Home Theater LCD Projectors
The most important aspects of a home LCD
projector are its feasibility and efficiency,
combined with its usefulness. Compared to the CRT
projectors, an LCD chip is amazingly small. An LCD
projector is also a viable option in terms of power
consumption, which is quite low.
LCD home theater projectors are ideal for
business presentations, since they operate
successfully in rooms where light is inadequate. An
LCD projector is also the most viable and admirable
choice for home theater use. One of the key features
that make LCD projectors popular is that they are
reasonably priced compared to CRT types.
However, the home theater LCD projector is not
free from limitations. An LCD projector can
frequently display ""the screen door effect"". As
the screen consists of separate pixels, the pixels
can be evident on a big screen, thereby giving the
illusion of seeing the image through a ""screen
door"".
An LCD chip consists of a section of different
pixels, and in the event of one pixel burning out it
presents an irritating black or white blotch on the
projected image. Separate pixels cannot be restored,
and if a single pixel burns out or the number is
greater, the complete chip has to be changed.
One of the crucial factors that should be given
adequate emphasis is the fact that the LCD light
source in an LCD projector must be substituted from
time to time according to the use of the projector.
The ideal time to effect the necessary change should
be after every 1,000 to 2,000 hours of use. However,
the cost can be quite high, going up to a few
hundred dollars. Changing the bulb also has its own
advantages, since a fresh lamp refreshes the
brightness and contrast, and the user can fit bulbs
without much difficulty. |
