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 and service.
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.
