What is Projector

A projector is an optical device that projects an image (or moving images) onto a surface, commonly a projection screen.

Most projectors create an image by shining a light through a small transparent lens, but some newer types of projectors can project the image directly, by using lasers. A virtual retinal display, or retinal projector, is a projector that projects an image directly on the retina instead of using an external projection screen.

Types Of ProjectorsThere Are Three Type of Projectors they are 1. LCD2. DLP3. CRT

DLP Projection :-

DLP technology is based on an optical semiconductor called a DMD chip (Digital Micro mirror Device), which was invented in 1987 by Texas Instruments (cant remember the guys name). The way it works is that a DMD chip is made up of millions of tiny mirrors, that can rotate at a 10 degrees angle (12 degrees on better models).

On the DMD chips, shade is usually extra using a shade controls. This can be a controls in which rotates rounded something by 150x for each second to 250x and even more. A lot of the more affordable products will be made up of your several message shade controls. This will be Red/Green/Blue and generally a clear message

LCD Projection :-LCD Projection is by far the cheaper method of getting great home cinema. I have a Panasonic PTAE500 myself which is great and highly recommended. LCD (liquid crystal display) projectors contain three separate LCD glass panels, one for red, green, and blue components of the image signal being transferred to the projector. As the light passes through the LCD panels, individual pixels can be opened to allow light to pass or closed to block the light. This activity modulates the light and produces the image that is projected onto the screen.

CRT Projection :- CRT- “Cathode Ray Tube “

This is the largest and most experienced player. Many of you have probably seen this kind of projector at a bar or in an auditorium at a school. CRT utilizes three tubes, sometimes called "guns." The three colors combine or converge to make your image. CRTs do not have a fixed number of pixels, making them versatile machines capable of clear images from higher or lower resolution sources. CRTs also require periodic 'calibration' by a trained professional, which can mean additional expense for the end user down the road. These projectors are generally used in fixed installations because of their size. CRTs are typically not as bright as the other technologies, but the refined picture quality of a properly calibrated CRT is tough to beat. Its worth noting that to replace the Guns, it costs quite a bit of money (on average £500 per gun).

What is Projection ScreensA projection screen is an installation consisting of a surface and a support structure used for displaying a projected image for the view of an audience. Projection screens may be permanently installed, as in a movie theater; painted on the wall; or semi-permanent or mobile,[citation needed] as in a conference room or other non-dedicated viewing space such as an outdoor movie screening (open air cinema).Different markets exist for screens targeted for use with digital projectors, movie projectors screen, overhead projectors and slide projectors, although the basic idea for each of them is very much the same: front projection screens work on diffusely reflecting the light projected on to them, whereas back projection screens work by diffusely transmitting the light through them.
