Advertisers or sellers also use these projectors to give demonstration of products to a large number of customers. It may easily convert written documents onto an interactive whiteboard.

    Digital projectors play an important 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 determined by its resolution along with its brightness. If you’re planning to make use of it in large rooms or big conference halls its brightness should be from one thousand to 4,000 ANSI lumens.

    First digital projectors, Eidophor projectors were introduced in 1950.

Eidophor projectors were struggling to produce colors. Nowadays there are numerous top quality designs of digital projectors can be bought 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)

    Currently 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 much like CRT television set. These projectors might be configured with one RGB color tube which has three colors red, green and blue 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 generally bulky thats why these represent the best projectors for fixed installations.

    LCD digital projectors are portable and lighter enough compared to CRT and can be easily shifted from a single spot to another. These are generally very much popular and available in several styles and sizes. CRT and LCD digital projectors come under the class of transitive projectors.
