Be it for personal entertainment or for making business presentations; Projectors are the ideal choice! When you need to play your videos on screens bigger than the biggest TV in the market, projectors/ beamers are the only options you have.

If you think about it, projectors are the exact opposite of cameras. While cameras convert the light to digital signals or a chemical change on a photographic plate, they do the reverse of that. Instead of receiving the light, they spit it out to project an image on a plain surface. This serves a purpose similar to that of a TV or a computer monitor. But in some cases, they are better than TVs as they are easy to move around and also, you can adjust the size of the projected image by changing the position of the device. But before you start shopping for beamers, read this article to get a better understanding of them. This will help you make better choices when you shop for them.

Types of projectors for your office or home

They are extremely handy peripherals for computers . It is almost impossible to carry around everywhere you want to make presentations. And such a TV, if it exists, is going to cost you an arm and a leg. Even though they are more expensive than a regular-sized TV, when you consider all the benefits of the machine, the price is worth it. However, in order to figure out which beamers you should get four yourself, you should know more about them. Here is a list of the four most types out there. In this article, you will also find some really useful tips that you can use while shopping for them.

LED

The advancements of LEDs have brought about a revolution in projector technology. Nowadays, it is possible to make a machine that does not get hot or consume mind-boggling amounts of electricity. Less heat also means several other advantages. Reduction in heat output means the form factor of the device can be made smaller and more portable. Also, LED bulbs have a longer lifespan than any other bulbs with the same amount of brightness. That’s not all. LED beamers have a wider colour gamut, which means they can produce many more millions of colours than regular devices.

LCD

For most people, LCD beamers are the way to go if they want to project decent images for an affordable price. That is also the reason why they are really popular even today. The blacks produced by LCD projectors are not as good as LCoS, but they are not as bad as DLP either. So, it falls between these two extremes when it comes to image accuracy and contrast. One notable advantage is that they can produce very bright images. This feature makes LCDs suitable for offices and classrooms where it is not practical to completely block the light.

LASER

They are probably the best option out for indoor use there if you can afford them. They make use of laser lights of three colours: green, blue, and red. Individual pixels can combine or block these lights to produce the colour for the pixel. Usually, all other beamers use white light to produce the images. But as we only make use of a fifth of this white light, all the rest of it goes to waste. That means Laser projectors can produce brighter and better images while consuming only a fraction of the electricity.

LCoS

Both LCD and LED styles, produce images by shining the light through certain filters to produce the image. However, in the case of liquid crystal on silicon projectors, the light is reflected using LCoS panels. There will be three LCoS panels corresponding to each pixel to produce three primary colours. And to produce black pixels, the panel corresponding to that pixel will align in such a way as to not reflect any light. This makes it possible for such beamers to produce deep blacks and a higher contrast ratio. That being said, LCoS beamers have other downsides. The maximum brightness of these beamers is low compared to others, making them unsuitable for bright environments.

DLP

These beamers make use of tiny mirrors to deflect light that forms individual pixels. To produce different colours, they have a colour wheel that aligns in certain directions corresponding to the colour. The benefit of this is that DLP beamers can fit in a pocket-size form factor. However, the picture quality of such beamers is not the best out there. These beamers cannot produce deep black pixels and, therefore, sometimes cause ghosting in certain images. Due to colour fringing, you might notice a slight rainbow effect around individual pixels if you look close enough.
