Transmissive Projectors
A transmissive projector's light source is
controlled inside its bottom. Transmissive Projectors projects light
upwards through the crystal clear image to a lens on the peak of the
unit and out on the outcrop display. Transmissive projectors efforts
very well with printed film transparencies or an LCD section
computer present. This type of projectors give dazzling,

frequently necessitating a cart to turn them among rooms.
Reflective Projectors
A reflective projector's light resource is
including in the top of the overhead projectors. The light of
reflective projectors is projected downward onto a deep tray which
rebound the light reverse up via the lens and away onto the
projection display. These projectors are slighter, light weight and
extra portable than transmissive projectors. Although their images
are not often as sharp or dazzle. They just work well with written
film transparencies.
Slide Projectors
Slide projectors produce image by brisk light
off of a reflector, via a crystal clear film slither and an
image-focusing sphere and away on top of the projection display.
These projectors frequently approach with mechanized slide-changing
instruments, which are perfect for presentation slideshows of 35mm
or 2" x 2" graphic slides. Various projector makers manufacture

famous manufacturer of LCD projectors'
DLP Projectors
Third and final type of multimedia projector
is DLP (Digital Light Processing) projectors produce an image by
prognostic light using a transparent fragment onto a minute reflect
array, substantial in high quality and high organization images. DLP
projectors are massive for office or home theater use and they don't
