Choosing a new Tv for the home is a major decision. The two main types of Tvs on the store today are plasma and Lcd. These competing technologies arrive at similar features via two very distinct processes. The following paragraphs will discover what these technologies are and how they compare to one another.
Technologies Defined
Plasma flat screen technology uses millions of pixels, consist of glass, gas-filled bubbles suspended in the middle of sheets of glass and painted with a phosphor. When an electric current is applied, the gas becomes excited and turns into plasma. This plasma gives off ultraviolet light, which illuminates the red, green or blue phosphor coating to display the desired color.
Lcd displays consist of a liquid-crystal solution sandwiched in the middle of two plates of glass. When thin-film transistors buzz these cells with an electric charge, the crystals turn and line up to filter white light from a lamp behind the Tv screen. The number of turning determines what color seeps through; the crystal cells block the unwanted colors from the spectrum of light until only the strict color continues through to the viewer.
Picture Quality
In normal to low room lighting such as night time viewing, plasma Tvs display good photograph quality. In contrast, Lcd Tvs are ideal for challenging environments such as sunrooms and for collective display areas. In a typical home environment, a plasma Tv will yield higher photograph quality.
Video Playback
Plasma Tvs generally accomplish good with high-contrast levels and fast-moving images. Lcd Tvs have a longer response time; that is, how long it takes for a crystal to twist and allow light to pass through. Lower response times have less blur and thus are more desirable.
Longevity
Since a plasma Tv works by challenging gases and causing phosphors to glow, over time the phosphors will fade. Although it takes years for the phosphors to reach half their first brightness, ultimately the Tv photograph will come to be dim. The gases and phosphors cannot be refreshed or replaced, so the entire Tv will need to be replaced. On the other hand, Lcd Tvs last as long as their back-lights do. Since Lcds naturally filter light, there are no parts to wear out or fade. Toward the end of the lamp's life cycle, however, the light given off may turn slightly so that the white light is no longer a pure white. With today's advances in technology, both plasma and Lcd televisions may last for years, so neither type has a determined advantage.
Screen Burn-In
With plasma displays, static images such as a paused Dvd will ultimately "burn-in," or come to be permanently locked into the glass display element. This phenomenon is also known as "ghosting." The end result is that even when the static image is no longer being displayed, some remnants of the image will be descriptive to the naked eye. Lcd televisions do not experience this qoute due to the nature of the liquid crystals. Newer plasma Tvs have a reduced danger of burn-in, but if this is still a concern, then an Lcd Tv would be a safer bet.
Size
Both plasma and Lcd televisions are available in larger sizes, although the largest Tvs such as 61" favor plasma technology. All of these sizes have proven reliable, although the largest plasma Tvs consume a lot of power.
Cost
Plasma Tvs generally have lower pricing than Lcd Tvs of comparable size.
Overall, both plasma and Lcd Tvs have determined advantages and drawbacks. Anything seeing transmit to purchasing a new Tv should determine which features are most prominent before choosing in the middle of plasma and Lcd technologies.
