is a picture is now reduced from 60 seconds or more to approximately 15 seconds.

With a longer lifetime, the LIFI HDTV series offers the same performance as an LED model, but at a lower price point. The LIFI lamp generates less scintillation noise than traditional HID lamps, and the invisible speakers marry impeccable design with high-quality sound. Using the device's remote control, users can easily enjoy EZ Sync(TM)-enabled products such as Blu-ray Disc players.

Additional features of the LCX70 Series include:
-- LIFI Light Source

-- New 720p LCD Panel

Thankfully, the days of 5-8,000 hr. lamps @ $300 a shot are over. It will be interesting to see what effect this will have on Sony's sales, but no doubt they will now have a comparable arrangement which has no doubt been sitting in the wings all these yea

I've always wondered how Sharp could use 60,000 hr. lamps On what? Not an arc lamp. That sounds like the backlighting on a LCD flat panel. This article is about LCD projection...

Sorry, I completely overlooked the point that Sharp used backlighting instead of a lamp, but the fact remains that if Sharp chose to go that route, even though it meant no residual returns, then it begs the question why then don't others ?

seems you are missing an engineering thingy here... :wink: Backlighting an LCD panel is a different animal than a lamp in a projector... Think of mini flourescent looking tubes spaced out behind a very large screen, LCD flat panel, versus a single li

I realise that, but the point I am making is that there are many ways to "skin the cat". Which raises the question of why certain manufacturers opted for the approach that brings in future residuals rather than the approach taken by others that don't. Whe

Oh, please spare me the tired and worn "conspiracy theory" accusation, for one, the word "conspiracy" implies more than one involved, and I am talking here specifically of Sony, and it is well to remember that profit is the salient factor in any commercia
