front-projection TV
A device that projects TV onto a white or silver fabric screen that is wall, ceiling or tripod mounted. It uses the same types of technologies as data projectors, which accept computer output, but projection TVs are designed to process standard and high-definition TV signals. Many units can do both.
Front-projection TVs are used in home theaters, and high-end units can display an excellent image on 8-foot and 10-foot screens. When built into the room, the screen is typically hung in the ceiling and operated by remote control. The TV is either ceiling hung or mounted high up on the opposite wall. See data projector and rear-projection TV.
Front Projection Screen Size Can Be Changed
Front-projection TVs can change their screen size by replacing the screen and moving the unit closer or farther away. Although they can be fairly large, the screen in a rear-projection TV is a fixed size.

| Front Vs. Rear Projection |
|---|
| Front-projection TVs require a separate screen several feet from the unit, while rear-projection TVs are self contained. However, front projectors can create a much larger image than rear-projection systems, and the screen size is flexible. |
