The projector consists of LCD and DLP projector From the current chip
projector. As the different sizes and different imaging principle, the size
of the projectors used the two different chips are also different.
LCD projector’s core component is the LCD panel. This technology used in
projectors is older and more mature. With 0.5 inch LCD panels being used
and improved optical design, LCD projector products have reached the weight
only 1.6kg, so the portable ability has received a good development.
In contrast, DLP portable projector used DMD chip has an advantage in
portable performance. Generally we consider that the projector is portable
when the weight is less than 2.5kg. But the weight of the portable
projector used DLP processing technology is only 1kg or less. So it usually
is considered the super lightweight projector.
In general, the application of portable projectors for business is not
usually used to demonstrate the complexity video or animation. But in
general it is used to demonstrate the static documents, charts, for
example, Word, PowerPoint documents. So portable projector can meet the
business needs completely.
When the applications of mini projector are used for mobile business and
training dozens of people, generally the projected area is in 60 inches or
less. So, it do not need a portable high brightness product.
What should be considered when choosing and purchasing
When choosing a portable projector, the performance is the important point
to compare the different product. If you want to buy a portable projector,
you need to pay attention to brightness, contrast, resolution, lamp life
The brightness of mini projector is generally between 800 to 2000 lumens.
Users should select the size of the projector’s brightness to purchase mini
one according to their size requirements and the environment brightness. In
general, if the demo environment area is 15 square meters and there is
poorly lit, the projection brightness of 800 lumens is sufficient. If there
are some light in the presentation environment, the 1000 lumens are
appropriate. And if there is in the open space and strong light
environment, you should consider about 2000 lumen projector. It should be
noted that the current general machine used in the whole semi-dark room can
also have good results. Brightness will also be different because of
different projection distance. the projector farther away from the screen,
the image brightness will be lower.
According to the different imaging principle, portable LCD projector may
reach 400:1 contrast ratio, and the DLP portable projector can reach 1000:1
contrast ratio. Obviously DLP projector is better than LCD one in the
indicator of contrast ratio, but this does not mean that we must choose DLP
projector, and in fact the general document projector only need 400:1
contrast ratio. Users can try to use it and know the projection effects
when choocing or purchasing.
In the market some store staff will advise you to buy the best image
resolution machine, while we recommends that users according to their
actual usage to select. For example, if your projector is usually used
together with the notebook, it’s great to select the resolution projector
same as you notebook’s resolution. Current portable projector is available
to reach the general resolution of 800 × 600, which can meet the needs of
the general projection. At the same time, we should note that the prices of
general projector will increase with the resolution enhancement.
