A projector is a great tool for the office or the classroom, making it easy
to displays lessons or presentations. Traditional projectors used a
combination of light, mirrors and magnified glass (rearview projectors) to
display translucent slide on a uniformly screen. Words and pictures were
enlarged on a wall, making it easier for the presenter to use visuals while
discussing lessons. Despite the move away from these rearview models, there
are a number of new projector models to choose from.
Rearview Projector The original model that was widely in use within classrooms. Utilizing a
series of light, mirrors and magnified glass, the rearview model was
durable, often lasting for years. The downsides to this type are that it
does not display digital images and is heavy, making it not moved easily
moved around. The benefits to this model type are that there are many in
circulation and you can sometimes find them used for a bargain price.
LCD Projector This is one of the most common models in use today as it can be plugged
into a digital source and used to show images on a computer screen. This
type has also been used in home theatre systems and is capable of being
plugged into a DVD player. While providing seamless functionality alongside
other digital products, they LCD projectors are still very expensive and
not everyone can afford to purchase one.
Laser Projectors Still relatively new to the market, laser projectors have not gained too
much popularity yet because the technology is still new. Because the image
is projected with a laser, you don’t have to use it in complete darkness to
see the images being played. Similar to the LCD versions, digital products
can be projected using the laser models. The downside to this technology is
that it is expensive and there is only one model that is available for
consumer purchase, which is both portable and easy to hook up.
