LCD TV Versus Plasma

LCD TV Versus Plasma
Both Plasma and LCD HDTV are great televisions. These are two of the latest developments in television technology. These types of television do not use a cathode ray tube (CRT) that is commonly found in the old television sets. Although both types of television are thin and flat, they have differences in terms of the technology that is used for each type so let's compare LCD TV versus plasma.

The Plasma TV is made of xenon, neon and helium gases contained in thousands of small cells between two glass panels. The gas is electrically charged when the TV is turned on. When this charged gas hits the red, green, and blue phosphors, it produces colored images. These groups of red, green, and blue phosphors are called pixels.

Though it does not use the traditional CRT, Plasma TV still has some of the disadvantages of the old television set due to its phosphor-based electronic display. In the prolonged display of static graphical components, the phosphor compounds, which releases light, will lose their luminescence and will result in screen burn-in. This is where the image is permanently burned onto the screen.

On the other hand, LCD HDTV uses a different technology. LCD panels are made of two layers of polarized transparent material that are attached together. One layer is coated with a special polymer that is used to hold liquid crystals. The current passes through the crystals, which can block or pass light to make images. Unlike the Plasma HDTV, there are no phosphors that light up in LCD HDTV. This is the reason why the LCD is a lot cooler, does not require much power, and no radiation is emitted from the screen.

Plasma TV has larger screen sizes available. More often than not, it has sizes ranging from 32 inches to 65 inches. Meanwhile, LCD HDTV has the available screen sizes ranging from 14 inches to 52 inches. Plasma TV weighs much more than the LCD HDTV.

In the aspect of color accuracy and saturation, Plasma TV has more vibrant and accurate displays than LCD HDTV. The latter has a slow and more complex technology than the former. But when producing static images, LCD HDTV is more efficient in creating colors.
