Portable Projector

When shopping for a portable projector there is quite a bit you will need to know about them beforehand. First off, there are different technologies that are used for specific types of portable projectors. Two of them in particular are readily available for purchase and are extremely common with portable projectors.

Usually a portable projector will use one of the following technologies: liquid crystal display (LCD) or digital light processing (DLP). There are differences between the two and the overall quality and performance of each will differ. As well, the price is going to vary by model and the technology used in the design will be a major factor in the price range of the machine.

LCD vs. DLP
Each technology has its own strong points. LCD projectors are not very loud while in use, do not heat up while in use, and usually are designed with an improved color saturation. On the other hand, DLP projectors may be loud while in use, and heat up as well. However, DLP projectors still prosper in certain areas. For instance, they generally have a higher quality of contrast and black levels.

There are also certain differences between the two types of portable projectors as well. When looking for a particular model to purchase you should factor in these differences to your decision.

DLP Projectors
These projectors operate with a color wheel that is used to project the images. The result of using a projector with the color wheel technology can be a rainbow effect on the image projection. The issue with this is that it can cause a short color flash during projection. The rainbow effect will not be as noticeable on DLP projectors that have fast working color wheels though. However, even with the best DLP projectors, the rainbow effect will still exist.

Setting up a DLP projector efficiently can also be a bit more stressful than it would be with a LCD projector. The main reason for this is that placing the projector in correlation with the screen is somewhat difficult. Even with this issue though, LCD projectors have even worse issues with coordinated projection.

LCD Projectors
LCD projectors have a significant issue that makes projection quality not what you may want it to be. This is an effect that is often referred to as the “screen door effect” which is a major issue as it tampers with the visual display of the projection on the screen. Basically, when using a LCD projector it will look as if you are viewing the projection while looking through a screen. Obviously this is an issue if you want extremely high quality projection.

The DLP projector does produce a much more cinematic image which is higher quality and definitely preferred. However, the difference in quality may not be enough to foot the extra amount that you would have to pay. LCD projectors are fairly cheaper than DLP projectors. Therefore, it is a matter of determining how heavy each positive and negative characteristic weighs in and decide if you should invest extra, assuming you have the budget for it, to get a DLP projector.

LCoS Projector
This is the third type of projector that is available. Liquid crystal on silicon is the technology behind this particular type of projector. It is relatively newly developed but is gaining a lot of popularity as of recent. The main reason for these projectors getting so much attention is that the image is very high quality in comparison to your other alternatives. You do not have to worry about the rainbow or screen door effects that are associated with DLP and LCD projectors.

While these projectors can be a good investment based on the quality and performance, the price tag does affect many people’s decision when considering if they should buy this type of projector. A LCoS theater project can cost as much as $15,000, but you can find a portable LCoS projector for less than $2,000 if you looked hard enough.

Overall, if you have the wallet for one of these types of portable projectors then you may want to go that route. DLP projectors are fairly inexpensive and reliable enough for most situations, as are LCD projectors. On the other hand, if you want extremely high quality then you may want to go with a portable LCoS projector instead.

You should also look at various factors that play a role in how convenient the device is for you. When buying a portable projector in particular you will want to consider the weight, dimensions, preparation time, flexibility, and much more. Consider all the important factors and find the best portable projector within your budget based on what you are looking for. Also, take a look at reviews to find out about other’s experiences with specific models or brands of portable projectors.
