Americans love their television sets from the tiny wristwatch set to the large screen unit that has taken over the living room or family room. The large screen television is in essence a large projector hidden behind the big television screen. The rear projection unit needs more space that a flat screen unit.

The television monitor takes in the signals and translates them seemingly by magic into images on the screen. A rear projection television has a projector behind the screen that delivers the picture to the screen. Using lights and mirrors, the technology switches mirrors on and off at thousands of times per second. The projection system is using the digital signal from the monitor to control the mirrors to create the right image on the screen by the projection process. High definition televisions give a clearer picture than any technology before them.

The controls in the new monitors allow you to change the viewing mode of the screen. Full screen is the normal way to watch television shows while wide screen gives movies a home theatre quality.

The screen on a projection television can be LCD or plasma. The abbreviate LCD stands for liquid crystal display. This type of screen may last for up to 20 years but the crystals typically begin to break down after 10 years. The newer plasma screens are the most expensive to buy but give the best image quality on the market today. These flat plasma screens can mount directly on the wall. The plasma screen will give an excellent picture today but the useful life of the plasma screen is between 7 and 14 years.

Signals sent to the television projector are translated into horizontal lines and dots along the line that are called pixels. The following modern technologies allow high definition (HD) and plasma to have excellent resolution: PureDrive, DCDi by Faroudja, DNX by Pixelworks, ACEII, and DLT (Digital Light Processing).

With all the changes in television technology, there is a whole new language to learn when shopping for a big screen television. One of the terms that apply to screens is resolution. A higher resolution equates to a higher quality. The first number in the resolution indicates the number of dots or pixels per inch there are in each line while the second number states how many horizontal lines make up the screen image. The most popular screen resolutions found in the market are 1280 x 768 and 1366 x 768.

Projection televisions can maximize the color aspect of the image or can keep pace with fast action best depending on the make and model. Before you purchase a projection big screen television unit, decide whether you will need clear fast action for sports or better color for general shows and movies.

With all the competition in the high definition and big screen television markets, watch your local electronics outlet for promotional sales on big screen units.
