Projector Screen Material

There are different types of projector screens and they all stand for
something ells but the projector screens are just a projector screens
without the projector it self therefore it is very important which
projector you get, I am going to talk to you about these different
projector screens. The light reflecting properties of the projector screens
is the material it is made of, now for the discussion on the different
projector screens. When someone talks about a screen having a gain of one
it means that the screen reflects all the light equally over the room in
comparison with other or regular white boards.

First on the list is the Diffusion screen: The Diffusion screen reflects
light right all across the room making it possible for everybody to see the
same image at the same time and at the same quality of the picture or
video. The projector screen is illuminated and therefore reflects the light
of the image with an equal brightness from all the different angles in the
room inside the cone of the projection screen. Because the light is equally
spread in the room it makes the light of the image a little bit darker but
no one knows or recognizes it because everybody sees the same brightness of
the image.

Second on the list is the Reflective screens: reflective screens are mostly
used when there is a high ambient of light in the room and needs to reflect
that extra light away so that it do not interfere with the image on the
screen and should not be used on the rear end projectors because it
reflects light like a mirror.

These reflective screens work the best with projectors that are in front or
on a higher projector gain, maybe round and about a gain of 2, which is the
finest for the projectors mounted on the ceiling of the house so that they
can reflect the light of the image in a slimmer screening angle. Reflective
screens as you already know has a gain of 2 and because of the high angle
of the projector the screening angle is much smaller if compared to the
diffusion screen.

Third on the list is the Retro-reflective screens: This retro-reflective
screen is almost the same as the reflective screen also favorable in high
ambient light, but the retro-reflective screens reflect the light directly
back to the source of the light and have a high gain The retro-reflective
screens are not very suitable for ceiling mounted projectors because the
light would be reflected in a upright angle to the source making the image
weak for the persons sitting in the front of the room near the
retro-reflective screen and it these retro-reflective screens work the best
with portable projectors which can be table mounted.

Fourth and final on the list is the Rear projection screens: The rear
projection screens are suitable for all the different conditions and these
rear projection screens are used with back projection projectors. Because
of the projector mounted at the back of the room the ambient light does not
have an effect on the image quality at all.

With the rear projection screens have a gain of 6 which is very high and
produces some of the top quality images even if it is in the lightest
bright light. As you already thought this rear projection screens comes
with a price and are not recommended for someone who are only going to
present presentations it would be a total waste, it is for professional use
only.

If you are looking for a projector to deliver great results for more or
less 20-50 people you should look at the diffusion and reflective projector
screens which will be right for you.
