A projector is an output device that can take images generated by a computer or Blu-
ray player and reproduce them by projection onto a screen, wall, or another surface.
In most cases, the surface projected onto is large, flat, and lightly colored. For
example, you could use a projector to show a presentation on a large screen so that
everyone in the room can see it. Projectors can produce either still (slides) or moving
images (videos). A projector is about the size of a toaster and weighs only a few
Projectors are commonly used in classrooms, corporate meetings, houses of worship,
concerts, movie and home theaters. It is helpful to have an understanding of the
different types of projectors. There are two common types of projectors: DLP (digital
light processing), and LCD (liquid crystal display). LCD projectors work by utilizing
polarized mirrors that pass and reflect only certain colors of light. This causes each
channel of red, green and blue to separate and later re-converge via a prism after
passing through an LCD panel that controls the intensity and saturation of each color.
DLP projectors on the other hand areone-chip or three-chip. Each chip houses
millions of mirrors that reflect light thousands of times each second. One-chip DLP
projectors can produce more than 16 million colors while three-chip models can
produce more than 35 trillion colors. This allows DLP projectors to reproduce more
natural and lifelike images. The closeness of each mirror within a chip makes it
difficult to see any spaces separating the pixels and in turn creates a more fluid and
crisp image compared to LCD technology.
