There are many questions to ask when making a decision on purchasing electronic products. Asking the right questions will lead you to the best option out there for you. What kind of features does it have? What are the specs? And the important question of price. How much should you pay and is it worth the money.
We’ve put together a guide to help clear out some of the fog if you’re considering buying the latest trend in personal projectors. Mini projectors also known as pico projectors and micro projectors is a growing industry and here’s what you should know.
Currently there are 4 different technologies used to make pico-projectors:
- DLP is using tiny mirrors on a chip to direct light from a LED source. Together with LCoS this is the most popular technology today, used by many companies including Optoma, LG and Samsung.
- LCoS is a tiny LCD panel (or sometimes 3 panels) that filter light from a LED source. Together with DLP, this is the most popular technology today.
- Laser-LCoS is the same LCoS filter as above, but the light source is a laser. Lasers are always in focus, and are bright and efficient, however they suffer from Speckle (more on this below)
- Laser-Beam-Steering is a new technology that uses laser and a tiny mirror (or two) that direct the light, one ‘pixel’ at a time. Because of the laser source, the image suffers from the Speckle effect.
Speckle is “random intensity pattern produced by the mutual interference of a set of wavefronts”. It basically means that there are shiny metallic-like dots visible all over the image, (it’s mostly on static images, videos suffer less). You can see the speckle dots with any laser-pointer as well.
Get the best technology for the best picture. The most important aspect that makes a great mini projector is the image it is able to produce. Look for high resolution projectors and look for high lumens. The higher the lumens the brighter the image.
If you’re going to be using your LED pico projector for multiple uses like watching videos, looking at pictures, or giving a presentation on it you should be in hot pursuit of a pocket projector with media tools built into it. Having the ability to search for files and go from video to images with onboard tools will make your experience with a mini projector more pleasant.
Other features to look for are Input/Output capabilities. Data is stored in a variety of ways these days and it’s a plus if you’re pocket projector can read and play different file types from different file storage like a flash drive or SD card. An outlet to attach a speaker for better sound quality is also a nice feature to have.
Other features that you want to consider would be the battery life and the size and weight. Keep in mind that smaller size means less room for features and technology capacity.
Now that you have an idea of what to look for you can start your search for a small projector and there are many to choose from such as AAXA Technologies, Samsung, and Acer which can be found on Amazon.
