    Digital projectors are equipments of contemporary technology. These are used to convert image data straight from your computer onto a screen via lens system. Digital projectors provide visualization of information that is actually stored in a computer for presentation. These projectors allow the viewers to look at moving images from the DVD, digital versatile disc player. Advertisers or sellers also have these projectors to give demonstration of products to a lot of customers. It might easily convert written documents onto an interactive whiteboard.

    Digital projectors play a vital role in 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 is dependent upon its resolution as well as its brightness. 000 to 4,000 ANSI lumens, if you’re gonna apply it in large rooms or big conference halls its brightness needs to be from 1.

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

    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 the high intensity CRT devices are compatible with enduring installations. Entire working of cathode ray tube digital projectors is much like CRT television set. These projectors might be configured with one RGB color tube which has three colors blue, red and green using 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 these are the basic best projectors for fixed installations.

    LCD digital projectors are portable and lighter enough compared to CRT and can be easily shifted from a single destination to another. These are greatly popular and available in different shapes and sizes. CRT and LCD digital projectors come within the type of transitive projectors.

    Reflective projectors will be the superior digital projectors offering top quality images. These are affordable and present next phase of entertainment. Everybody can enjoy home theatre applications with the aid of digital projectors.
