Rear projection TVs are similar to regular TVs in that they are the bulkier of the two choices (front and rear projection). They also compare because the image projected is basically bounced off of a mirror like device and then out to the television screen.
Because everything is housed within the Rear projection TV, there is less concern for the lighting in the room. The lighting that affects the image is controlled inside the device and not by ambient room lighting. This also means less wires and space taken in your living room, because everything is already inside the set. The optimal screen size for rear projection viewing is around 70”.
The convenience of the Rear Projection TV comes at a price. The larger, CRT rear projection TVs are often bulky and extremely heavy. Some of the larger screens can weigh about 500 lbs. If purchasing an LCD or DLP rear projector, they are leaner, and can weigh as little as 200 lbs, but are more expensive.
The digital display technologies that involve a rear projection method consist of DLP, LCD and its many variations including LCoS. The fixed-pixel displays project each pixel individually, usually from a reflection into lenses that focus the light into narrow beams onto a screen. The screen that catches the picture from the inside is very much like the screens used for CRT. These present a larger viewing area.
Rear projection TVs are the most affordable available, but remember they are bulkier. This means a big chunk of space on your living room floor will be taken up by the rear screen projector TV. Rear projection TVs are much easier to configure into your Home Theater System and involves fewer wires and less time planning out your room, because everything in the TV is self contained. The biggest drawback to a rear projection TV would be the floor space needed. Another drawback to the rear projection is the brightness of the picture when viewing it at an angle. Despite enhancements in recent technology, the bigger rear projection screens do not provide the best picture when viewing from an angle. Replacing the bulbs can be quite costly. A replacement bulb is in the neighborhood of about $300.
Rear projection TVs are used by the majority of television viewers in the United States. This is mainly due to the cost comparison with the front projection TVs. When considering a Home viewing system, consider all of the aspects, pros and cons to both front and rear projection TVs. TVs are getting cheaper, but they are still a very big investment. Consider how important the alternatives are to you. Do you have little space in which to put a TV? Would you rather not hassle with managing wires and hookups to your TV? These are questions only you can answer, but think them through carefully.
