    Digital projectors are equipments of recent technology. These are used to convert image data straight from the computer onto a screen via lens system. Digital projectors provide visualization of information that is certainly actually kept in a personal computer for presentation. These projectors allow the viewers to view moving images from the DVD, digital versatile disc player. Advertisers or sellers also have these projectors to offer demonstration of products to a large number of customers. It can easily convert written documents onto an interactive whiteboard.

    Digital projectors play an important role inside the formation of home theatre 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 as well as its brightness. If you’re planning to use 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. Eidopher projectors used an oily surface in a rotating disk with light shining through it and employed an electron beam to disrupt oil in a specific manner. Eidophor projectors were not able to produce colors. Nowadays there are various premium quality types of digital projectors can be bought in market so Eidopher projectors are less frequent.

    Following four technologies are utilized 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 could be configured with one RGB color tube which includes three colors green, red and blue having 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 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 from one spot to another. They are significantly popular and available in a variety of sizes and shapes. CRT and LCD digital projectors come underneath the type of transitive projectors.

    Reflective projectors would be the superior digital projectors that provide good quality images. These are generally affordable and provide next level of entertainment. Everyone can enjoy home theater applications through the help of digital projectors.
