There’s nothing like watching your favorite sports activity on a big screen Plasma Televisions, high definition TV. High definition means having a lot more pixels than Standard Definition. Much like a 600 DPI printer will give you much greater detail than a 300 DPI printer, a high definition television will be able to display a lot more dots on the screen than a standard TV. The result - much better picture quality.

The two primary kinds of flat screen TVs are Plasma TV and LCD TV. Along with their other benefits, both of these sets showcase exceptional picture quality. Of the two, it’s generally conceded that the LCD technology produces a better overall image quality - especially in terms of color saturation and more naturalistic skin tones. However, the Plasma models have the advantage in a better “black level” displays which makes the image crisper and clear. Both LCD and Plasma Televisions have their adherents. Which one is better for you is a matter of personal preference which only you can determine.

Old style CRT televisions used a cathode ray or electron gun to paint the screen with a picture. The newer Plasma Televisions work on a different principle

The difference in Plasma Televisions is that Plasma Television don’t use scan lines to display a picture. Instead a plasma TV is pixel based. The pixels form a matrix of cells or transistor electrodes filled with an inert gas. The cells are coated with phosphorous and are sensitive to electrical current and emit red, green and blue lights in response to electric current.

When you turn on the TV, the cells are activated. When you turn it off, the cells are de-activated.This is the same way that computer monitors work. The three primary colors can create all the colors needed. The end result is a crystal clear and smooth image being displayed on the screen. But another reason for the stellar picture quality of Plasma TVs is that while CRT televisions can display images in thousands of colors, Plasma Televisions can produce millions of colors.

Most Plasma Televisions also have a built in line doubler. A line doubler takes an interlaced video source and strip out the extra lines to create a single-interlaced frame output. Essentially it “doubles” the resolution of a regular TV signal. The result is a smoother and higher resolution image. Since Plasma Televisions cannot play interlaced signals directly, they use a line-doubler to change the signal into a form that they can read. There are various algorithms to “deinterlace” a signal and the quality of the resulting image depends to a large extent on which algorithm is used.

People with CRT screens, sometimes have a problem with glare, especially when watching TV in a room filled with sunlight. This is mostly due to the curvature of the screen. Most of the flat screen models, now available, have pretty much eliminated this problem.

Another advantage of Plasma Televisions are that because of the flat screen, they aren’t susceptible to the image distortions that CRT televisions are subject to. So no matter where you view the picture from, you get a true view of the picture.
