Differences Between LCD And Plasma TVs

By Jason Thomas

There are many televisions on the market today, with several different types of displays. However, the two types of television most often discussed are the LCD (or Liquid Crystal Display) television and the Plasma TV. Each of these two types has its own unique advantages and drawbacks.

Lets start with the LCD television. This television utilizes individual lights to create the image on your screen. These televisions have a relatively long life span, at an average of fifteen years of use. An LCD television is also lighter than the televisions that you have grown accustomed to, and it is even lighter than many of the Plasma Televisions that are available for purchase. An LCD has high levels of brightness, however the contrast and black levels is where the LCD television starts on the downward slope.

As mentioned before, the LCD uses individual lights to create the images, therefore it must block out these lights to create black. Also on the negative side of LCD televisions is the pixels. When the viewer is watching a fast paces show, such as a sporting event or an action film the image will often be unclear and look pixelated.

Plasma televisions, which use individual pixels to create the images, are known for having one of the best brightness and contrast rates and for having some of the truest achievable blacks. They are only available in sizes of 37 inches and above, however, generally speaking the Plasma TV is usually the more affordable choice in the 42 inch and up category. Plasmas have no "sweet spot" - they are viewable from nearly any angle with little or no loss of picture quality. Like the LCD, the Plasma TV is relatively lightweight.

Although plasmas are a truly great television to purchase, there is one major drawback and that is the stamp effect of the images on the screen. The stamp effect refers to the "burning" if images on the screen after it has been on the television for a length of time. Therefore, if you leave your television on a channel that keep the logo on the screen all day you may find that your televison has a "ghost" image of the logo even after you switch to a new channel.
