Projectors are electronic devices that project an image from a video source
onto a screen. With the rapid advancement in technology, projectors have
also seen dramatic improvement in their quality and features. Projectors
are nowadays used in a variety of applications at home and office. While
they offer the advantage of transferring movies or television programs onto
a giant screen for that cinema effect, projectors can also be used in
conferences to display presentations for a large group of audience.

available options to go for, then the article seeks to clear your doubts by

further split into three different rays, each of which passes through
different LCD panels. The panels are further fitted with a filter that is
assigned to one of the three basic colors i.e. blue, green or red. The
panels also have umpteen small sized pixels, which permit or obstruct light
to create different images on the screen.
DLP Projector : Similar to an LCD projector, a DLP projector also has a lamp that emits
light. The one major difference, however, is that unlike panels, the light
in a DLP projector is reflected by a chip that consists of numerous small
mirrors. The mirrors vibrate and produce light modulation needed to project
images on to a screen.
