When it comes to projectors, they are basically categorized into two types, namely CRT projectors and LCP projectors.

CRT Projectors – These projectors are the original and they make use of three lenses for the generation of colour images. Each of the the three lenses are placed on a different axis to focus red, green, and blue images individually. CRT projectors provide the image, which are not only clear, but also close to the screen. Hence, they are commonly used in cinemas and public places.

LCP Projectors – These kinds of projectors produce image with the help of liquid crystal panels. The incoming light screening process is done by filters and reflectors, which split the white light into different colours henceforth illuminating the crystal panels, which in turn is converged onto the focal point of a single lens. These projectors are portable and easy to set up.

Depending upon the type of display technology used, the video projectors are further classified into three types; Standard LCD projectors, Polysilicon LCD projectors, and DLP projectors.

The standard LCD projector uses just one LCD panel glass that regulates three colours. These projectors are losing their grip in the market because a better version of this projector uses three crystal panels. The polysilicon projectors is the advanced version which makes use of three crystal panels and hence produce a high quality image. The DLP projectors are the most common of the lot and work on the mechanism of a DLP chip.

Even though the technology used in the projectors is different, the thing that is common among all is the use of projector lamps. To buy quality projector replacement lamps at great prices, you only need to make a stop at BulbToGo.

Liquid Crystal Display (LCD) and Digital Light Processing (DLP) are two different kinds of projector technologies. Both LCD projectors and DLP projectors not only work differently, but also produce different results.

LCD Projectors – A projector lamp is the main source of light in LCD projectors. The light from this source is split into three beams, which then pass through three separate LCD glass panels. Each panel is fitted with a filter assigned to a separate color, red, green, and blue. Further, these LCD panels have numerous tiny pixels. These pixels either allow or block the light to produce the image that you see on the screen.

DLP Projectors – DLP projectors have the projector lamp as the light source, just like LCD projectors. However, DLP projectors differ from LCD projectors in the fact that, the light from the projector lamp, instead of passing through LCD panels, is reflected off a DLP chip, which contains several tiny mirrors. These mirrors, by wobbling back and forth, generate the light modulation needed.

Difference

LCD multimedia projectors produce more saturated colors, whereas DLP multimedia projectors produce higher contrast ratios with deeper black levels. The compact size is another advantage of projectors using DLP technology. When it comes to light-efficiency, LCD projectors have an edge over DLP projectors.

Even with all these differences, there is one thing that is common to both these kinds of projectors – the projector lamp. If the lamp dies out after usage, it can be replaced, whatever the type of projector may be. The best place to buy projector replacement lamps of any kind is BulbToGo.com.
