FILM STRIP PROJECTOR
An optical instrument in which a strip of film is wound past a lens at a fixed speed so that the frames can be viewed as a continuously moving sequence on a screen or wall.
FILMSTRIP
A length of film containing still photographs, often of illustrations, diagrams, charts, etc., arranged in sequence for projection separately and used as a teaching aid.

OVERHEAD PROJECTOR
A device like a box with large stage on the top surface. Light from a powerful lamp inside the box is condensed by special type of lens known as Fresnel lens and passes through a transparency placed on a stage.
SLIDE PROJECTOR
A slide projector is a device that is used to view photographic slides by using optical and mechanical methods. It contains an electric light bulb. focusing lenses. reflector and condensing lenses. a holder that holds the slide.

OPAQUE PROJECTOR
A device that operates by directing onto a material a very strong incandescent light, which is reflected upward to strike a mirror which aims the light beam through a series of lenses onto the screen.
DLP PROJECTOR
Digital Light Processing (DLP) is a display device based on optical micro-electro-mechanical technology that uses a digital micro mirror device which is video projection technology, developed by Texas Instruments.
DLP tech can be used in a variety of video display platforms, but is most widely used in video projectors. It is also important to note that in the past, DLP technology was used in some rear-projection TVs (rear-projection TVs are no longer available).
LCD PROJECTOR
A projector which incorporates an LCD panel and a light source. Such a projector is usually portable, and has a much more powerful output than an LCD panel without the light source. An LCD projector may also incorporate other features, such as a cordless mouse for simplified operation.
LED PROJECTOR
A projector like any other projector only with a difference that they use an array of Light Emitting Diodes as the light source, negating the need for lamp replacement.
PICO PROJECTOR
A handheld projector (also known as a pocket projector, mobile projector, pico projector or mini beamer) is technology that applies the use of an image projector in a handheld device. It is a response to the emergence/development of compact portable devices such as mobile phones, personal digital assistants, and digital cameras, which have sufficient storage capacity to handle presentation materials but little space to accommodate an attached display screen.
