Projector types – The choice lie on your output of work.

The LCD (liquid crystal display) projectors have only one panel of LCD glass that controls the 3 primary colors – red, green and blue. Currently these projectors are becoming less common in the market, as DLP projectors gain popularity. LCD is by far the cheapest of the different types of projectors.

LCD is also more “light efficient" than DLP meaning an 850 Lumen projector will produce a brighter image than an 850 Lumen DLP projector. LCD also tends to produce more saturated colors than DLP, hence people perceive it to be brighter overall. With LCD producing a sharper image, it can lead to a bit of disadvantage for video, as it makes the pixilation more obvious. In general, DLP projector technology is preferred for home cinema and portability, but LCD types of projector better where color reproduction is of importance.

DLP (digital light processing) projector types use a single chip with thousands of micro mirrors to modulate the lamp’s light and project it through the lens. These types of projectors are composed of over 400 000 tiny mirrors, which modulate light from a lamp and project the “modulated" signal out through the lens onto a screen. DLP projector types are one of the more common types of projectors on the market.

DLP is the future of the home cinema, but due to the high cost of manufacturing these projector types, LCD and CRT projectors are more reasonable options on the cost front. One of the drawbacks of DLP technology is that in any given instant, the picture on the screen is not the total image, but instead it’s constantly changing between images of the individual red, green and blue colors. So in the end the eye and the brain play the last critical role in making these projector types work, by integrating the picture, so that the viewer perceives the image and not the flashing components of the image.

CRT projector types are the largest and most experienced player of these three. You will usually find them at your local bar or in the school auditorium. CRT uses three tubes. The three colors combine to form the image. These machines don’t have a fixed number of pixels, making them versatile and capable of clear images from higher or lower resolution sources. These projector types might also require calibration by a professional from time to time. They are also generally used in fixed installations because of their size. CRT’s are typically not as bright as the other technologies, but the refined picture quality is difficult to improve on.
