There are mainly two kinds of projectors, video projectors and transparency projectors. Under the video projectors, there are four kinds. These are the LCD projector, CRT projector, DLP projector and LCOS projector. As for the transparency projector, it has the movie projector, slide projector, and overhead projector.

An LCD projector is also known as a liquid crystal display. It uses a metal halide lamp in order to send light through the LCD panels so as to display images. It is the modern slide projector and overhead projector of today.
CRT projectors are popularly known as video projectors. It utilizes high-brightness picture tubes or CRT so as to create an image. The created image is then enlarged and focused with the use of a lens. This lens is placed behind the face of the CRT.

A DLP or digital light processing device uses a Digital Micromirror Device (DMD). It is a small memory chip which adjusts the electromagnetic mirrors for every pixel in the image. It is also good to use even in rooms that are lit.

LCOS stands for liquid crystal on silicon. It is known as a micro-projection technology device which is used for televisions. Like DLP, it makes use of reflective technology but has liquid crystals instead.

Under the transparency projector, the movie projector uses films on a reel to form moving pictures. A slide projector also enlarges photographic slides on the screen. The overhead projector also enlarges images of pictorial or written material on a transparency that is placed underneath the projector.

LCD Projector - What Specifications Are You Looking For?

People everywhere are choosing an LCD projector over an ordinary projector because of the amazing advantages they can expect to get. These versatile machines can be used in the home for watching movies and in the office to enhance visual presentations. This type of projector also finds itself being used to teach classrooms full of students at once, making it a great aid to teachers.

The specific advantages of this projector over an ordinary one are numerous. For starters, all images (moving or still) are incomparably sharper when coming from an LCD projector. This feature is one that is most apparent during presentations where the text size of numbers is small, but surprisingly readable. Because of this, presenters can display more information on a single image without worrying about weather or not their audience will be able to read it.

Another advantage of this type of projector is the fact that images are not at all distorted. When video information is fed from a computer to the LCD projector, the projector modifies the image in such a way that it will retain the exact dimensions on the projector screen as it does on the computer screen. It does this all without compromising the quality of the image as well – no harsh pixilation, no color loss.

Color is another great feature of this type of projector. Colors are projected flawlessly to the screen. Unlike old projectors, an LCD one is much more like a television. You can even control the red, green and blue color intensity levels. Also controllable are contrast and brightness, so you'll be able to easily modify your image to fit whatever lighting conditions are present.

If you are considering the purchase of an LCD projector, there are a few things that you should know before setting foot in a store. Perhaps the most important piece of information you need to have is the typical distance you intend to have the projector away from the screen. Every projector fits into a specific distance range and will only perform best when it's used within those parameters.

Also, you should know what kind of lighting conditions are typically going to be present when you're using the LCD projector. This will indicate how bright of a projector you'll require.

Finally, you need to choose between two classes of resolution for your projector. SVGA is a lower resolution, but can offer higher brightness. This type is great for projecting still images in an office setting where it's difficult to lower the brightness of the lights sufficiently to use a normal projector. XGA has the higher resolution and is perfect for little details and the best for moving images. Many people use an LCD projector with XGA resolution for their home theatre needs!

Truly, an LCD projector is a wonderful invention with a multitude of applications. While the cost of these projectors can be a little on the high side, the quality you'll get is well worth every penny.

Summary:

People everywhere are choosing an LCD projector over an ordinary projector because of the amazing advantages they can expect to get. In fact, the resolution and color these projectors boast are so good, many people use an LCD projector home theatre needs!
