What is a Projector?
The Basic Definition of a Projector is, “It is a device that uses light to project an image or video on a surface”.
In simple words, it is a box-like device that has a light source, lens, and other parts. By connecting the Projector to a device you can project images, videos, games, etc. on a larger scale on any plain surface, like a wall, screen, or other flat surfaces.
Previously, Projectors were mostly used in movie theatres, schools, and offices. However, in 2024 people are using it for Home Entertainment as well. There are also mini projectors that you can carry with you for outdoor use. We have covered all the different Types of Projectors in another article.
Why Do We Need a Projector?
Now that you know What is a Projector, you should also understand why do we need it. Basically, whatever you see on a Computer or Mobile Screen can be projected onto a larger screen.
The computer screen is small in size, so the information on it will only be visible to fewer people. But, when there are a large group of people, they need a bigger screen. Making or Buying a Large Monitor will be very expensive. And it will also be difficult to install it everywhere. Therefore, Projectors were invented.
The term “projector” may also refer to any device that projects light (such as lasers). However, most projectors use lenses and mirrors instead of lasers because their performance characteristics are better suited for these applications than those of laser-based devices.
The Projector is a very useful invention in the field of Technology. It projects the image from a PC/Mobile on a surface (Wall or Projector Screen) so that the data/information is visible to a large group of people.
Projectors can be used for diverse purposes. They are often used in business, education, and professional fields. They can also be used for home entertainment, gaming, and other purposes.
Keep reading as we will be discussing the uses of Projectors, the benefits of using Projectors, and the History of Projectors.
