Digital projectors are equipments of contemporary technology. These are used to convert image data right from your computer onto a screen via lens system. Digital projectors provide visualization of web data that may be actually kept in a personal computer for presentation. These projectors encourage the viewers to observe moving images from a DVD, digital versatile disc player. Advertisers or sellers also employ these projectors to present demonstration of products to numerous customers. It could easily convert written documents onto an interactive whiteboard.

Digital projectors play an important role within the formation of home cinema systems. These projectors use resolution of SVGA standard i.e. 800? 600 pixels in expensive devices. Value of digital projector depends upon its resolution along with its brightness. If you’re planning to apply it in large rooms or big conference halls its brightness must be from one thousand to 4,000 ANSI lumens.

First, digital projectors, Eidophor projectors were introduced in 1950. Eidopher projectors used an oily surface within a rotating disk with light shining through it and employed an electron beam to disrupt oil within a specific manner. Eidophor projectors were struggling to produce colors. Nowadays there are several high quality kinds of digital projectors can be found in market so Eidopher projectors are less common.

Following four technologies are employed in digital projectors:

High intensity CRT

LCD projectors using LCD light gates

Texas Instruments’ DLP technology

Eidophor oil-film projectors (obsolete)

At the moment LCD projectors use Texas Instruments’ DLP technology whereas the high intensity CRT devices are suitable for enduring installations. Entire working of cathode ray tube digital projectors is like CRT television set. These projectors may be configured with one RGB color tube that has three colors red, blue and green with a single lens, one black & white tube having a rotating color wheel or three RGB color tubes with three lenses. Projectors having cathode ray tubes are often bulky thats why they are the best projectors for fixed installations.

LCD digital projectors are lighter and portable enough in comparison to CRT and can easily be shifted in one place to another. These are typically significantly available and popular in a variety of styles and sizes. CRT and LCD digital projectors come underneath the type of transitive projectors.

Reflective projectors are the superior digital projectors that offer top quality images. These are affordable and provide next stage of entertainment. Anyone can enjoy home theatre applications through the help of digital projectors.
