Projector - the device which unites a light source, optics system, electronics and display (ы) for the purpose of image design from the computer or device video on a wall or the screen for big consideration of the image. There are hundreds the products available in the market, and they are differentiated by their decision, work and features. These devices can be attached to the computer or video to the device the same as you would connect the traditional monitor.
The term "the large-format film" is used to specify the television size, more than 40 inches in diagonal measurement. Until recently it is usually back screens though we see more and more flat screens at competitive prices.
Address of TV of Back Design (RPTV)
Certainly, there is a big consumer appeal to RPTVs these days. And it is easy to understand. The part it occurs because of simplicity of a product. Eventually, what it could be easier, than receiving bigger TV? If you want the increased image without a disorder and vanity, it can be bought from any local retailer of the large-format film and is put during the day or two.
Another RPTVs address - the impression created by retailers of the large-format film that RPTVs are cheaper, than forward systems of design.
Clearly there is a market for both types of house theatrical decisions. From the practical point of view your size of a room has a direct bearing on the definition, what approach is the best for you. If you have no big room of consideration, 40 inches to 60-inch diagonal TV, possibly, will be much. In this case the solution of back design - more practical acceptance that you can contain a box in space.
But if you want cinema experience with the big screen, and your size of a room will allow it, forward design - a way to go. Forward projectors are made to make images on the screen in a range of 70 inches to 120" to diagonals or more. As soon as people understand that can receive a picture to four times the size for the same money as good RPTV, it opens absolutely new world of possibilities of entertainment.
How good TV of Back Design:
As it is noted above, advantages of RPTVs are obvious. There is a large quantity of products in the various sizes and ranges of the prices. In the majority of areas usually there are some local show rooms. And they are simple to buy and establish.
However, RPTVs have some restrictions which don't do system of forward design. Among them the size of the screen, poor corners of the review, excessive reflections, poor management of a format of the image and area loss are limited.
The Screeb size - appreciable difference, but still costing reflection about for an instant. 100" diagonal forward screens - four times the area of a surface of 50-inch RPTV. If you want to place real "theater" in the private theatricals, the approach of a projector and a screen delivers it. RPTVs - simply big TVs.
