I have heard people talk about the "burn-in" effect. What is that?


When people mention the "burn-in" effects they are talking about plasma displays. In plasma displays static images will begin to "burn-in," or permanently etch the color being displayed into the glass display element. However, with recent plasma technology, this has become less of a problem. Now it takes much longer for an image to "burn-in" compared to before.

Which display has a higher resolution level? LCD or plasma display?


First, let me explain what "resolution" refers to. Resolution refers to the number of pixels a television is capable of displaying. A higher resolution usually corresponds to a sharper image. Generally, LCD HDTV will have a higher resolution compared to a similar-sized plasma display. However, along with a higher resolution, the price will increase also.
I have been asked many times, what's the difference between an LCD display and Plasma display? Well, here you have it. Altough this doesn't cover every difference, it hits the main ones.

How long does an LCD display last? How about a plasma display?


LCD displays have a usual lifespan of about 60,000 hours, although some manufactures claim that they can last up to 80,000 hours. Plasma displays typically last slightly shorter than LCD displays of the same size.

As far as contrast, which is better? LCD or Plasma display?


First, let me explain what "contrast" refers to. Contrast is the brightness of a display at full white over
the brightness of a display at full black. Plasma displays typically have a better contrast ratio. It is not uncommon to see a plasma display with a contrast ratio of 3000:1. An LCD display will usually have a contrast ratio of up to 1000:1. Recently, some LCD displays have surpassed this 1000:1 plateau and are starting to get closer to plasma’s contrast levels.

When it comes to viewing angle, which is better? LCD or plasma display?


Plasma displays have the advantage when it comes to viewing angles. Typically, plasma displays have viewing angles around 160°. LCD displays generally have viewing angles between 120" and 130".
