subject: Buying Portable And Mobile Projectors [print this page] Mobile projectors, also called portable projectors, are some of the best selling products for both homes and offices to use for everything from home theater systems to conference room meetings. If you are on the prowl for a new portable projector, you have to become familiar with a few key points before you swipe that credit card. There are many different features that are available on many different models, so you want to make sure that you get the right combination of features in order to get the most and best use out of your machine.
One of the first characteristics of mobile projectors that you will notice is (not surprisingly) their size. They are smaller and lighter as well as not as bulky as the permanent projectors that are out on the market. This is obviously for ease of transport. Be sure to note the carrying weight of the different models of portable projectors you are considering. You will also notice that they come in a wide variety of colors, which is just something to throw in either for fun or for elegance, whichever look you are going for. No matter how low the price is that you will pay for your mobile projector, it should always have advanced technology that delivers distinct, crisp and clear contrasts and brilliant colors.
Todays new digital portable projectors, whether they are for business purposes or they are to be used as home theater systems, depend on receiving an electric signal from a data source. The electric signals for the machines can be either digital or analog, and by data source we mean a VCR, DVD player, Blu ray player, etc. The electric signals are transformed into an image which is then projected onto a screen. If the signal that is sent is analog it must be converted to a digital signal first. This is done by it passing through an analog to digital signal converter.
Right now there are two types of technology that are used for portable and mobile projectors. These are the LCD (or liquid crystal display) and the Digital Light Processing (DLP) technology. The DLP projectors use something called a DMDT chip to process the digital signal. The light source is passed through a color wheel and onto that chip. The light then is reflected off of the chip through the lens, then onto the screen. In an LCD digital projector, the digital signal is processed to polysilicon panels. A light source is passed through a series of dichroic mirrors. which separate the various color wavelengths through the polysilicon panels. Then, activated pixels in the mobile projectors process the light into a final compilation, which is then projected through the lens and onto the screen.
