There are different types of projection screens, and they all stand for something yards but the projector displays is only a projection screens, without the projector itself, so it is very important that the projector you get, I will talk to you about these different projection screens . Light reflecting properties of the projector screen is the material it is made of, now for the discussion of the various projection screens. When someone talks about a screen with a gain of one means that the screen reflects all the light evenly over the space in comparison with others or regular white boards.First on the list is the diffusion screen: The Diffusion screen reflects light right across the room, making it possible for everyone to see the same image at the same time and same quality of picture or video. The projector screen is on and thus reflects light in the picture with an even illumination from all different angles in space within the cone of the film screen. Because the light is evenly distributed in space gives the background of the picture, a little bit darker, but nobody knows or recognizes it, because everyone looks the same brightness in the image.

Second on the list is reflective displays: reflective shield is mostly used when there is a high ambient light in space and reflect that extra light away, so it does not interfere in the image on the screen and should not be used on the rear projectors, because it reflects light like a mirror.

These reflective displays works best with projectors that are in front or at a higher projector win, maybe round and a gain of 2, which is the finest projector mounted on the ceiling of the house so they can reflect light from the image into a leaner screening angle. Reflective displays, as you already know, a gain of 2 and because of the high angle of the projector screening angle is much smaller when compared with the dispersion screen.
