What is an LCD Projector and criteria for judging their viability
An
LCD projector is one of
the latest developments in the field of projectors that allow you to view
images in greater clarity for better viewing. It is basically a video projector
which is used for displaying not only images, but also videos and other computer
data on selected surfaces. It can just be seen as a modern version of the
traditional overhead and slide projectors. These are short and compact and are
also easy to handle- especially using computers or laptops. All you need to do
is set up the control system and you can coordinate what is being projected on
the screen very easily.
To
get maximum picture clarity, it is very important to calculate the throw ratios
and deduce according the size of the screen and the display that is projected.
Apart from that, it also helps to know that an LCD projector is strictly meant for viewing on a flat screen. Thus,
unless and until the screen is totally flat and smooth, the picture cannot be generated
properly.
Also,
select the color of the screen sheet carefully. Usually, most business houses
and schools prefer the color white for the screen surface. This is because;
white is known to be the most neutral color and does not have a tendency to mix
up with the actual color of the images. It reflects light from the LCD Projector perfectly and
there is no scope for confusion. However, if you wish for sharper contrast,
light grey could be a suitable option too. Select the shade of gray carefully
to make sure that the desired outcome is achieved.
If
you are buying an LCD Projector for
the first time, it might help you to know the points that are to be taken care
of and the factors to be taken into consideration. Some of the most important
criteria for judging the viability of an LCD
Projector are:
1. The
brightness and the contrast of the LCD
Projector- find out what the projector has to offer and how sharp the images
are. See what the brightness and contrast adjustment options are and how useful
it is to serve your purpose.
2. The
connectivity and the ports of the LCD
Projector – check how many ports does it have for connectivity
and what kind of computers and laptops it works on.
3. The
weight and the size- this is especially important to note if you have to carry
your projector around a lot.
4. The
life span of the projector lamp- usually an LCD Projector with a lamp life of about 2000 hours is considered
perfect to meet ordinary demands and regular needs.
Other
projectors that are becoming extremely popular these days are the LCOS and DLP
projectors, especially the portable ones like the DLP portable projector that allows corporate persons and professionals to carry
their projectors around with ease.
