Choosing Between a Plasma and LCD TV - A Technical Comparison
With the developments in high definition technology creating it the new standard in both broadcast media and residential theater setups, the question of which HDTV tech is better, whether an LCD TV or a plasma TV, has become harder to answer, as these rival technologies have advanced to some extent where the variations between them in terms of displaying a picture, become virtually indistinguishable. many that deal in high def TV's, a minimum of those that are not connected to a single manufacturer or technology, would usually say that selecting between a plasma TV and an LCD TV is a matter of personal preference, of course, creating such a alternative would be laborious unless one knew the variations of every within the initial place.
Plasma TV's get their name from the technology they employ to provide a picture. A plasma TV's screen is formed from voluminous cells containing rare noble gas mixtures that when subjected to totally different charges ionize (become electrically charged) and illuminate either red, green or blue phosphors at completely different levels to provide different colors. LCD TV's on the other hand, as their name suggests, are composed of a liquid crystal sheet that is sandwiched in between two glass panels that, when the right quantity of electrical charge is applied filter white light provided by either an LED or fluorescent backlight into either red, green or blue, so manufacturing, at the right combos, the different of the visible spectrum.
In terms of picture quality, Plasma TV's have traditionally performed better than LCD TV's as each cell during a plasma TV is essentially a light bulb, manufacturing a color when charged, and because it's "off" when not, creates a deeper black. LCD TV's manufacture pictures by blocking white light, so in darker environments, blacks in LCD TV's will still appear rather brighter in comparison to plasma TV's. In brightly lit environments, on the other hand, the distinction between the 2 is minor. One should keep the quantity of ambient light within the room where they are alleged to install their TV in mind when selecting between the 2. Plasma TV's also show fast-paced pictures better as they virtually have no response time (the delay it takes for pictures to be displayed on the screen). Newer models of LCD TV's have greatly improved in this aspect, but can still experience motion blur when displaying fast-paced pictures.
As for energy consumption, LCD TV's generally use fifty % less energy than plasma models, as it takes additional electricity to power the individual cells during a plasma TV than it does for an LCD TV's backlight. Even with the recent development of improved energy consumption within the newer models of plasma TV's, they still require a third additional energy than LCD TV's of identical show size.
With the enhancements in both technologies, the longevity of plasma and LCD TV's are sually enthusiastic about the manufacturer. both TV's can claim a minimum of one hundred,000 hours of viewing time before photos begin to fade or dull, within the case of LCD TV's the backlight begins to dim, though in some models these are often replaced, extending the life of an LCD TV indefinitely. Plasma TV's on the other hand will inevitably lose its phosphoric parts on each individual cell, (though admittedly after a very durable of use) and these can not be replaced.
There are other variations between the 2 technologies that may vary depending on the specifications of the manufacturer, so knowing 100% which is better between them will still rely upon who you ask. manufacturers will of course promote their own models because the larger alternative, and arming yourself with additional information will assist you separate the facts from the hype.
