Get a Data Projector!

Data Projectors: For the more imaginitive people out there.

So how do data projectors work? Data projectors take a video signal and project the image using a lens system. They utilize a very bright light and can be configured to fit the user’s preference. However, it must be noted that there are several type of date projectors. Lets take a look at some of these in detail.

An LCD projector sends light from a Metal halide lamp that goes through a prism which separates it into three poly silicone panels to cater to the red, green and blue components of a video signal. When the light strikes through the panels, individual pixels can be opened or closed, either allowing or blocking the light to pass. The combination of opened and closed pixels is able to produce different ranges of colors.

DLP projectors use digital micromirror devices.

LCOS projectors use liquid crystal on silicon

LED projectors use Light Emitting Diodes as light source

So now that we have an idea of the available types of data projectors and how they work, here is a list of some of the worldwide brands that offer this product.

As you can see, data projectors are quite popular as they appear on the product line of numerous brands.

Being that their main purpose is to project imagery coming from a source, lets take a look ath some of the other similar devices that somewhat have the same functions and purpose.

The television screen is a basic example, with it's purpose being to transmit images coming from a signal. The main difference between this and a data projector is that the images are projected on the tv screen while for data projectors, images are projected from the device onto a separate screen. The same can be said for standard computer monitors who take the signal from the CPU and then projects the image on itself. Data projectors do the same except that again, the image comes from it and is projected on a screen

You may be wondering what use a data projector might have. Well, in the modern world, data projectors are often used in clasroom settings in giving lectures and are espcially helpful in presentations, which is not limited to only educational purposes. In addition to that, data projectors can also be used for less serious purposes such as for a home entertainment theater and for live events. If you think more creatively, you can even use them if you want a wider screen when playing your favorite video game! Data projectors have many uses and sometimes you just have to think out of the box to figure some of them out.
