0 1,264

If there’s a product that’s being paid great attention to, after the home theatre projection screens, it’s the Portable LED Projectors. Those who are planning their home theatre setup would be curious to know the kind of projectors that are available out there before they pick one for themselves. 

But before that, if you’ve been living in the woods and unaware of what Portable LED Projectors are, let us ask you a simple question. Have you seen that device that’s always placed in front of the projector screens (not too close though)? The device is the source of light directed to the projection screen. It’s present across all the seminar halls, conference rooms, auditoriums, offices, and classrooms where you watch presentations or a movie or an online class. That system is an LED projector. 

Putting it across in the formal language, it’s a digital projection display system that connects the computers or any other device and projects the video output onto the projection screen. The display that is projected through the LED projectors is an enlarged image version. They could be fixed onto a ceiling, or placed on a table or a stand.

Let’s shed some light on what kind of digital projectors are available out there.

Digital Light Processing (DLP)

We can call DLP one-chip or three-chip. One-chip DLP projectors are capable of producing 16 million colors while three-chip models can churn out more than 35 trillion colors. The millions of mirrors residing in each chip help reflect light thousands of times each second. DLP’s ability to produce and reflect light on such huge parameters is what makes it provide a more lively, natural, and impeccable image experience to the audience. The setup of this type of projector has one physical color wheel to generate sequential colors. 

It is most suitable for environments with natural ambient lighting such as classrooms. 

Some of the most common places it is used for are:

– At Conference halls for delivering presentations

– At homes for enjoying movies, TV shows, playing games

– At telecommunication and utility companies 

– At classrooms for lectures

One of the best DLP projectors in the market is the Wowoto S 3D DLP brought to you by ETC Things: 


 Light Emitting Diode (LED)

LEDs are known to be high-quality projectors that are easily connectable with devices like mobiles, laptops, computers, smart TVs. The LEDs also make for a much better lifespan of over 20,000 hours as compared to the traditional projector bulbs. With LEDs, the projector’s lamp is replaced by red, blue and green LEDs which means there’s no necessity for colour wheels anymore. The absence of colour wheels also eliminates the rainbow effect and the noise created by the wheel. 

Since they are equipped with LED light projections, the quality of images and videos is guaranteed. You could mount them to ceilings or also use them in the portable format.

 That’s it from us for today. We hope this discussion helped you introduce yourself to each projector type and get an idea of what you might want to go for.
