Plasma and LCD TV Advantages and Disadvantages

Plasma and LCD TV Advantages and Disadvantages

Plasma is one of the contenders in the flat-panel market. The other flat-panel contender, LCD TV.

Plasma Advantages and disadvantages
  • Reproduction of colors through plasma pixels is excellent.
  • Plasma screens have a high contrast ratio compared with LCD screens (the other major flat-panel technology), which results in bright whites and true blacks.
  • A wide viewing angle, which means that you can easily view the television even if you are not sitting directly in front of it.
  • A common complaint is that plasmas are susceptible to screen burn-in. This means that images often displayed on the screen leave a permanent impression on the screen.
  • This not such a big problem with newer screens only with older sets.
  • Because the gases used in plasma televisions fade they have a relatively short lifespan compared to other types of televisions (20,000 - 30,000 hours of constant use). The gases cannot be replaced.
  • Plasma screens are much heavier than LCD screens. You may need extra supports when hanging.

LCD TV Advantages and disadvantages

  • LCD TVs have a lifespan of 50,000 to 75,000 hours - that's more than 5 years of 24-hour-a-day operation. And when the bulb wears out, it can simply be replaced.
  • Compared to plasma, LCD TVs are slimmer and lighter. And use very little electricity, which is good for the environment.
  • Contrast is a weakness for LCD screens.
    You may need to buy components such as speakers and a television tuner separately.
