Most offices and institutions use projectors for presentations, training, movie playing, gaming, and demo of products and services. There are different types of projectors that serve different purposes. For instance, the boardroom and the home are two distinct areas that require different projectors.
But that’s not all that is there to talk about the projectors.
In this post, we will discuss what a projector is, how it works, various types of projectors, and where to buy projectors online.
What is a Projector and How does it Work?
Projectors are a great alternative to a television or monitor in large gatherings.
A projector is an optical device that projects a figure or picture onto a surface. This surface is usually light in colour and it can be a projection screen, a white screen or a wall.
It filters light through a small, transparent lens, and projects this onto a screen.
Common Applications and Advantages of a Projector
The applications of Projectors include educational institutions, big and small enterprises, at home as a key component of a home theatre set-up.
The advantages of Projectors include the ease to create a large display screen experience of a movie theatre in your own home.
It is a superb and cheaper alternative to a large-screen television display. Besides, projectors take up no floor space in the room and entail a hassle-free installation process.
Are there Any Drawbacks of a Projector?
While projectors offer a wide array of advantages, there are a few drawbacks too.
- A dark room is a major requirement for using a projector.
- It requires regular maintenance.
- Installation costs can be more depending on how you get it installed.
- Most of the projectors require a separate audio system.
Types of a Projector
- Cathode Ray Tube (CRT)
It is a video-projecting device and it is one of the most popular types of projectors now. It is equipped with a small cathode ray tube. A lens is kept in front of the CRT to control the size of the projection.
CRT projectors leverage more power to run and have a large size. Its setup is difficult as the initial stage and lacks portability. CRT projectors have three light guns and for this, the picture quality is truly superior. Its images are processed with the help of red, green and blue colours.
- Liquid Crystal Display (LCD)
An affordable option, liquid crystal display projectors use liquid crystal for projecting images on the screen. They are easy to use and portable, besides they are much thinner as compared to the CRT projectors.
- Digital Light Processing (DLP)
DLP is used in both back and front projections. Two types of DLP projectors are widely used. 1 chip DLP and 3 chip DLP.
Digital Light Processing makes use of micro-mirrors to reflect light and shading onto a screen. These micromirrors are situated in a semiconductor chip. DLP chips are manufactured by Texas Instruments.
