Digital projectors are equipments of modern technology. These are widely used to convert image data right from the computer onto a screen via lens system. Digital projectors provide visualization of data that is certainly actually saved in a pc for presentation. These projectors allow the viewers to observe moving images from the DVD, digital versatile disc player. Advertisers or sellers also use these projectors to offer demonstration of products to a huge number of customers. It could easily convert written documents onto an interactive whiteboard.
Digital projectors play a vital role from the formation of home theater systems. These projectors use resolution of SVGA standard i.e. 800? 600 pixels in expensive devices. Price of digital projector is determined by its resolution along with its brightness. If you’re gonna make use of it in large rooms or big conference halls its brightness needs to be from 1,000 to 4,000 ANSI lumens.
First digital projectors, Eidophor projectors were introduced in 1950.

Eidophor projectors were incapable of produce colors. Nowadays there are many premium quality designs of digital projectors can be found in market so Eidopher projectors are less common.
Following four technologies are being used 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 our prime intensity CRT devices are compatible with enduring installations. Entire working of cathode ray tube digital projectors is a lot like CRT television set. These projectors might be configured with one RGB color tube that has three colors blue, green and red using a single lens, one black & white tube by using a rotating color wheel or three RGB color tubes with three lenses. Projectors having cathode ray tubes are often bulky thats why these are the best projectors for fixed installations.
LCD digital projectors are portable and lighter enough when compared with CRT and can be simply shifted from one spot to another. These are very much popular and available in various sizes and shapes. CRT and LCD digital projectors come under the class of transitive projectors.
Reflective projectors would be the superior digital projectors that offer top quality images. These are typically affordable and present next level of entertainment. Anyone can enjoy home entertainment system applications with the help of digital projectors.
