What are the real differences between LCoS and DLP projectors? After much
research I have found that very little up-to-date information that is
available. Most websites point out how bulky and costly LCoS projectors and
my research shows otherwise.
LCoS stands for “liquid crystal on silicon” and is a hybrid between DLP
(digital light processing) and LCD (liquid crystal display) technology.
Light is projected through the liquid crystals onto a reflective surface
that projects images. The major advantages to the LCoS are: a reduction in
pixelation because LCoS has more rounded pixels compared to the sharp edges
of the DLP pixels, a reduction in bluring effects, and higher resolutions.
The major disadvantages I could find were: high cost, larger in size, and
shorter lamp life. But, as with any advancing technology, these are all no
longer valid. LCoS projectors can now be found with LED lamps that last
30,000 hours, compared to the 1,000 to 2,000 hours they used to last. They
are not very expensive and can be found as low as $250. And there are pico
projectors with LCoS that are as small as cell phones.
The only remaining objections are that they do seem to run a little warmer
and take extra power. If you are using a battery operated LCoS projector
you may want to invest in a long-lasting battery. The extra warmth means
the fans they use are also a little louder than other types. Overall, if
you can get your hands on an LCoS I would recommend them though they are
much less common than DLP projectors as of now because the LCoS chips are
harder to mass produce.

While working at one of the top mini projector manufacturers in the world,
I became beyond enthusiastic about the possibilities, and decided I would
share this technology with others. It will amaze you how powerful and
convenient handheld projectors can be.
