LCD projectors range in price from a few hundred to several thousand dollars, and are available from companies like Epson, Panasonic, and others. It uses liquid crystal chips with a mirrored backing.

Each technology has positives and negatives, and there are good and bad projectors that use each technology.
Lastly, if you're unsure if projection is right for you, check out the aforementioned "Projectors vs. TVs: Giant-screen pros and cons. Contrast ratio is the most important aspect of picture quality. It is the main determinant for how realistic an image looks. Better even than plasma. Sony's SXRD comes in second. LCDs have come a long way in recent years, and some now offer some excellent performance in their own right.
DLP, however, has not. Most projectors have an Auto Iris, which closes to dim the image on dark scenes, and remains open to keep bright scenes bright. While these do improve the apparent contrast ratio somewhat, the higher native contrast ratio of the LCoS projectors still looks better overall. For more on this, check out "Contrast ratio or how every TV manufacturer lies to you.
I tie this in with contrast ratio. Both JVC and Sony models have a high native contrast ratio, offering deep blacks at the same time as bright whites. Projectors with an iris can do one or the other and not at the same time. This is a tough one, as light output varies a lot between projectors. LCoS projectors tend not to be as bright as certain LCD and DLP projectors, but recent LCoS projectors offer more light output than any projector from just a few years ago, so I consider all "adequate" in this regard, with some being more adequate than others.
Color accuracy varies a lot per projector. I've reviewed projectors with accurate color from all technologies. So if your projector is placed 10 feet away from the screen and has a throw ratio of 1.
Ideally, you should be sitting at a distance that is more than twice the width of the image. To make things simpler, many manufacturers offer a distance calculator on their website for various models. Here, you just input a distance or required screen size.

Yearly Save DLP projectors produce a smoother image with no shadows.
DLP projectors can produce the rainbow effect with brief flashes of color across the screen. The LCD projector is more light efficient and has a good color saturation. LCD projectors produce a brighter image with the same projector wattage and have high brightness capabilities.
LCD projectors produce a sharper image which is more precisely focused. LCD projectors score higher when it comes to the brightness, an essential projector feature.
LCD projectors are bulky since they consist of too many internal components and are difficult to carry around. The LCD projector can fail fast, and the parts are expensive to replace. And finally, LCD projectors lose image quality over time. LED is not a display technology. LED projectors have a significantly smaller footprint than those that use traditional projector lamps.
LED projectors are similar to most other projectors. The only difference is the projector bulb. LEDs last at least 10 times longer than traditional projector lamps. Many LED projectors can run for 10, hours or more.
