ightness. If you’re going to use it in large rooms or big conference halls its brightness should be from 1,000 to 4,000 ANSI lumens.

First digital projectors, Eidophor projectors were introduced

Digital projectors are equipments of modern technology. These are used to convert image data directly from the computer onto a screen via lens system. Digital projectors provide visualization of data that is actually stored in a computer for presentation. These projectors enable the viewers to watch moving images from a DVD, digital versatile disc player. Advertisers or sellers also use these projectors to give 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 in the formation of home theater systems. These projectors use resolution of SVGA standard i.e. 800?600 pixels in expensive devices. Cost of digital projector is determined by its resolution as well as its brightness. If you’re going to use it in large rooms or big conference halls its brightness should 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 several high quality models of digital projectors are available in market so Eidopher projectors are less common.

Following four technologies are used in digital projectors:

High intensity CRT
LCD projectors using LCD light gates
Texas Instruments' DLP technology
Eidophor oil-film projectors (obsolete)

At present 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.
