How It Works

Each pixel in a plasma display consists of three gas-filled sub-pixels (cells) coated with red, green, or blue phosphor Sharp Flat Screens TV's. Electrodes above and below the cells (the top electrode layer is transparent) jolt them with varying amounts of voltage. This excites the gas in the cells to a plasma state, stimulating the phosphors to produce colored light.

Shop where you will get a price guarantee on your Sharp flat screen television

Many retailers will match or beat a lower price from a local competitor, so go to the store with those prices in hand. Even after the sale, some stores promise a refund if they reduce the price of your Sharp flat LCD TV within 30 days or if you find the set selling elsewhere for less. There are usually restrictions, so check the details. Best Buy recently extended its price guarantee on HDTVs to 60 days. Save your receipt and keep checking the ads even after you buy. Wide 16:9 aspect ratios screen and on nearly all current model enough pixels for HDTV resolution. They can be expensive, especially for screens larger than 50 inches. On some sets, the black parts of the picture, such as dark shadows or letterbox bars on wide screen movies, look dark gray instead of black.

Where it is

Plasmas are available from many manufacturers, with 42-inch high-definition models available for as little as $1,200 and 50-inch displays starting at about $1,800. Expect to pay more for top performance, innovative features (such as 1080p resolution), or a really, huge screen.

Decide between an HD monitor and an integrated HDTV. If you are among the majority of consumers who get their HD via cable or satellite, you can save money by buying an HD monitor, which requires an external tuner to receive any TV signals. Integrated Sharp flat screen LCD's cost more, and they generally require a cable box or satellite receiver anyway. Digital-cable-ready sets that use Cable Cards are the most expensive type, and as noted above, this first generation does not offer interactive program guides or video-on-demand via remote control.

Consider the shape.

A screen with the familiar 4:3 aspect ratio is a good choice for regular TV programming. Most DVD movies and a growing number of HDTV programs are formatted for wide screen. A wide-screen Sharp LCD flat screen TV will give you a better HD experience now and be preferable for all viewing in a few years. Content formatted for one screen shape must be modified to fit the other, so you might see bars on two sides or above and below the image. Most 16:9 HD sets can stretch or zoom images to eliminate the bars, but this can distort the picture or cut off the edges.
