People always ask what is better Plasma or LCD TV's?

Technology is changing at a rapid pace and Video Electronics is no exception. When asked were I think the technology is heading and which format of Flat Panel TV is the public likey to embrace Plasma or LCD, I have to say LCD at the moment as Plasma Manufacturers are making moves to change their focus from Plasma to LCD. An emerging technology to look out for in the near future is OLED. Similar to LCD yet cheaper to build.

LCD Pros:
  • Higher Native Resolutions
  • Extremely Detailed Picture
  • Extremely Thin (less then 2.25")
  • Brighter then Most Plasma's
  • Backlight can replaced once it burns out
  • Light Weight
  • True measured contrast ratio surpasses plasma
  • Can't Burn Images
  • Extremely Resistant to Shock
  • Lower Power Consumption
  • No Glare in Direct Sunlight
  • True Black Levels
  • Sharper, Defined Picture
  • Life Span (60,000 + Hours) Replaceable Bulbs
  • Pixels much Smaller Producing a much
  • True Color Reproduction
  • Faster Response Times
LCD Cons:
  • Some What Expensive
  • Largest Screen Available 45"
  • Ghosting affect with fast moving scenes such as action movies and Sporting events.

Will leaving your LCD TV on cause the image to degrade?

A: No. Unlike plasma and CRT TV’s, the LCD TV does not exhibit aging over time. The brightness of the image remains the same.

Do LCD’s have a burn in problem?

No. Unlike CRT and plasma TVs, liquid crystal displays do not use phosphor and thus have no problems with a still image becoming permanently stored on the screen.

Plasma Pros:

  • Available size as large as 70"
  • Lower Prices
  • Bigger sizes
Plasma Cons:

  • Life Expectancy Shorter then LCD
  • Very Few Produce True Blacks
  • A Still Image can Burn on Screen
  • Color Accuracy
  • Most screens look pixilated
  • Extremely Fragile
  • Artifact shows up on weaker signals
  • Slower Response rate equals Artifact
Other emerging technologies to keep an eye on in the near future!
SED is one of several emerging display technologies that, according to their respective backers, do a better job than either LCD or PDP. One such competitor, OLED (organic light emitting diode), is already used commercially for small screens in products such as cell phones but its development has yet to reach the stage where it can be used for televisions. Sony and others have been working for several years on another technology called FED (Field Emission Display) but that too has yet to reach commercialization.
