With the introduction of the computer, the projection system came into
being for the benefit for the meeting room, off-site presentation, common
technical computer presentation, classrooms, where at a time you have
number of people viewing the screen at a time.
Computer projectors are very helpful to display images to a large audience.
The computer projector usually consists of a box that contains a bright
lamp and also a fan so that it remains cool, on the top that is a large
Fresnel lens that collimates the light. In that way the whole screen can be
viewed in a large size. The computer projectors are mostly common fixture
for the classroom and the business and office conference room. The computer
projectors have succeeded upon the overhead projectors, and in its place
the computer projectors has came into being. Such devices have allowed the
making of the presentations very ease by using this. The computer projector
system eliminates the requirement of creating the hard copy transparencies
to make the presentation, which can be quite expensive too.
There are varieties of computer projectors available in the market. The
cost and varieties of all those projectors depends upon the amount of light
that shall be displayed, the technology that has been used for the
mechanism that creates the image and determines the resolution. Mostly
projectors are used in a dark room since the amount of light that is
produced by it is very low and it will not work well and the images would
not be clear if the amount of light is more.
So, if you are using the projector in a room where the light source is more
than you may require more power than the one that is used in an enclosed
room where there is no outside light source. The computer projector has a
very high resolution which totally depends on the computer screen
resolution. A remote control is also provided with it that allows you to
zoom in and zoom out and an optical cursor independent of the system. There
is an interface cable that is available for any type of video sources and
personal computer connectivity.
It is advised that you should not look at the projector light directly
since it is very bright and can affect the eyes if direct contact is made
with it. The computer projector lens is very delicate, special care should
be taken while carrying it. A hard case is always supplied with the
projector, which you should always use while transporting in order to avoid
any damage. The latest and the modern projectors are designed in such a way
