Plasma Vs LCD TV - How To Compare Flat Panel HDTVs
Two of the biggest changes in television in the last 10 years are the plasma TV and the LCD TV. These types of televisions offer flat panels and can be placed in more places in the home than older types of TV's, such as mounted on the wall. But the main questions are: what is the difference for plasma vs lcd tv? How does one compare lcd and plasma tvs? and what are the pros and cons of each type of flatpanel television? Plasma vs. LCD: How Do They Work? A plasma TV uses small gas plasma cells that charge electric voltage in order to create light and a clear image picture. Basically, every picture element that comes from a plasma TV is a small light source in and of itself. LCD TV's trap a solution of crystal between two small polarized glass sheets. An electric current passes through the sheets with the liquid crystals and then rotate, which then changes the polarization of the light passing through responding to the voltage that is applied. The result is either more or less light that passes through the polarized glass in order to reach the display screen. One of the main differences between a plasma TV and an LCD TV is LCD panels do not generate light. They either filter or decrease the light by a source of backlighting in order to create the image that is seen on the flat screen. Pros and Cons to Each Type of TV There are pros and cons with plasma TVs and LCD's TVs but both give high definition picture, which cannot be beat. A plasma TV is better for TVs that have a larger picture and better contrast than LCD TVs. There is also better color accuracy and better tracking motion with plasma TV's. However plasma TVs can have more burn-in static images than an LCD TV. The plasma TV will generate more heat than a LCD TV because it needs to use more light. It has also been shown that plasma TVs do not work as well as LCD TV's at higher altitudes. Plasma TV's also do not have as long of a life span than a LCD TV. A plasma TV has a life span of generally about 30,000 hours, while an LCD TV doubles that with about 60,000 hours. Technology is always improving and life spans for plasma TV's are increasing. One of the main advantages of the plasma TV is the size. Both types of TVs give HDTV but plasma TVs are better for larger models, as generally LCD TVs are not generally found in models that have screen sizes that are above 42 inches. Again this is changing as technology improves. Currently LCD TVs are also more expensive than plasma TVs. The debate rages on of plasma vs. LCD but they are both great televisions that give the viewer a crystal clear unparalleled picture. Between these types of flat screen TVs the disadvantages of each type diminish as time passes, as technology improves. The one thing that they do have in common is they both are head and shoulders above other types of television in terms of the quality of the picture. It will not be long when every television broadcast is in HDTV and because of this it is a good choice to have either a plasma TV or an LCD TV for your television viewing pleasure.
