LCD Vs Plasma

By: Sarah Jacobson

When you make the decision to purchase an HDTV you will most likely direct your attention to the choice between plasma and LCD technologies. Unfortunately, as technologies for both improve, the line distinguishing the two becomes blurred making this choice significantly more complex. To help you navigate through this process it helps to remember that the primary difference between plasma and LCD technologies is how they process and display video signals.

Plasmas use hundreds of thousands of tiny pixels that create electric pulses that cause rare natural gases to emit different frequencies thus producing light. Here, these pixels act as minuscule red, green, and blue light bulbs, and if you look really close you can see the individual cells separated by black ribs.

LCD televisions produce light by supplying voltage to liquid-crystal filled cells placed in between two panes of glass. When the electric current hits these cells, specific colors are generated by blocking particular wavelengths of light to enter until the right color is generated.

Once you understand how both styles work you can sort through the varying picture quality measurements and determine which style excel in what matters to you most. Still, before you make a decision it is good to remember that much of the previously held stigmas over the limitations of each style are no longer relevant due to advances in technology.

When LCD televisions first emerged they were limited by size with the largest LCD television still was smaller than the smallest plasma; however, these days are no more as plasma and LCD televisions are offered in similar sizes. Also, plasmas were known for the "blacker" blacks, but with a warning that this could be accompanied by a potential burn-in problem. Once again, the problem of plasma burn-ins has become less of an issue with technology advances.

All in all, the best advice anyone can give you is go to a local retailer and see which picture you prefer most, because in the end that's all that really matters.
