This document summarizes different types of projectors and their key features. It discusses overhead projectors, opaque projectors, and digital light processing (DLP) projectors. DLP projectors use thousands of microscopic mirrors to move pixels for higher contrast and clarity, and provide greater brightness than liquid crystal display (LCD) projectors. The document also lists some inputs, throw distance, and price range for DLP projectors. It discusses advantages like a large picture size, cost savings, and space efficiency, as well as limitations such as needing a dark room and separate audio system.

2. • A projector is a device that uses
light and lenses to take an
image and project a magnified
image onto a larger screen or
wall.

4.  A single panel is for a single colour,
meaning one panel handles all the pixels
that are created by the red colour,
 The second for blue and the third for green.
 The colour images travel as three separate
beams of light and hit the wall. Here the
colours fall on each other to produce the
true colour.

5. DLP
• (digital light processing) uses thousands of
microscopically small mirrors, which not only
move pixels closer together for higher contrast
and greater clarity, but also provide greater
brightness than LCD projectors. DLP’s high
resolution makes it ideal for projecting images
or videos in HD (high definition). Like LCD
projectors, many DLP projectors also feature
audio.

11. ADVANTAGES OF USING PROJECTOR
• Largest possible picture
• Smaller images a great
option also
• Low cost
• Space saving
• Easy to install

12. LIMITATIONS IN USING PROJECTOR
• Dark room often required
• Maintenance required
• Installation can be more involved
• Separate audio system required
