Projectors have become an essential element of offices, schools, and universities. A presentation can not be completed without the use of a projector. Projectors are almost universally used in presentation rooms.

In this article, we’ll discuss about different type of projectors (CRT, LCD, and DLP), how they function, available, applications, advantages and disadvantages.

What is a Projector and How Does It Work?

What is projection? Simply put, it’s the act of projecting information or imagery to a screen. Projection has been done for years. Shadow play is popular among children and, while it is simple, it serves as the basis for projector technology. Let’s look at how it works in detail. An obscure, dim picture of the thing may be seen on the wall or display screen if you put an item or image in front of a light source. A moving image is known as an animated image.

In basic terms, a projector takes the operational idea of picture projection and applies it to video or image input. The projector receives a video/image input, processes it with the help of its built-in optical projection system that comprises of a lens and optical source, and projects the improved output on the Projection screen.

The term “laser projector” is sometimes used to describe a laser projection system. A projector projects a figure or picture on to a surface, which is generally light in color and may be a projection screen, white screen, or even a wall. In large gatherings, projectors might be utilized as an alternative to televisions or monitors.

A projector may be used to show a presentation on a big screen so that everyone in the sitting area (may be a classroom or a conference room) can view it, for example. Projectors create either static pictures like slides or moving pictures such as films.

The projectors can be divided into several categories

Projectors can be classified into three categories based on their display characteristics. They are as follows:

• CRT – Cathode Ray Tube;
• LCD – Liquid Crystal Display;
• DLP – Digital Light Processing.

#1 CRT – Cathode Ray Tube

A projector is a device that projects videos. The small cathode ray tube in a CRT projector has high brightness for image production. A lens is positioned in front of the CRT face to help focus and expand the picture onto a large projection screen. The image or video is focused by the lenses of a CRT projector to display it on screen. The picture is manipulated with the assistance of three separate colored (red, green, and blue) CRT tubes.

Light guns are required for the CRT projectors as they are too large and hefty to be carried about. Because of the three light weapons, their electricity consumption is also high. It may at first appear to be difficult and tough to set up a CRT projector, but users claim that it has a stunning and magnificent picture quality.

These projectors are said to be less expensive than newer technologies and are compatible with future development.

#2 LCD – Liquid Crystal Display

The meaning of Liquid Crystal Display is self-explanatory, given the name. The words LCD and solid are similar in sound and meaning. A Liquid Crystal Display projects certain images or objects via liquid crystal. This is a display screen that has an incredibly thin film coating on it. It’s commonly utilized in computers, laptop displays, televisions, portable video games, and cell phones. LCD displays are thinner than CRT displays because to their technology.

#3 DLP – Digital Light Processing

The Texas Instruments Digital Light Processing (DLP) is a video technology that is utilized in front and rear projection equipment. DLP is used in both front and rear projections. It’s common for TVs to use back projection, but it’s also used in front projectors for businesses and schools. A DLP is available in two distinct forms: a 1-chip DLP and a 3-chip DLP. Digital Light Processing makes use of micro mirrors known as a Digital Micro mirror Device to reflect light and shading onto a screen.

These tiny mirrors are installed inside a semiconductor chip and are tiny. Texas Instruments is the primary manufacturer of DLP chips.

Projectors may be used in a variety of ways, including

#1 Classrooms

Projectors are used in instructional settings to demonstrate a subject. With the help of a projector, films or photos may become more interesting and children may easily learn by having fun. Furthermore, we can instantly zoom-in or -out the image to ensure clear vision and find tiny details.

#2 Companies

For meeting, presentation, and conference functions, large MNCs and businesses rely on projectors.

#3 Home

Projectors may also be used as home theaters, with the ability to view a film or other series on a big screen with outstanding audio quality, giving the impression that you are watching live.

Advantages of Projector

The benefits of projectors include:

• Size of the Large Image. The largest possible picture size is produced by rear projectors. You may utilize them to create a large-screen presentation of a business film theater in your home. Projectors can produce beautiful pictures with a 90″ to 120 “diagonal, which is far larger than anything you can get with flat-screen TVs or rear-projection TVs.
• The Best Alternative to a Huge Screen Television. A projector is a less expensive alternative to a 60″ plasma television. The projected image is usually quite bright, and projectors can be utilized with some of the room lights on.
• Low price for the projector. Ceiling projectors are the most inexpensive option for big display screen video in your home. Some projectors are built with a focus on dedicated residential theater and have fallen under $1,000; this price is considerably less than flat-screen TVs or rear-projection TVs. Given the low cost of many entry-level projectors, this is an excellent way to have a big screen experience at home. Though you’ll need to add another speaker, the enjoyment you get overcomes that.
• Energy Efficient -> Inefficient Saving Space. A tiny projector that is mounted on a rear shelf, bookcase, or the ceiling takes up no room in the space. It’s hardly visible when not in use.
• It’s simple to put in. They’re light, and one person can easily unpack them, connect them up, and capture a photo on the wall without difficulty.

The following are some of the disadvantages of projectors

• A projector is rarely used in a brightly lit environment.
• It needs to be maintained on a regular basis.
• In some instances, the installation price may be greater because it is dependent on how you install it.
• A separate audio system is required for most of the projectors.
