LCD Projectors - The Jist
by: Eli Aloisi
An LCD projector is a device utilized for displaying video images or data. They are the modern equivalent to the slide projector and overhead projector used in the past.
LCD (liquid crystal display) projectors usually contain three separate LCD glass panels, one each for the red, green, and blue components of the video signal. As light passes through the LCD panels, individual pixels can be opened to allow light to pass, or closed to block the light, as if each little pixel were fitted with a Venetian blind. This activity modulates the light and produces the image that is projected onto the screen.
With a lens that "projects" the image on any flat surface and does not require large "furniture" (like a big TV would), LCD projectors tend to be smaller and much more portable than older systems. The best image quality can be accomplished with a blank white or grey surface to project on, and for this reason dedicated projection screens are often used.
Early systems were often intended to be used with existing overhead projectors, built as a large "plate" that was put on the projector in place of the transparencies. This provided the market with a stop-gap solution in the era when the computer was not yet the universal display medium.
This technology is employed in some sizes of rear projection television consoles, as there are cost advantages when employed in mid size sets (40 to 50 inch diagonal). This is not expected to have much longevity in the "home theater" marketplace due to expected improvements cost/performance of competing technologies, particularly in direct-view LCD panels at the lower range of sizes and DLP projection in the larger sizes.
In 2004 and 2005, LCD front projection has been enjoying a come-back because of the addition of the dynamic iris which has improved contrast up to the levels of DLP.

Mitsubishi?s Bright New Idea
Mitsubishi?s Bright New Idea
by: John Richardson
Mitsubishi Electric Corporation is well known for their HDTV rear projection sets. Chances are that you have seen those models that utterly dominate large living rooms, and look similar to big square-like boxes that, if hollowed out, could accommodate a family of rottweilers. Those large monsters, in which the picture quality never looked very good from an angle, will soon be relegated to museums, because rear projectors are getting thinner at a fast clip. Now, Mitsubishi is pioneering a new way to approach the rear projection HDTV-they are using Lasers! With this new idea from Mitsubishi, a RPTV (Rear Projection Television) is transformed because a Laser replaces the usual mercury lamp in the rear of the set. The model is still considered a DLP (Digital Light Projection) but the light comes from red, green and blue Lasers! LASER, which stands for light amplification by stimulated emission of radiation...

HDTV is What Technology is All About
HDTV is What Technology is All About
by: Scott Bianchi
If you have not yet watched TV on an HDTV you do not know what you are missing.
When they promote high definition they aren?t kidding.
When my daughter was born I knew I?d be spending a lot of time at home so I invested in an HDTV and two years later I still think it was an excellent purchase.
Not only is the picture unbelievable but the sound is much improved as well.
More and more channels are starting to come out in HDVT format so buying an HDTV
makes much more sense now as compared to two years ago when I bought mine.
When I first got it I think there were only four channels I could watch in HD.
They happened to be four channels I watched a lot so it worked out well for me.
As time has passed the TV?s themselves become even cheaper and more channels are available so they are a much better purchase.
Many people are not...

Projector Buying Tips: The Best Projector Shopping Guide
by: Robert Thatcher
Technology has always been known to make people?s lives better. In fact, some surveys said that 8 out of 10 people who were interviewed showed significant representation of people who were relieved to have the best technology in their lives.
One of the primary reasons why technology is deemed as life?s enhancers is because it can unleash the limits set upon the rigidity of previous inventions.
This goes to show that with the new trend of technology, people can expect a better life because it provides a hundred and one ways of making the impossible doable.
Take for example the case of projectors. Before, projectors are known to be used in movie theaters and during business presentations or seminars.
But with the continuous technological advancement and development, projectors are now known to be used even at home. This is especially true to those who...
