The good news is that the decision on what kind of set to buy will be limited to some extent by how you plan to use it. For example, if you want a large screen that saves space and can be hung on a wall for a stylish look, your options are narrowed down to Plasma screen TV's and LCD screen TV's. From there, you can further narrow the choice based on other factors. For example, if you're going to be using the screen in relatively high ambient light levels or for displaying your computer's desktop, the LCD screen is the display of choice. LCD technology also consumes less energy than a Plasma screen and doesn't create a humming noise characteristic of Plasma screens when functioning at altitudes above six thousand feet. The Plasma TV screen is better for lower light levels and is easier to find in larger sizes than an LCD screen. It still has the disadvantage of being more expensive than an LCD screen at any given size though.
If space isn't as much of an issue, you might want to go with a projection TV. In the case of an LCD based projection screen TV, the image is created using an LCD screen in the back of the unit and is then projected onto the screen with back lighting. It actually functions just like a flat screen only the viewing surface and the image producing LCD film are separated by feet rather than millimeters. A DLP display actually uses tiny mirrors to split white light into its component colors and then project that light onto a screen. The mirrors are positioned on a special chip and there's one mirror for each pixel on the screen. The major advantage of a DLP display is that it produces an incredibly detailed image with a vast array of colors.
DLP projectors work in the same way as DLP projection screens, but the image is projected onto a screen across a room. That means that a DLP projector can allow a screen to be so large as to be measured in feet instead of inches. By using a pull down screen and hiding the projector, it's also relatively easy to give a home theater set up using a DLP projector a low profile when it comes to a room's decor.
Hopefully this article will help you to sort out which kind of television technology you'll want to use when you go to choose a television set of your own.
