Plasma TVs Vs. LCD TVs

Plasma and LCD TVs are both higher end TV technologies that produce bright, crystal-clear and super color saturated images. Both generally come in flat screen, thin build casing. Furthermore, in recent years, the price of both LCDs and Plasmas have gown down further reducing the bottom line distinction for consumers.
Picture Quality
Plasma TVs outshine LCDs in situations where there is low lighting, for example night clubs, bars, and home theaters. LCD TVs, on the other hand, have the advantage when it comes to well lit areas, such as airport terminals, public display boards and rooms that are bright and well lit.
Playback
Plasma TVs are better than LCDs in displaying fast moving images often found in sports or video games. They generally have higher contrast levels and faster response times than LCDs. Though LCDs are improving gradually in terms of response time for fast moving images, there’s still a notable delay or lag that occurs in the most fast paced sports and games scenes.
Lifespan
In the past, LCDs had a reputation of lasting longer than Plasma TVs. Plasma TVs produces light through the emission and combinations of gases that, over time, begin to fade. LCD TVs, on the other hand, emit light via a backlight bulb. However, with advances in the development of Plasma TVs, manufacturers are now capable of developing Plasma TVs that remain functional much longer than before. LCD TVs, according to manufacturers, last around 50,000 to 65,000 hours of use at which point their backlight usually dies out. Plasmas have a half life of 60,000 hours, at which point the brightness levels of the display halves, making everything look dimmer. When it comes to lifespan, the make and model of the TV would give you better insight rather than comparing LCDs to Plasma TVs.
Size
When it comes to size, both Plasmas and LCDs are evenly matched. Both come with screen sizes (diagonal length) 60" and higher. Plasma TVs have an advantage over LCDs in that they can be manufactured in larger sizes without a decrease in picture quality. LCDs, however, often face difficulties with pixel defects (burnt or dead) as the units increase in size. However as manufacturing processes improve for LCDs, the gap between Plasmas and LCDs should decrease dramatically.
Computer Use and Gaming
LCDs win when it comes to gaming and computer use because LCD TVs don’t suffer from flicker or screen-burn in. Screen-burn in happens when fast moving images get “burned” onto a screen, leaving a residue or trace of previous images on top of new ones. Also given the high density of pixels per square inch, LCDs are well served in displaying large amounts of data and pictures that retain great detail, such as in video games.
Plasma manufacturers have done a great deal to address screen burn in with new motion adaptive anti burn technologies. However, for the serious gamer, LCDs are still king.
Price and Screen Resolution
LCDs, as previously mentioned, have a high density of pixels per square inch in comparison to plasma screens which gives them crisper and more detailed images. For example a 40" LCD has a resolution of 1366x768, while a 42inch Plasma HD would only sport a resolution of 1024x768. The difference in resolution may be difficult to detect for the average viewer, but avid sports fans may notice the slight difference.
While LCDs have better resolution per square inch of screen size, Plasma TVs have the advantage of larger screens for lower prices. Since large LCDs are expensive to make, their cost is higher. The choice between the two comes down to which you prefer: better resolution or a larger screen.
In the end the choice between purchasing a Plasma or LCD TV comes down to preference of features and price. Comparing specific models is more effective than comparing technologies because they both offer high quality, super color saturated images with comparable screen sizes.
