Portable Digital Projector Basics and Buying Suggestions

Right now you will find three projector technologies available on the market. The two most common technologies associated with a portable digital projector are LCD (liquid crystal display) and DLP (digital light processing). An additional technology, LCoS (liquid crystal on silicon) is much more of a newcomer in comparison to the DLP or LCD versions and is quickly becoming popular with the more serious enthusiasts.



DLP projectors generally have stronger contrast and better black levels, while the LCD alternatives possess better color saturation, generally less fan noise, and run at a lower temperature.



There are several differences between a portable digital projector which is LCD and one which is DLP. These differences should be looked at when deciding which projector would best suit your requirements. DLP projectors deliver images by using a color wheel that may sometimes produce a "rainbow effect". This particular effect may cause some people to see a momentary flash of color. DLP projectors that utilize faster color wheels have reduced this effect, but have not totally eliminated it. Location with regards to the display screen can also be more of a challenge when using a DLP projector as compared to a LCD. At the same time, LCD projectors have an issue termed as a "screen door effect" where images appear as if being watched through a screen. General opinion is usually that the DLP projector has the edge mainly because it produces a more cinematic image, while the LCD version is a little better priced and less costly.



One added advantage which a DLP portable digital projector has over an LCD projector is being able to preserve color accuracy with time. An LCD projector can, after prolonged use, fall victim to "color decay". This the yellowish green that can show up in the display and the only way to fix it is to either replace the LCD panel or replace the projector . The picture from DLP projectors is reflected digitally to the display screen, which totally eliminates this potential problem.



One other technology, LCoS (liquid crystal on silicon) is more of a newcomer compared to the DLP or LCD models and is quickly becoming popular. LCoS projectors generate a high-quality image and don't suffer from the rainbow or screen door effect. Initially, LCoS theater projectors cost between $10,000 and $15,000. Even though recent technical advances have helped lower the cost for these types of projectors, they're still a bit higher priced than either DLP or LCD versions. It isn't difficult to find LCoS portable digital projectors priced under $2,000.



Even though you usually can feel confident purchasing from most of the established brand names these days, being aware of certain specifics can be quite helpful when buying any portable digital projector. Obviously, the ultimate decision is going to be dictated by your needs and your price range.
