How long would LCD HDTV's last in the market?

Q. I have bought an LCD HDTV last year and I'm getting worried if my TV's going to be "phased-out" since there has been many new releases of LED TV's and 3DTV's.

The LCD TV I bought was not exactly a new model, it was a bit old, (720p only, but not second-hand). I really hope that my purchase wasn't a waste, and that I should have bought a newer model instead...

A. SLEEPS WELL !
new models , new technology keeps coming out.....every month.. NO END.
if you worries about , don't buy any electronics items.
there is a LIFE TIME for LCD TV. usually about 60,000 hours. an QUALITY BRAND able to use for about 6 to 8 + years switch on 10 hours a day .
if you buy an LED TV . you will ask another same question as OLED TV should be in the market soon ! OR , all LED TV going to be " QUATTRON " technology as Sharp is the only maker for that ( releases 3 months ago ) .
if you buy an 3D TV, you worries about NEXT GENERATION NEW 3D releases in next 3 years.
there is NO NEW MODELS for TV. NEW MODELS is AS THIS MOMENT !!


What are the differences between LCD HDTVs and Plasma HDTVs?
Q. What are their Pros and Cons?

A. LCD HDTVs:

LCD uses little pixels which contain liquid crystals inside of them. These liquid crystals alternate to block out certain spectrums of light, so that the viewer only sees the colour allowed to pass through the pixel. When a million pixels (720p TV) or 2 million pixels (1080p TV) are put together side-by-side, the viewer sees one complete picture.

Pros:
- Longer life span (theoretically)
- Great for brightly lit rooms
- Is now available at bigger sizes like 65"
- No burn-in
- Cheaper to repair
- Uses less electricity

Cons:
- Prone to dead pixels
- Visible artifacts due to slow refresh rates (generally 60Hz)
- Harder to see in brightly lit rooms
- Plastic Screen


Plasma HDTVs:

Plasma HDTVs uses pixels that contain gases like Neon or Argon. When an electric current comes into contact with these gases, the gases heat up and turn into the plasma (thus the name), and because they are so hot, they glow. The colour they emit varies according to the electric current. Because the gases can change colour almost instantly (unlike the LCD's liquid crystals which need to alternate), they have a really high refresh rate.

Pros:
- Fantastic for dark rooms
- Glass Screen
- Very accurate colours
- Deeper blacks
- Comes in very big sizes
- Barely any artifacts due to high refresh rate

Cons:
- Uses more electricity (it'll end up costing no more than 5 cents a month)
- Prone to burn-in (if you leave the sae image on your screen for a long time)
- Slowly dims until the gases completely lose their luminosity
- Very expensive to repair
- LCD is slowly beginning to dominate HDTV market


Hope I helped!
